Toronto 1840-2023 and NYC 1869-2023 long-term data bases (regular updates and links to data files)

[Roger Smith]

The meteorological season of summer is in the books, for Toronto it ranked tied tenth warmest with 2011, and it reminds me that I have not generated tables for seasonal ranks at NYC but it was probably closer to 30th there as all three months ranked lower than Toronto. 

Have already mentioned June in a previous post, so July 2021 was a rather average temperature month at both locations, then August went back to being very warm, in fact it was third warmest on record at Toronto, closer to 15th at New York City. Both locations set some new high minimum readings mostly in the last third of the month. 

While August 2021 was very dry at Toronto, both July and August were very wet in New York City which received several tropical remnants and after one rather weak daily rainfall record on May 29th, added five more by September 1st. I usually don't put any early new season data in the files, but as NYC had a daily rainfall record on Sept 1 (7.13") I have the first few days of the month in the updated file. 

So you'll find the links to the updated excel files in this post, if you would like to get the new information this past season, plus some new features that I have worked on in the NYC file, for average temperatures on a weekly time scale, together with extremes identified. There are also expansions of previous record temperature summaries.

September 2021 summary:

Toronto mean 18.4 C (t-22 warmest of 182 yrs with 1985)

adjusted to u.h.i. 17.3 C (t-27 warmest of 182 yrs with 1846, 1920, 1985)

_ _ note was t-21 warmest (raw) and t-26 warmest in the overlapping period, 1865 was the one year warmer in either case before NYC began obs.

rainfall 138.6 mm (16th wettest of 182)

one new daily rainfall record (22nd _ 49.9 mm) _ narrowly edged out the rainfall from Hugo's tropical storm rainfall from 1989 (47.3 mm).

no daily temperature records

---------------------

NYC mean 21.28 C (70.3 F) was t-26 warmest of 153 yrs with 1898, 1945, 1948, and 2007).

NYC adjusted to u.h.i. 20.18 C (68.3 F) (t-41 yrs warmest of 153 yrs with 2007).

rainfall 10.03" (6th wettest of 153)

7.13" rainfall 1st new daily record

no daily temperature records

---------------------

Overall, a quite warm and very wet month although after the 7.13" fell on the 1st at NYC the rest of the month had about the normal September rainfall amount 2nd-30th.

I have edited in the various monthly and seasonal values for Nov 2021 and autumn 2021. The season was quite warm for Toronto ranking close to 8th in both raw and adjusted data, the month of November was closer to normal than either September or October at both locations. In fact Nov 2021 was a little below the long-term average when adjusted for urban heat island at NYC although still somewhat above for Toronto. After rather wet months Sept and Oct, Nov was relatively dry. There was about 10 cm of snow towards the end of the month in Toronto and traces of snow in NYC which is not far from average in both cases. 

Since there will be considerable data to be added for the year 2021, I will hold off on updating the excel files for downloads until that can be added in, so the next time new downloads will be available will be early January 2022. Check back then for a brief summary of 2021 trends and (the link to) those updated files (which will be available in the Net-weather equivalent thread).

The 2021 data have all been entered into the supporting excel files and new versions are now available at Net-weather. Scroll back to the first post in this thread for the link and look for the most recent post in the linked thread. 

2021 was tied third warmest on record for Toronto in this data set, and remained near that level even when earlier years were given the advantage of an urban heat island upward adjustment. NYC was closer to 8th warmest (the official data have not been confirmed, going by the monthly averages the year is around 8th) and once again, earlier years do not push in despite a boost; the recent warmth is somewhat more than just the urban heat island so it is tending to keep the raw data and adjusted data similar near the top. Less prolific warm months such as July 2021 sink down a bit in the adjusted data. 

While NYC had quite a wet year (10th wettest of 153) Toronto was much closer to average. The same trends were in evidence except that Toronto had a very dry August (NYC had excessive rainfalls from late August into early Sept after quite a wet July, and October was also rather wet). The fact that Nov-Dec 2021 turned dry at NYC prevented the year from overtaking 9th and 8th place years which would have happened with just normal amounts of precip in the last two months. 

Although it was generally quite a warm year, records were not unusually frequent, and there was one notable cold event at the end of May with some record low maxima set (unusual in this era) as well as very late traces of snow at Toronto (snow fell in small measurable amounts outside the city around May 29th). 

The data files in this thread have been largely brought up to date now with 2021 ranks inserted. The Net-weather thread has some additional record high min data for years 1869-1900 at NYC, which I won't edit in here because the next step will be to post a more user-friendly log of these as they change through time, but if anyone is interested in reading the material it can be found in the Net-weather version of this thread for NYC years 1869 to 1900. 

(once again, if you're a first time visitor to this thread, go to the original post and you'll see why there is a link to Net-weather, the excel files are too large to upload here)

With the  recent issue regarding the NYC sensor placement (going on 20 years now)  with warm season foliage, wouldn't using KLGA or KEWR be more representative of the NYC climate?

[Roger Smith]

In some ways yes, but they don't have as long a period of observations. If I can get some acceptance from NWS relevant authorities for the integrity of my data base, then they could use it with adjustments they think are justified. I don't feel qualified to make such adjustments without at least discussing the topic with better qualified individuals (including Don Sutherland) who are perhaps more familiar with the details of the site changes and the potential adjustments that might be warranted. I'm a bit more familiar with the problems posed by site changes around the Toronto location in my study, having gone to university and stayed in a dorm on campus where the instruments are now located (they were in a government office building property when I was a student and for decades after that). I don't consider the three sites that I know to be used at different stages of the Toronto observatory to be significantly different in exposure but they have been gradually surrounded by a large city and its urban heat island. There was however a brief period around 2020 when it appeared to me that the Toronto rainfall data was being augmented by daily sprinkler contamination (much more frequent daily amounts than regional stations, albeit rather small ones when not actually weather-related). There I am already making inquiries with Environment Canada about a variety of issues raised. 

As to how much the CP (NYC) data might need adjusting, that would have to be worked out carefully and I don't have any preliminary ideas about what might be necessary or appropriate, if in fact anything is needed. One factor would be to assess whether a gradual "parkland densification" at the site is actually an anomaly for the metropolitan area or if it perhaps represents an evolution of the setting that is not necessarily unusual. I know from some field experience that tree canopies can reduce maximum temperatures in calm weather patterns (warm season) but they can also increase overnight lows by similar amounts so that mean temperatures don't suffer as much with two sources of compensating errors.

Jan-Feb 2022 and winter 2021-22 data have been added to the thread and to the files. Tables in this thread are mostly updated where possible to include 2021 and early 2022 data. 

The winter was a relatively mild one although January was colder than the long-term average, especially for Toronto where it had quite a respectable adjusted mean (u.h.i. compensated) of -7.9 C which placed it near 30th coldest all time. Toronto has also had considerable snowfall this winter, while NYC has had a more average kind of season with most of the snow coming in late January. 

There were record high max and min readings at NYC on Feb 17th (68, 49 F). 

The updated excel files supporting this work can now be downloaded over at Netweather and the link to their location is here:

Here's the comprehensive list for Toronto severity of winters, applied to the interval of winter 1840-41 to present. Rather than going with standard deviation scores, I took the slightly less complicated approach of adding ranks, lowest totals are most "futile" winters and highest totals are most severe ... it's a fairly similar list to Don Sutherland's NYC list based on standard deviations, and I think if I applied that method, this list would only change slightly. The snowfalls are for the entire winter seasons, and the temperature ranks are only for D-J-F. I think this is the same approach Don S took to his winter indices. 

Some of the same winters show up. 1931-32 was probably ranking quite close to the top of futility to end of January, but then the winter turned snowy for Feb-Apr in Toronto and dropped out of contention for that reason. 

I could compare adjusted temps for urban heat island which would tend to move the more ancient cases up a bit, but I decided not to do that because after all this is comparing actual conditions experienced by residents of the city. The weather station is in a very similar location to Central Park in that it's on the university campus just north of the central business district in a "midtown" setting. 

The numbers for 2023-24 include known t-1 temp, and assume 10 cm additional snowfall after Mar 10); the ranks will be adjusted moving forward. 184 winters are now ranked. Ties are broken by least snowfall.  

Possibly a more accurate index would require considering Nov and Mar mean temperatures, however, that would not save 2011-12 which had a very warm March.

Record Low Maxima, Minima by Years _ NYC

The intention was to add logs of record low temperatures to the annual summaries for NYC, but editing those already long posts seems to be straining the pagination to the extent that I can't be very confident that the posts will edit without freezing up or corrupting the information already in the posts. So with the addition of a disclaimer in the 1869 annual summary, here's what will happen to fill in the details ... for 1869 to 1900 (the starter era for records), the daily max and high min are already posted, so I need to post only the low max and min data for those years. Starting in 1901, only the high max are logged, high min and the low max, min will all be required. The first post here will detail the minimum values for 1869 to 1900, showing the records established in the starter era and then what happened to them, if anything (a lot of them survive to the end of data because the urban heat island was weakest in these decades, and it was a cold climatic era). 

The cold records often occur together (low max, low min) either on the same day or adjacent days so the tables will be arranged to show these groupings. In all of the following, ER will mean eventual record. If the record set is later tied, that will show as ER (t 1940) etc. All counts of records include 0.5 counts for ties (or 0.333, 0.25, 0.2, 0.167 etc depending on number of ties, there is one low minimum that was tied six times). For starter era records set, that includes ties within the starter era only. For eventual records retained, that includes ties in later years so that if for example a record was set in 1871 and tied in 1893, those two years would be credited with 0.5 originally set records each, and if the record held up but was tied twice more, then they would each be credited 0.25 for eventual records as well as the other two years (which would count 0.33 and 0.25 when they joined the tied grouping for originally set records). The count in the starter era should be interpreted as the count as of end of 1900, obviously the first set of tied records stood alone until tied. However, since this was a starter set, it would not have been too obvious at first what the range of eventual records might look like. By 1900 this was fairly clear. In fact, the average starter low max is only 1.95 F deg higher than the eventual record, so quite a few of them have survived. 

Any temperatures shown in the tables for low max or low min in brackets are not daily records but are shown to illustrate the range of temperatures associated with the reading that is a record low. The more extreme of days before or after the actual record are used, where applicable, and the date selected is shown when the non-record is not on the same date as the record value shown. (e.g., record low 31 F on Nov 7, 1869, before a low max of 39F on Nov 8th which was not a record; the max on 7th was 43F not shown). This approach may be skipped if the value that would be selected appears anyway for a subsequent or previous date, then a less impressive actual daily associated reading may appear (e.g. Oct 26, 1869, max 47F before record low max next day). 

Dates that set records for both low max and low min are shown indented and the low max information appears in the first of the two rows of data, the low min in the second row. 

Note that the expected number of starter year records of each type at random is 11.4 (365/32 or 366/32). The expected number of surviving records is 2.4 (366/153.2). Since this was generally a colder climate era, the average number of surviving records is more than twice the numbers expected for low max and low min. 

1869 _ The year set 17.17 starter record low maxima, and 8.5 starter record low minima. Of those, 6.83 and 4.0 have survived to the end of data.

1870 _ 4.5 low max, 1.5 surviving records; 1.33 low min, no surviving records. The next year with no surviving low minimum records is 1901. The two records set (one tied twice in starter era and again in 1904) survived only to July 3, 1914 and Feb 22, 1918. The five low maxima fared  somewhat better and two have survived, Feb 21 untied, July 3 tied once, the count from those is 1.50.

1873 _ This was another cold winter (1872-73) with several records set continuing on from the cold Dec of 1872. The entire year was prone to cool spells, and November was particularly cold. There was a total count of 20.0 record low maxima of which 12.5 have survived, and a count of 12.17 record low minima of which 6.33 have survived.

The data base also tracks "coldest since record low" for minima. The first example occurs in 1873 on March 6th (9F was coldest since record of 1872). This particular "coldest since" was tied in 1948.

1875 _ This very cold year was particularly cold in mid-April and late November, but set numerous records throughout. 

For low maxima, the count in the starter era was 23.83, second only to 1888 with 26.83,  and 13.33 have survived. That is the highest total, just ahead of 1888 which has 12.83 surviving low maximum records. The count for 29 low minima was 25.67 of which 14.5 remain as records now. The surviving records are the largest total of all years (1888 second at 12.75) but 1888 had 37.67 starter records to make 1875 second place in that category. 1875 still has a surviving low record of some kind in every month except May and July. Nov 30th 1875 holds the lowest max and min for November.

1876 _ The year had few record cold spells until October, then started to make up its deficit with very cold October and December setting the majority of the records. The two low max records before October were both fairly weak and pushed aside in the 1920s. There were 8.5 record low maxima of which 5.5 have survived, and a count of 12.25 record low minima of which 6 have survived. 

The second instances in the record log of a "coldest since" a low minimum record were on Apr 30 (34F coldest after the 1874 record of 32F) and Dec 2  when 11F from 1875 was followed in 1876 by a reading of 15F that was later tied in 1886 (for "coldest since"). That made the count for 1876 1.5 for this statistic -- the "coldest since" stat is helpful later on in the urban heat island and warmer climate era, to get a better idea of the cold potential of various more recent years. These very early "coldest since" markers are rare due to the frequency of cold years following (until the 1920s at least).

1877 _ This was another weak producer of low records especially for its time, with only 5.5 low maximum records, of which 2.5 survived to the present time, and five low minimum records, count 3.5, of which the surviving count is only 0.33 after a record on July 14th was tied twice later. 

There were also two "coldest since" records which followed record low minima 52F in 1871 (Sep 8, 54F in 1877 was tied five times later in the series as coldest since 1871, and the record of 33F in 1874 (May 3, 37F in 1877 was tied by 1911).

1878 _ This was a relatively warm year for the period, and another rather weak production of record lows, with 4.0 record low maxima, of which 3.5 survive, and 6.5 record low minima, of which 3.0 survive. There was a cold spell in mid-May to mid-June, and the year became somewhat colder than average again in November.

There were no "coldest since" a previous record low minimum readings in 1878.

1879 _ This was a colder year more similar to the period 1871 to 1875, and had a steady showing of record lows; 14 record low maxima had a starter era count of 12.17, of which 9.0 have survived; and from a count of 14.0 record low minima, 8.75 have survived. The coldest intervals were in April, June and November. 

There were also two "coldest since" record low minima, from 1873 (22F on Nov 20 1879 is coldest since record of 21F) and 1875 (30F on Nov 3 1879 is coldest since record of 28F), and neither of them has been tied since 1879.

1880 _ This was a fairly warm year until mid-autumn, then November and December turned very cold and set numerous records. From an original count of 15.5 low maxima, the surviving count was 6.0, and from 18.0 low minima, there are still 6.7 that have been retained. One (June 2nd) has been tied four times since being set (hence the 0.7 portion as another has been tied once). All of these retained records are in November as December 1917 took out several records set in December 1880 at the end of the month. The second half of November 1880 is one of the most significant cold spells of the NYC (and also Toronto) climate record, relative to normal. 

There were two "coldest since" record low minima; 36F on Oct 25 was one of five such readings following the 1879 record of 29F, and 6F on Dec 10 was coldest after the record of 3F set in 1876.

1881 _ The year was quite variable with some portions quite warm but others quite cold, and more records of all types were set than in most years. There were 16.0 low maxima of which 7.5 have survived to end of the data, and there were 15.5 record low minima with 4.5 that have survived. 

There was one "coldest since" record, 21F on Apr 5 was coldest after the record low of 20F in 1874.

1882 _ This was a fairly average year for the climate era, and set 12.83 low maxima with 5.5 of those surviving, and 12.33 low minimum records, of which just three have survived. Jan 24th with a low maximum of 6F is the coldest such reading in January although December has had lower values. (Also it is probable that Jan 22, 1857 was colder). Mid-May and early December were the coldest parts of the year relative to normal. 

There was also one "coldest since" reading in 1882, on Nov 6th when a low of 30F (later tied in 1953) was coldest since the record of 27F set in 1879. It was also 31F on that date in 2012 which probably indicates a structurally colder air mass given the strength of the urban heat island at the various times of previous records.

1883 _ This was one of the coldest years by average temperature but it didn't quite match the production of similar years 1875 and 1888, with . March, September and November were particularly cold. From the original count of 14.17 low maxima, 9.0 have been retained, while from the original count of 13.67 record low minima, 4.5 have survived. 

1883 holds six "coldest since" record low minima, two relative to 1874 records (34F on Apr 29 followed a 32F record low from 1874, and 9F on Dec 15 was one higher than the 1874 reading), two for 1876 record lows, Oct 16th (34F with 1883 at 35F) and Dec 16, 9F later tied by 1917, failed to break 7F from 1876, one for the 1881 Oct 5 record of 34F (37F later tied in 1892 and 1965) -- and one for an 1882 record when on Jan 24th, 2F (tied in 1925) remains coldest since the record of -6F. This count of 4.83 "coldest since" records would  not be broken until 1914. Later on in the series a count of 4 to 6 became fairly common for this statistic.

1884 _ While not quite as cold as the years on either side, this was on the larger scale quite a cold year. From a count of 16.0 low maxima, 7.75 survived as records to end of the data. And from 9.083 record low minima, 3.5 have survived. There is also one "coldest since" a record low minimum, set in 1869, when the 1884 minimum on March 1st (5F) was coldest after the 1869 record of 4F. This came after 1884 set the leap year day records for both low max (12F) and low min (4F). The max of 18F on Mar 1st also missed being a daily record in the starter era by 2 deg (1886 had 16F). Mid-July of 1884 was particularly cool, three consecutive days (14th-16th) failed to break 73F (and 17th also just 75F).

1885 _ This was another of the coldest years. From a count of 18.5 low maxima, 6.33 have survived as records to end of the data (all in March and April). And from 18.67 record low minima, 6.5 have survived. There were no minima that were "coldest since" a record low minimum.  After quite a cold winter, March 1885 was exceptionally cold (17th to 22nd coldest) and this only faded out gradually for the rest of the spring. Some cold periods returned in the late summer and early autumn.

1886 _ The colder trend continued with 17.83 low maxima leaving a remaining 7.25 surviving records, and 16.33 low minimum records with 6.17 of them surviving to the end of the data. The year has one "coldest since" a record low, that being Dec 3, tied with 1876 15F after the 1875 record of 11F. It also had the second coldest minimum for March 2nd (10F) but that came before the record was set in 1891. The portions of the year that were coldest were in the winter and autumn months. Unlike some of the coldest years, 1886 sometimes balanced out cold spells with relatively warm periods, even though it produced cold records at a similar pace.

1887 _ In a cold decade, this was one of the warmer years, and the count of low maxima in the starter era was only 7.83, with 3.83 surviving low maximum records now. Although the year managed 16.67 low minima, only 4.5 of those have survived. Another five minima were "coldest since" record lows from 1875 (three), 1876 and 1885, with ties the count for this statistic was 4.0. The coldest since values were on Apr 18th, 30F was coldest after record 25F from 1875; Apr 19th, 29F (tied in 1897) was coldest after record 22F from 1875); Aug 27, 51F was coldest after record 50F from 1885; Oct 15th, 34F (tied in 1937) was coldest after record 32F from 1876, and on Dec 1st, 11F was coldest after record 8F from 1875.

1888 _ This year had the most low maximum and low minimum records in the starter era but finished second to 1875 in terms of records that have survived, in both cases. There were 26.83 record low maxima, of which 12.83 have survived, and 37.67 record low minima, of which 12.75 have survived. There were also two minima that were "coldest since" a record low, one was 10F on March 5th (record 5F 1872), and the other was March 25th when 16F was the lowest minimum after the 1878 record of 13F. 

March and September-October were particularly cold. Only two of the 1888 records happened after Oct 22nd and if we take the year from Oct 22nd 1887 to Oct 22nd 1888 the counts are even more impressive, For low maximum it increases to a count of 27.83 with 13.83 survivors, and for low minimum, 41.67 with 14.25 surviving.

1890 _ The winter of 1889-90 was very mild and colder weather appeared rather gradually, peaking in July relative to normal values. Mid-July was exceptionally cool. But the year only generated 3.5 record low maxima and none of them have survived. From 7.67 record low minima, 6.0 have survived. This suggests that 1890 was taking advantage of the weak urban heat island to score durable records by radiational cooling in fairly marginal air masses by modern standards. There were no "coldest since" low minimum records set. 

The extinction date for 1890 low maxima was Aug 24, 1937. This is earlier than any of the other years that had record low maxima and failed to retain any. Before 1890 became the first extinct year in this regard, 1936 became the first year not to record any record low maxima, followed by 1939. The next extinction for a year with records was in 1940 (for 1908). Thus by 1940, four years had no record low maxima (1890, 1908, 1936 and 1939).

1891 _ This was a relatively warm year when compared to the two decades previous, but had a reasonably large yield of record lows. From 7.33 low maximum records during the year, the surviving count was 3.83. From 4.58 record low minima, 4.0 have survived. This survival rate of 87.3% was the highest of the starter era, and would not be overtaken until 1910 which achieved a full survival (albeit just one record was set). One would need to go as far as 1945 to find a year that had both a better survival rate and more surviving records. The year had no cases of "coldest since" record low minima.

1892 _ This was a below-average year for cold records. From a total count of 3.5 low maxima, just 1.33 have survived (March 14th and a third share of May 21) and from 2.5 record low minima, 1.0 has survived (July 17). There were four other lows that were "coldest since" previous record lows. These had some ties and the count was 2.83. July 21st (59F) tied 1965 as coldest since record 55F of 1890. 52F on Sept 2nd was coldest after record of 51F in 1886. 38F on Oct 5 was tied with 1883 and 1965 as coldest since the record low 35F in 1881. And the following day, 37F was also coldest since Oct 6, 1881 (36F). May 1892 had the one notable cold spell of the year.

1894 _ The year was more productive for low maxima than low minima. From 13.33 low maximum records set in the starter era, 7.7 have been retained, and surprisingly this is the highest number for any year after 1888. Within the starter era, 1894 ranks 13th of 32 for starter records set and also falls behind 1903 so is 14th overall, but ranks 7th for those that have survived (and therefore is seventh overall since no years surpassed it afterwards). For low minima, 1894 had 10.17 in the starter era and of those only 2.5 survived. The coldest part of the year relative to normal appears to be July but the various records are sprinkled through the entire year, and in addition, there are three "coldest since" record low minima, with a count of 2.5, these being Feb 24th (2F the lowest minimum after the -1F record set in 1873), June 7th (48F was coldest after record of 47F in 1879) and July 10th (56F coldest after 1890 record of 55F which prevented this from being the fourth consecutive daily record set (only one of the other three survives today, see table below).

1895 _ This year resembled 1881 in having rather frequent sharp oscillations from very warm to very cold weather, but its production of record low values was weaker. The high points were similar, namely May, September and December. February of 1895 was notably cold, and there were some chilly days in mid-summer despite some all-time records for heat set at either end of the summer. Out of 6.5 low maxima set, 2.5 have survived. From the 6.5 low minima, four have survived. There were no "coldest since" record lows in 1895.

1896 _ This was a year of frequent contrasts. The winter was generally quite cold and established several record lows. April and May were very warm. The summer remained quite warm, and the autumn was then more variable but had several occasions where lowest temperatures were 1 to 3 degrees outside record range. The overall count was fairly low for the starter era with 5.83 low maxima (3.0 surviving) and 6.5 low minima (3.0 also still remain). There were also three minima which were "coldest since" records, March 13th had 14F (1888 record low 6F), March 14th had 15F (1888 record low 12F), March 24th had 15F (1888 record low 12F) and Oct 25 had 30F (part of a five-way for coldest after the 29F in 1879) for a count of 3.2 "coldest since" records.

1897 _ This was a rather average year and the count of record lows was not high for the starter era or even the longer term. From 5.83 record low maxima, only 2.5 remain, while from 5.5 record low minima, 2.5 remain. There was one "coldest since" record, when 29F on April 19th tied 1887 as coldest since the very low 22F reading in 1875. (The coldest since these being 30F in 1904 and 1926). So the count for this statistic is just 0.5.

1898 _ This was one of the warmer starter years and had a very sparse count of record lows especially for this era. Out of 4.5 record low maxima, the surviving count is 1.5, and from just 1.5 record low minima, 0.5 (a tie for Nov 27th with 1932) remains. There were also no "coldest since" record low minima.

1899 _ 1899 was generally a rather warm year but had two notable cold spells, one in mid-February, and the other in early October. This is when many of the year's record lows were set. From 8.67 low maxima, a robust 6.0 remain including all of Feb 10 to 13. From 6.0 record low minima, only 1.5 have survived. In addition, the low of 40F on Oct 2nd was coldest since the 1886 record of 39F. (count 1.0).

1900 _ This was often quite a warm year, with brief cold spells that set a few records. From the original count of 7.5 record low maxima, 3.5 have survived. From the original count of 5.5 low minima, only one (Feb 27) has survived. In addition, March 12th was the coldest minimum (11F) after the 1888 record of 8F (count 1.0). Three cold overnight lows in May (9th-11th) came immediately before some record highs were set May 13th-15th (84, 88, 90F).

Summary of Records Set in Starter Era (1869-1900)

Over the 32 years of the starter era, 177.5 low maximum records survived to the end of the data. This was reduced from 178.5 as recently as March 28th of 2022 (1893 lost a record to 2022). So that means that almost half the days of the calendar year have a low maximum at least tied if not outright owned by a starter year. The count for low minima is 149.2, which means that about 40% of all days have a record low minimum from the starter era. 

For those 149.2 eventual minima, those with later ties could not produce a "coldest since" value, as those are only valid after the last tie. So from about 140 candidates, 30.233 "coldest since" values were set, not the pace reached in later decades, but given that later decades would have more candidates, probably a fairly similar actual pace, and also it should be noted, as this was a cold epoch without much urban heat island, any really cold night would be quite likely to set a record rather than go "coldest since." The decades with the most "coldest since" values are the 1930s (to 1940) and the 1960s to 1970, and 1970s to 1980. 

The next sets of tables will document how the remaining years changed various starter era records.

Log of Record Lows 1901-1910

For this and later decades, a log will be posted for each year, with a brief commentary, showing the new record low maxima and minima established (or tied with starter era or previous years). The count for the year will be tracked in the last two columns, the first of those two columns will track the low maxima (set in year, eventual end of record) and the second will track low minima (set in year, eventual end of record). 

Values in brackets were not records at the time and are shown to give context. To make the tables more readable with extra columns added, these context values are always on the same dates as the records, in some cases there may have been more extreme (but still not record) values on adjacent dates (and in other cases, these more extreme values are records so are also in the tables). Where record low max and min are set on the same day, if space permits, the two records are given their appropriate former and future reference points, unless it becomes too crowded due to ties, then a second line is used. This simultaneous readout will be apparent in two ways -- no brackets for either value, and two sets of count values. Ties beyond the starter era do not count forward (for example, if 1903 ties 1888, that is given as a count of 0.5 for 1903, but if 1947 also ties, then in 1947 the count becomes 0.33 but remains 0.5 for 1903 in terms of records established. If it is a surviving record then that would alter the count for 1903 (and 1888).

The annual commentaries will show the gradually decreasing expected number of established records which was always 11.4 in the starter era for both types of records. It will now start to decrease gradually ending up at 2.4 by 2022. That latter figure is always the expected number at random for surviving records of either type.

A decade summary will give the updated totals to the end of that decade, comparing trends to those established in the starter era (see last comments in previous post). 

1901 _ The first year of the decade continued the trend of the late 1890s in being a rather warm year with not that many record lows. In fact the counts were just 5.33 and 2.0 for low maxima and low minima. Of those, 3.0 low maxima survived (two are ties, so four dates) and neither of the record low minima survived. There were also no "coldest since" record lows. (expected records set in the year down to 11.1). The extinction date for record low minima was June 17th, 1914. This was the earliest extinction for any year as this was the first year since 1870 not to retain any, and the 1870 extinction date was Feb 22, 1918. However 1908 set no record lows so was out before 1901. The minimum now closest to the eventual record low is the June 17 record (53F) which remains 2 Fdeg higher than the eventual mark.

1902 _ This was a somewhat colder year than some previous warm years but did not produce a lot of records either. The count of low maxima was 6.0, of which 2.0 have survived. The count of record low minima was 5.5, of which one (which tied 1884) has survived for a count of 0.5. There was also one "coldest since" a record value, that being the 8F recorded on Dec 9th (1876 had recorded 7F).

1903 _ The year turned colder after a rather non-descript winter, and June in particular was very cool, especially for daytime highs, being quite a cloudy month apparently the overnight lows were less frequently in record range. Even so, most of the numerous 1903 records (beating the starter era) were eventually replaced. Therefore from a count of 16.5 (not equalled since 1903), the eventual count is just 5.25. That is nevertheless higher than all subsequent years except 1917, 1918, and 1963. The low minimum count during the year was 7.0, of which 2.5 have survived.  There was just one "coldest since" a record minimum, 36F on Oct 25th part of a five-way tie after the 1879 record of 29F, leaving a count of just 0.2. While June was exceptionally cool, the rest of the summer continued to set occasional record lows.

1904 _ 1904 was one of the coldest years of the 20th century but had a relatively modest production of record lows, the more salient feature was the nearly total absence of above normal temperatures. From an original count of 7.5 low maxima, 4.0 have survived, and from the original count of 4.083 low minima, 2.0 have survived. The expectation at random has now dropped to 10 records per year (366/36). In addition, there were three instances of a minimum being "coldest since" a previous record low. These were Feb 16th (2F coldest after record 1F 1888), Apr 17th (30F was coldest after record of 27F 1875), and Apr 20th (27F was coldest after record of 24F 1897);  in addition to those, 3F on Jan 18th was coldest between 1875 (1F) and 1982 (0 F), and 2F on Jan 19th was coldest between 1875 (-1F) and 1994 (-2F). The count for the "coldest since" stat is 3.0 but was 5.0 in 1981.

1905 _ This was a rather bland year for temperatures with a warm summer and few extremes. The counts are sparse, from 1.5 record low maxima, 0.5 have survived (a tie for June 7th, 61F) and from 1.5 low minima, the only survivor is 30F on Nov 14th (count 1.0). There were no "coldest since" record low minima.

1906 _ This was generally a warm year with few cold spells, and perhaps the most notable (around March 23-24) failed to set records. Of the 0.83 count of low maxima, none have survived, and of the 1.0 count of low minima, none have survived. There was a "coldest since" record set on Dec 8 when 12F was coldest since the 1882 record of 10F. 1906 was the second year in the data set (after 1890) not to retain any record low maxima. Its extinction date of Oct 11, 1951 was third earliest after 1890 and 1908. Also, 1906 is the third year to have no surviving record lows after 1870 and 1901. It has the third earliest extinction date for those, coming on Dec 7, 1926, and also 1908 set no record low minima so was first "out" in that regard.

1907 _ While this was mostly a rather average year, May and June were very cool and set numerous low records. All of the count for 1907 occurred in these two months. From 4.5 low maxima, the eventual count remains 2.0. And from 6.0 low minima, the eventual count is 3.70. There were no "coldest since record low" minima in 1907.

The closest any minimum of 1908 came to an eventual record low was 5 deg (also Aug 29). Meanwhile, the year set 2.83 record low maxima, of which none remain as eventual records.

1909 _ Although the year had some warmer spells, when it did turn cold it seemed easy to set records even if the cold spells were brief. There were 8.0 low maxima of which 2.53 have survived, and 2.83 low minima of which one remains. There were no "coldest since record low" minima (at least, none that are now valid, all of these years with no valid coldest since minima had a few for some period of time).

1910 _ Cold weather was rather infrequent in 1910 so the counts for record lows were held down below expectation (now having dropped to about 9 records per year, 366/42). From five record low maxima, none have survived, the extinction date being July 18, 1962. The one record low minimum set has been retained (1 F on Feb 7). In addition there was one "coldest since" a record low minimum, that being January 5th 5 F (later tied by 1920) after the -4F record in 1904.

Summary of records set in the decade 1901-10

This was not a prolific period for record cold. Not one year produced the random expected number of minimum records, and only one (1907) retained more than one would expect at random (3.7 vs 2.4). 1903 had a prolific production of low maxima. In the decade, there were 58.0 record low maxima set, of which 20.283 have survived. A few of those set replaced earlier values from this decade so it was not quite a case of 53 starter records falling. Then from 30.92 record low minima, just 11.7 have survived (35.7%). The number of coldest since values is 5.7, bringing the cumulative total to 35.93. 

 

__ Log of Record Lows 1911-1920 __

 

1911 _ Despite several very warm intervals including most of the early summer, as well as December, 1911 also produced a robust set of low records. There were counts of six of each type set during the year. Five of the six low maxima have survived. This is the second highest survival rate (83.3%) for any year 1869 to 1916 (1878 had 87.5%). Only 1.833 record low minima have survived. There was also one "coldest since" a record low minimum, on May 3rd, when 37F tied 1877 as coldest since the record set in 1874 (33F). (count 0.5)

1912 _ This was quite a cold year with a few warmer interludes, most notably the last two months of the year. January 1912 was one of the coldest months in the region generally. Parts of the summer were also anomalously cool.  Despite that, only 2.5 low maximum records were set, of which only 1.0 has survived (8F on Jan 13th). The count of record low minima was considerably larger at 5.75 which is closer to the random expectation now having fallen to 8.3 (366/44). Of those, 1.833 have survived One later tied in 1914 was also on Jan 13th. September 30th (39F, also lowest for month) remains untied, and August 5th (57F) has been tied twice. In addition there were three "coldest since" record low minima during the year. These were on Jan 6th (6F later tied in 1996 and 2018, coldest after record of -2F set in 1896), -1F on Feb 11th (coldest since joint record of -2F in 1885 and 1899), and Aug 4th (57F later tied by 1951 and 1964, coldest since 1886 56F) for a count of 1.667 for the statistic.

1913 _ 1913 was a relatively warm year that set numerous warm records for its time, many of them later broken however. Cold spells were brief and only two low maximum records were set, 20F on March 7th which has survived, and a third tie of an earlier record (39F) on Nov 11th which was later broken. The counts for low maxima were therefore 1.33 and 1.00 (surviving). From 4.5 low minimum records only one (May 11th, 36F) has survived.  In addition there were three "coldest since" record low minima during the year. These were on Mar 7th and 8th (both 12F coldest since 7F in 1890 (this 12F tied in 2007) and 8F in 1883, untied since), and also 45F on Sept 15th, coldest since record of 44F in 1873. (count 2.5) ... There was also a reading of 47F on Sept 14th which was the coldest minimum between tied record lows of 46F from 1911 and 1975 and colder than any others on that date besides those two tied records.

1914 _ Some parts of 1914 were quite warm but record breaking cold was frequent especially in the winter, again in June-July, and December. From a count of 7.0 low maxima, 2.67 have survived. More impressively, from 14.75 record low minima, 8.83 have survived. Both of those counts have not been equalled since 1914, the original count (14.75) ranks 11th behind ten starter era years, but with the expected number down to 7.9, it was ahead of several of those in terms of ratio to expected (although two more recent years have higher ratios, 1940 and 1963). The more recent year with the closest number of eventual record low minima is 1919 (7.0) with 1963 at 6.5. There was also a large count of "coldest since" record lows, with eight producing a count of 5.0. That is the highest such statistic so far although it will be surpassed by numerous later years, the first of them 1933. The "coldest since" record low minima are listed below:

1915 _ This was a rather wet year, somewhat cool throughout, but not often into record low range except for spells in late May-early June and again in late August which were particularly cool. From a count of 2.75 record low maxima, only 1.5 have survived as eventual records (or tied). From a count of 4.67, another 1.25 record low minima have survived.  In addition, there were two "coldest since" record low minima, as shown below, with a count of 1.5:

1916 _ Another year of extremes, for example a very mild January was followed by quite a cold February-March, then a chilly June followed by a warm to hot summer; this  year produced a fairly healthy crop of record low values. From 9.5 record low minima, the eventual count was 3.83. That original total was not exceeded in any later years with 1940 closest at 8.0. From the original 5.5 record low minima, 2.0 have survived to the end. In addition, there were two "coldest since" record low minima, with a count of 1.5. These are shown below:

1917 _ This was always a rather cool year with the brief exception of a four-day scorching heat wave July 29 to August 1, but the autumn and early winter turned progressively colder relative to normal and ended up with a record-shattering week that extended over New Years into early January 1918. During that interval NYC had its lowest maximum and second lowest minimum on Dec 30th (2, -13). Feb 9, 1934 was -15F. As noted elsewhere a colder day than these might have occurred on Jan 22nd, 1857 before the Central Park records began. During the year, there were 8.83 record low maxima (the highest value for any year 1917 on, with 1940 at 8.0) of which 7.0 have survived. That number of eventual records is also highest for the interval 1895 to present, and ranks tenth behind nine starter era years. It was also a better survival rate than any year so far except 1878 and 1911, and the best survival rate for any year that set more than eight records. From the original 8.167 low minimum records, 6.33 have survived. That is slightly behind 1919 (7.0) and tied with 1926, as second highest after the 1914 production of 8.83 (see 1914 discussion for where that ranked relative to previous years). In addition, there were seven "coldest since" record low minima, with a count of 5.0. These are shown below:

1918 _ The severe cold continued for much of the winter of 1917-18, and June 1918 was also quite a cool month. The summer became rather hot by mid-July and August. The autumn was generally rather warm. From 7.0 record low maxima, 6.0 have survived. No year since has had that many (1963 had 5.33). It was also the second highest survival rate for years before 1919 (that year was higher as was 1925, before the more modern tendency for 100% survival to be fairly common). The low maximum for Feb 4th was a monthly record also. Of the 8.33 record lows set, 6.0 have survived. Only 1919 and 1926 have had more since then. In addition, four minima were "coldest since" record lows, with the count 3.33, as shown below:

1919 _ A few portions of this year were quite warm but it had enough cold spells to give potential for a robust total of surviving records. Although the count of low maxima was only 3.83 (and random expectation has now fallen to 7.1), the surviving count of 3.5 produced the highest yet survival rate of 91.3%. This would be broken in 1925 (95.5%). The count of record low minima was 9.5 of which 7.0 have survived, this being the highest total from 1919 to present day. There were no "coldest since" record low minima in 1919.

1920 _ This was a rather variable year, the coldest portions relative to normal were in January and June-July. Only three low maximum records were set, two of which remain as eventual records. The count for record low minima was considerably higher at 11.083 (higher than any later year in the series), of which 5.5 have survived. There were also six "coldest since" record low minima with a count of 3.25, details below:

Summary of records set in the decade 1911-20

The pace of record setting picked up for cold with several years well above average in eventual record production, even though the number set during some of those years was slightly below expectation at random, which fell to just over seven by 1920. The total number of low maxima set during the decade was 51.75, of which 33.5 have survived. The first of those stats is below random expectation while the second is above by almost half. There were 78.25 record low minima, close to random expectation (77.3) and of those, 41.58 have survived. That brings the total from 1869 to 1920 to 202.48. That indicates about 180 cases that could have a "coldest since" (as later ties would be excluded) and during the decade there were 24.25 of those, for a total so far of 60.18 set (about one-third of the possible total).  

 

 

__ Log of record lows 1921-30 __

 

1921 _ This was a relatively warm year without significant cold spells, and the production of cold records was low. From a total of four record low maxima, one has survived. And there was just one record low minimum which was extinguished on Aug 15, 1963. Thus 1921 becomes the fourth year to retain no record low minima (joined 1870, 1906, 1908). The production of 1.0 during the year was tied second lowest so far (1908 had zero, 1906 and 1910 also had 1.0). There was also one "coldest since" a record low minimum, with 7F on Dec 22nd the lowest reading after the record of 4F set in 1872.

1922 _ Although not as warm as the preceding year, the pace of record lows did not change. There were only two record low maxima, neither of which survived, and the extinction date was Aug 12, 1979. From an original count of 3.5 record low minima, 1.0 has survived. There were also four "coldest since" record low minima, with two ties, the count is 3.0. The details are below:

1923 _ After a fairly average winter, March turned very cold near the end and record cold lasted to about April 2nd. Most of the record lows of 1923 took place in that cold week as shown in the tables below. Another very cold interval occurred around May 9-11. Two records were set on July 31 and August 1 although much of the summer was otherwise quite hot. From four record low maxima, 3.0 have survived. Also from 7.33 record low minima, 5.0 have survived, including the lowest temperature for April (1st, 12F). In addition, there were seven "coldest since" record low minima, with a count of 4.417.

1924 _ Generally a rather cool year, 1924 produced about as expected at random (now down to 6.5 from 366/56) but its records were fairly robust. From 5.5 record low maxima, 3.67 have survived (random for every year is 2.4 for surviving records). May,  June and November were the coldest months. There were 9.5 record low minima, of which 3.83 have survived. In addition, there were six "coldest since" record low minima and a count of 4.583 as shown below:

1925 _ Some brief cold spells were interspersed with warmth to September, then October turned very cold. This trend faded out with a few minor resumptions in December. The year set 3.5 low maxima and retained 3.33, with just a later third tie of one record (Oct 29, 1952) preventing 1925 from becoming the first year in the series to achieve a perfect survival rate, even so it was the highest percentage so far at 95.3%. There were 9.5 record low minima, of which 5.67 have survived. In addition, there were six "coldest since" record low minima and a count of 3.83 as shown below:

* Mar 3 1925 (11F) tied five times later, in 1938, 1943,1950,1962, 2003. This is the only current six-way tie for a NYC temp record. 

* Also the reading of 15F in 1912 was a tie of three other years, 1873, 1888 and 1890.

 

 

1926 _ This was a notably cold year in general. Parts of the summer and autumn into early winter were particularly cold. From 5.83 record low maxima (only around the expected number of 6.4) 3.0 have survived. There were 9.67 record low minima from which 6.33 have survived; only 1963 (6.5) has a higher total since. The yearly count  of 9.67 was higher than all years except 1940 (10.5) since 1920 had 11.083. There were another three "coldest since" record low minima and a count of 2.5 as shown below:

1927 _ This was another rather cold year in general and the summer in particular was very cool. From the count of two low maxima, none have survived and the extinction date for those was June 30, 1967. There were 3.83 record low minima of which two have survived (Jan 27th and June 16th). In addition, there were two "coldest since" record low minima, and two significant between-tied-record-minima next coldest values as detailed below:

1928 _ Temperatures were slightly closer to average than previous years, and there were just 2.83 record low maxima, of which one (later tied) has survived for a count of 0.5 -- this is the lowest survival rate (17.7%) of any year that had any eventual record low maximum records (only eight years have zero survival rates from some number of records set, and 23 others set no records). If any records from 1893 are tied or broken then it could fall lower (from 20.9%) as it already did in March when 2022 replaced one of its records to get to that second lowest value. The year had 2.75 record low minima of which 1.5 have survived. Also, there were two "coldest since" record low minima, one of which was tied in 2020 so the count for those is now 1.5.

1929 _ The year had a very small production of record low maxima, with just two tied results for a count of 0.83 and 0.33 surviving. There were 6.33 record low minima of which 3.53 have survived. Four "coldest since" record low minima gave a count of 1.917, and there was one other significant lowest value between tied record lows.

1930 _ With a very mild February and a hot summer, opportunities for record cold values came mostly in the spring and autumn, although later August was also rather cool. From 2.0 record low maxima, 1.5 have survived. And from 5.83 record low minima, 5.33 have survived. That survival rate of 91.4% was second only to 1910 to this point in the data (100% but from just one survivor). High survival rates became more and more common after the next 100% case in 1932 (which preserved all of its 3.5 count). The first year to preserve all records with a higher count than 1930 was 1976. Only 1940 (5.5), 1963 (6.5) and 1976 (6.0) had more surviving low minimum records than 1930 in the interval 1927 to 2021. There were also two "coldest since" record low minima as detailed below:

Summary of records set in the decade 1921-30

The pace of record setting was generally only somewhat lower than the previous decade since totals are judged against lower expectations, as the number of records expected by 1930 was 5.9, and the decade average was 6.5. Slight declines in totals from the previous decade would therefore be expected (for records set during years, the number of surviving records is always constant at 2.4 per year). From a total of 34.5 low maxima set, barely half the expected number, the number of survivors is 17.58.  The total number of low minima set during the decade was 60.25, of which 34.7 have survived (random expectation for that is always around 24 per decade). The decade had a total count of 26.75 "coldest since" record low minima, and the total count so far is 87, against a total of 237.2 record low minima. Since some of that count would involve later ties, which would remove years to 1930 from being eligible to set "coldest since" records, the ratio is more realistically 87.1 for about 200 or so. So what we can conclude is that by 1930, about one quarter of dates had seen both their record low minima and the coldest value that would occur thereafter. Another quarter to third of dates had seen their record lows but not yet the coldest since. And about 40% of dates had not seen their record low yet by 1930, or at least had a tie of an existing record low yet to occur. 

 

__ Log of Record Lows 1931-40 __

 

1931 _ This was generally warm year with few days below normal, let alone close to record cold values. An interval from May 12 to 14 is shown but none of these cool readings were quite records. From the one record low maximum set on August 11th, the eventual count is 0.33 after that was tied in 1933 and again in 1962. The count of one record low maximum was third behind 1906 and 1929 (tied at 0.83) so far; the first year to have no record low maxima was 1936. There was only a count of 0.5 record low minima (May 23rd, tied 1929) which only survived to May 23, 1935; only 1908 (no record low minima) had a lower total within the year to this time, and only 1870, 1901, 1906, 1908 and 1921 had zero survivors before 1931 joined the list. Of those, 1870, 1901 and 1906 had earlier extinction dates and were all at zero before 1931 started (1908 had none to go extinct). Also, there was one "coldest since record low" value for minima, as shown below:

1932 _ This was a somewhat colder year once the record warm January and mild February had run their course. March had some quite cold days that are shown in more detail as several near-records occurred as well as one actual one. There were brief cold spells otherwise, and July was rather cool but set no records. Nov 27th was a particularly cold day but the cold was not sustained and it was very mild late in December. From only 1.5 record low maxima, the surviving count is 0.5. From 3.5 low minima, all have survived, making this the first year to achieve that status (100% survival rate). The tied record (Nov 27th) equalled a mark set earlier in 1898, otherwise the three records are all in the spring to early summer. In addition, there were two "coldest since" record low minima, and a count of 0.83 for those:

1933 _ The first two thirds of this year were relatively warm with only limited opportunities for record breaking cold. The autumn and December were more variable and had frequent cold spells. What kept the count down somewhat was that 1933 tended to follow the path of earlier extreme years for cold rather than hitting easier stretches where its temperatures would have set more records. Some of these near misses are added to the table. From a count of 4.0 low maxima, the eventual count was 2.33. Then from 6.083 record low minima, the count was 3.5. There were nine "coldest since" record low minima, and a count of 6.533 for that statistic. This is the highest count so far and later surpassed only by 1940, 1967, 1976, and 2018 (thus in 5th place overall).

1934 _ The severe cold of Nov-Dec 1933 relented in January but returned at the end of the month and lasted all through February and parts of March. This set a number of records including the lowest minimum temperature (-15 F) of the data series on February 9th. Temperatures in upstate New York were below -40 in this extraordinary outbreak, and Toronto also had some of its lowest temperatures in a longer data set. The rest of 1934 became rather warm and some parts of the summer were extremely hot. Overall, this led to a total of 3.5 record low maxima, all of them retained at the end of the data. This was the first year to manage the perfect survival of its record low maxima (1910 had done it for low minima). It would happen numerous times later since those records were more and more unlikely to be broken. Also, the year set 5.75 record low minima (now higher than expectation as that had fallen to 5.5); 3.5 of those were also eventual record lows. There were seven "coldest since" record low minima, which had a count of 5.17 for the year. Details of those follow:

1935 _ This was overall a rather average year with a fairly equal distribution of warm and cold spells. It held a similar status to 1934 in preserving all of its 4.0 low maximum records until 2019 tied Jan 31st (16F) and reduced the survival rate to 87.5% (3.5). There were only 1.5 record low minima, of which none have survived. The extinction date was Oct 8, 1988. There were also three "coldest since" record low minima, with the count 2.5, details below:

1936 _ Most remembered for its record-breaking 106F reading on July 9th, there were some other warm spells in May, August, September and December, but quite a few rather cold spells. Despite that, 1936 became the first year not to set a low maximum record during the year. At that point, The closest readings to records (and all but the last mentioned instance of this still applies) were 29F on Nov 27th, one degree above the tied record of 28F (1898, 1932), and two instances of a 2F miss (18F on Feb 19th, record 16 from 1903, and 66 on June 13th, record was 64F from 1875, 1924, later fell several times ending up 55F in 1982). In 1936, none of the earlier years that would reach extinction had done so, 1890 would join it in August, 1937, and 1939 also set no low maxima, while 1908 went extinct in 1940. 1906, 1910, and 1922 went extinct later. The year was far more productive in low minima, setting a total of 6.167 records of which 5.0 have survived. At random by 1936 we can expect 5.4 records per year (2.4 survivors). There were also six "coldest since" record low minima with a count of 4.083, details below:

________________________________________

* The Feb 18-19 sequence looks odd, but apparently what happened was that a cold front arrived early Feb 18, dropped temps steadily to the evening hours, a minimum of 1 F was reached, then by midnight it was 9 F, began to snow a little during this weak warming phase, and another shot of colder air arrived so the max on 19th stayed low at 18F. (from historical weather maps).

 

 

1937 _ The  year started mild and then became more average with few large departures from normal in either direction. From only 2.5 low maximum records, 0.83 is the count for surviving records. From 1.2 record low minima, none have survived. The extinction date was September 18th, 1990. Also there was just one "coldest since" a record low, with the count 0.5 as that was tied. Details follow: 

Coldest since _____ 1937 value __ tied by ___ count

Oct 15, 1876 (32F) _____ 34 ______ 1877 _______ 0.5

(in addition, 58F on July 2nd tied with 1940 and 1988 as coldest between tied record lows of 56F in 1888 and 2001)

(also 38F on Oct 9th was tied with 1895 as the coldest reading between tied records of 37F in 1888 and 1988 and that equalled the "coldest since" value in 2000).

1938 _ This was a generally warm year, the only significant cold spells came in late June and again in late November after a warm start to the month. The count of record low maxima was just 2.5 with 2.0 surviving. There were 4.33 record low minima, of which two have survived. There were also three "coldest since" record low minima, with the count 2.5, details below:

** Mar 3 record low min (11F) eventually a six-way tie 1925, 1938, 1943, 1950, 1962, 2003. 9F on Mar 4th 1938 was not a record low (6F 1872) nor a "coldest since" with 7F in 1943.

 

1939 _ This was a more average year for temperatures, often rather close to average, 1939 became the second year to have no record low maxima (after 1936) and its closest approach was three degrees (52F May 13th, record was then 49F from 1914, is now 48F from 2019). There were just two record low minima with an eventual count of 0.33. The year had just one "coldest since" record low minimum, since tied, for a count of 0.5. Details below:

1940 _ This was a colder year that was similar to 1917 and 1926. Cold spells were frequent and sometimes quite prolonged. April and October were particular cool months and the summer while it had a few hot days was often quite chilly. From 8.0 low maxima, there were 5.0 surviving records. The count was the highest since 1917 (8.83) and has not been surpassed since 1940, while the eventual count was the highest since 1918 (6.0), and second only to 1962 (5.33) while tied with 1945 for years after 1918.  From a count of 10.33 low minima, there were 5.5 surviving, again both higher than all years after 1920 (count 11.08) or 1926 for survivors (6.33) except for 1963 (6.5) and 1976 (6.0). The expected number of records within the year has fallen to 5.1 (surviving always 2.4). In addition, 1940 had nine "coldest since" record low minima for a count of 7.25, higher than all following years except 1967 and 1976 (tied at 9.583). It was also in third place overall as it overtook 1933 with 6.53. Details below:

Summary of records set in the decade 1931-40

The pace of record setting was heading considerably lower until 1940 brought it back up into almost the range of the previous decades. From 27.0 daily low maximum records, 18.0 have survived. At random there were expected totals of about 55 and 24, so these are both below expectation, especially the raw numbers. For low minimum records, 40.03 records in total generated 23.33 eventual records. These are both closer to random expectations.  The decade had a total count of 30.867 "coldest since" record low minima, and the total count so far is 117.8, against a total of 260.53 record low minima. Since some of that count would involve later ties, which would remove years to 1940 from being eligible to set "coldest since" records, the ratio is more realistically 118 for about 230 or so. With 1940 close to the halfway mark of the data (currently that would be mid-1945) over two thirds of the days of the year had seen at least some if not all tied eventual record low minima, but only one-third had seen the coldest since that record (a few because there would be a later tied value). 

 

 

__ Log of Record Lows 1941-50 __

 

1941 _ This was a generally rather warm year but March was quite cold, and there were brief cold spells at some other points. March did not manage to set any records, the 17th had a maximum of 28F but that was four above the 1916 record. The records set (in the summer despite generally warm weather) were few in number. From a count of 2.0 low maxima, none have survived. The extinction date was July 4, 1978. Also, the 1.0 record low minimum in August did not survive. The extinction date was August 14, 1964. 1941 thus became the fourth year to have no surviving low records, either maximum or minimum. 1906 had already reached that status in 1940 and 1908 would do so in 1951 (but after 1944). The next year to go "extinct" in both categories would be 1944 which lost its only record (a tied minimum) the following year (June 5, 1945). Otherwise there are seven others all after 2000. So 1941 had become the fourth such year before any of those happened (some set no records in either category). There were also two "coldest since" record lows with a count of 1.33. Details follow:

1942 _ This year turned quite cold at times, particularly December. It was not, however, a prolific producer of cold records. From a count of 2.0 low maxima, one (April 10th) has survived. Also, the 2.33 record low minima have left 1.33 survivors (notably Dec 20th). There were also three "coldest since" record lows with a count of 2.33. Details follow:

1943 _ The winter of 1942-43 continued rather cold and there was one more very cold day (Feb 15th) which produced low max and min values not surpassed since (8, -8). The spring was also quite cold, while the rest of the year became more average after a very warm June. There were 3.5 record low maxima, with the count 2.167. The count for record low minima was 3.33, with the eventual surviving number 3.167. In addition there were four "coldest since" record low minima, with the count 3.0. Details below:

1944 _ 1944 was generally quite a warm year and produced almost no record lows. There were no record low maxima (the third such year after 1936, 1939). The closest approach (valid in 1944 and in the first two cases still valid) was within 3 F deg on April 15th (44F), April 24th (47F), and June 4th (67F) -- the last of these was removed from that stature the next year when 1945 blew away the record with 52F. For record low minima, the count is a mere 0.5, achieved by a tied record on June 5th which was extinct the following year (June 5, 1945). There was just one "coldest since" record low minimum that has three ties for a count of 0.25. Details below:

1945 _ After some cold weather in January, the spring turned very warm, with a return to colder weather during May. The interval from June 1st to 6th was exceptionally cold and set many records including a tie of the monthly low maximum (52F) and the monthly low minimum (44F). The rest of the year was closer to average in general, although sometimes rather cool, and December turned quite cold again but only came within 3 or 4 degrees of existing record lows. From a count of 5.5 record low maxima, 5.0 have survived. In years since 1945, only 1962 has more surviving record low maxima (5.33). The count for record low minima was 4.25, which was only reduced to 4.20 eventually when 1946 joined what had been a four-way tie for the record on June 2nd. In addition, there were four "coldest since" record low minimum values, for a count of 2.167. Details follow:

1946 _ This was a warmer year with only brief cold spells. The counts for record low maxima were 2.0 both original and eventual shares. This was the second year to achieve 100% survival of its records to the present time. There were just 2.2 record low minima of which 1.2 have survived. Also there were two "coldest since" record low minima, details follow:

1947 _ Jan-Feb 1947 had a rather average winter, while Europe had very cold weather (especially February), but that cold appeared in the spring in NYC and left quite a few records, two of which fell in May, 2020, so that the count is not as impressive for surviving low minima as it was before (it was 6.5). Another very cool interval was late September before a record warm October. There were 3.33 low maxima with just 1.33 surviving. However the year produced 8.0 low minima and a count of 4.5 has survived. In addition, there are three "coldest since" low minima with a count of 2.0; details follow:

1948 _ Most of this year was quite warm and when intervals were cold they rarely went close to record temperatures. There were two tied record low maxima for a count of 0.83, of which the surviving count is 0.50. There were no record low minima set during the year. This was the second such year after 1908. The closest approach to a record low minimum was Jan 31st when 0 F was one degree above the 1920 record of -1F. However there were four "coldest since" record lows with a count of 2.33. Details follow:

1949 _ This was a very warm year and quite often dry. Record lows or even below normal temperatures were very infrequent and rarely sustained. There was one tied low maximum which was 74F on July 17th, and this both tied 1873 and was further tied in 1962 before the extinction date of July 17, 1992 (72F). 30F on Nov 27th was not a record (28F in 1898, 1932) but is now tied with July 17th as being closest to an existing record low maximum in 1949. The count of 0.5 was fourth lowest so far, after three years with no record low maxima (1936,39,44). The production of record low minima was equally sparse, with one record but that has survived (55F on August 20th). There were also two "coldest since" record low minima, with a count of 1.25.

1950 _ January continued the previous year's trend of warmth, but colder months followed and April, 1950 was quite chilly. A few days in the summer and early autumn were cold, but from October to December it was once again often warmer than average. From just 1.5 record low maxima, the count was 1.17 for surviving records. From 5.45 record low minima, the surviving count was 2.17. Only 1963 (7.5) and 1976 (6.0) would have more record low minima in years remaining. By 1950, the random expectation was 4.5 records. There were were three "coldest since" record lows with a count of 2.5. Details follow:

Coldest since _____ 1950 value __ tied by ___ count

Summary of records set in the decade 1941-50

The pace of record setting continued to fall further behind random expectation in both temporary and eventual cold records. From 21.17 daily low maximum records (47 expected at random), 13.33 have survived (24.1 random). For record low minima, 27.57 records resulted in an eventual count of 17.07. The decade had a total count of 19.17 "coldest since" record low minima, and the total count so far is 137, against a total of 277.6 record low minima. Since some of that count would involve later ties, which would remove years to 1950 from being eligible to set "coldest since" records, the ratio is more realistically 137.3 for about 245 or so. About 60% of record lows (some not yet fully set) still have a "coldest since" in the future as of 1950. The pace of this statistic will remain modest in the 1950s but will pick up considerably after 1960.

 

__ Log of record lows for 1951-60 __

 

 

1951 _ This was a generally rather warm year with limited cold spells, the most significant in mid-June and early November. There was only one record low maximum, 48F on October 11th, and this has survived to the present. It makes 1951 the third year to have full survival of its record low maxima (after 1934, 1946). The closest candidate for a second low maximum was Dec 16th with 20F, just one degree above the 1886 record. From 1950 to 1980, all days within 1F of a record low (of either type) will be listed (some minima will also appear in the "coldest since" table) as it could be argued that the urban heat island makes them climatologically equivalent if not more likely in the absence of the heat island. This criterion will be raised to 2F for 1981-2022.  June 14th (61F) was two degrees above the 1907 record (and min 53F four degrees above a record), and June 30th (71F) a similar differential of 2F but that would increase to six degrees in 1967. The year also had only three record lows for a count of 1.83, and the eventual outcome of 0.33 (56F on Aug 5th tied two earlier years). The low on Aug 4th was also both a "coldest since" and within 1F of the 1886 record.  Aug 6th (58F) came within two degrees of the record low minimum, as did Sep 8th and 30th (see below). There were seven "coldest since" record lows, for a count of 4.833. Details follow:

1952 _ This was a rather warm year also, apart from October which was generally quite cold. The record lows in June preceded some record heat and this is as close as record lows and record highs have appeared in the NYC data. From 2.17 record low maxima, the eventual count is 0.83. May 20th (54F) was within 1F of the existing record but that increased to 3F in 1957. There was one record low minimum during the year, a tie with 1940 producing a count of 0.5 -- this has not survived and the extinction date was Oct 20, 1972. No other maxima or minima were within 1F or 2F of existing records. There was just one "coldest since" a record low minimum:

1953 _ Despite being one of the warmest years on record, 1953 managed a few record cold days. There were two record low maxima, each tying a previous mark, and one has survived (counts 1.0 and 0.5). There were two record low minima and both have survived. That makes 1953 the fourth year so far to manage 100% retention of its record low minima. In addition, there was one maximum within 1F (on May 30) although that has since risen to six degrees above a new record set in 2021. The maximum noted in the table for June 13th was two degrees above the existing record (then 61F in 1941) and later rose to eight by 1982 (55F). Also there was a minimum on Oct 8th one degree above the existing record, now three above a later record. There was one minimum on Aug 2nd (59F) two degrees above the record low (57F in 1875) and not a "coldest since" as that had been taken by 1924 with 58F. And there were two "coldest since" record low minima, with the count 1.5. Details below:

1954 _ The warm trend continued with brief interruptions. January (although not setting records) and then late March into early April were quite cold, and parts of September also set records. Most other months were warmer than average if only slightly. There were two record low maxima (count 2.0) of which one (Sep 15th, 57F) has survived (count 1.0). Dec 7th (28F) came within two degrees of the 1869 record low maximum. The previous day (25F) had been three degrees above the record value. From three record low minima with a count of 2.5, the surviving count is 1.5. The minimum of 59F on Aug 11th was two degrees above the record low minimum. In addition there were three "coldest since" record low minima, with no ties for a count of 3.0, details below:

1955 _ The last of an eight-year warm spell (1948-55), the year recorded no record low maxima, and just one record low minimum which has survived (counts 1.0). With that one record low on Feb 3rd, the maximum (17F) was within 1F of the record (16F, 1917).  June 9th (58F) was also within 1F of the 1916 record of 57F and the minimum (51F) was also 2F higher than the 1913 record. On Dec 22, the maximum of 22F was within 2F of the record set in 1921, but later with a new record in 1989 (18F), this rose to 4F. June 26th had a minimum of 58F, 2F above the record. Sep 8th and 15th were also 2F above existing record lows (the 15th would later fall to lower values). In addition (including Sep 8th and Nov 29th) there were three "coldest since" record low minima for a count of 2.17.  A coldest since (8F) shared with 1996 was removed on Feb 4, 2023 by a colder reading in 2023 (3F) after the record low (0F) set in 1886 and 1918.

1956 _ The year turned somewhat colder than previous years, with occasional warm spells, but quite a few chilly intervals that sometimes got into record range. The spring and summer were particularly cool relative to normal. July 6th (max 61F) was the coldest July daytime high and had one of the largest margins over second coldest (10 F deg). From 3.5 low maxima, 2.33 have survived. In addition, seven days, May 17th (54F) and 18th (55F), June 20th (66F), July 5th (64F), Aug 20 (72F)* Sep 28th (57F)* and Nov 10th (40F) had maxima within 2F of records (the two marked * of these changed to 4F with lower records in 1990 and 1984). And from 3.33 low minima, 2.0 have survived. The low on May 8th (37F) was within 1F of the 1947 record and has slipped to 2F after 2020 set a lower mark. Lows on May 24th (44F) and 25th (42F) were also within one degree but the first of those later rose to 5F above the new 1963 record. The minimum of 58F on July 31st remains 1F above the tied record values. The low of 41F on Sep 21st remains 1F above the 1871 record. A low of 29F on Nov 11th was 1F above tied record lows but this changed to 5F in 2017. In addition, six "coldest since" record low minima produced a count of 3.17, details follow:

1957 _ This was a somewhat warmer year than the previous one and more similar to the early 1950s again. There were only 2.0 low maximum records with 1.5 surviving. The maximum of 47F on Oct 26th was within 1F of the record but that changed eventually to 8F after a much lower value in 1962. And from 1.5 record low minima, the entire 1.5 have survived (the fifth such year so far). The minimum of 57F on Aug 6th was 1F above the 1869 record. A low of 29F on Nov 11th was 1F above tied record lows but this changed to 5F in 2017. Also, the minimum of 40F on May 4th was within 2F of the record and qualified as a "coldest since" those tied records. The low of 45F on May 20th was within 2F of tied 1907 and 2002 record lows. The low of 51F on June 9th was also 2F above the 1913 record but that slipped to 4F in 1980. The Sep 28th low of 43F was 2F above the 1947 record (also a "coldest since"). And the Oct 28th low of 35F was within 2F of the records, which changed to 6F in 1976. In addition, there were four "coldest since" in total with a count of 2.33; details follow:

1958 _ This was quite a cool year in general, with 5.0 record low maxima of which 3.5 have survived. Feb 17th had a maximum of 10F which was three above the 1896 record for that date. May 6th (46F) was one degree above the 1891 record and May 15th (51F) one degree above the 1878 record. And 74F on July 14th was only one degree above the tied record of 73F, while 43F on Nov 2nd was two degrees above the record low maximum (41F) from 1875 and 1895. Despite all that, there were no record low minima in 1958. Two now qualify as closest at 2F above existing records. This was the third such year after 1908 and 1948. The low of 39F on Oct 14th was within 1F of a tied record of 38F but that changed to 2F in 1988. The minimum for Feb 18th (3F) was within 2F of the 1896 record but slipped to 3F in 1979. Also the minimum of 29F on Apr 9th was within 2F of the existing record (1885, 1950 tied 27F) but that changed to 4F when 1977 went lower to 25F. The minimum of 49F on June 7th remains 2F above the 1879 record low. There was just one "coldest since" a record low minimum as shown below:

 

Coldest since _____ 1958 value __ tied by ___ count

(In addition, 3F on Feb 18th was the coldest reading after the 1896 record of 1F until 1979 hit zero to create a new record low.)

1959 _ This was generally quite a warm year similar to 1955. There were only two low maximum records set, one a second tie of an earlier record, both having survived (counts for both 1.33). The maximum of 65F on June 16th was also one degree above the existing record but that changed to 3F when 1965 had a lower record value. July 14th (74F) was also 1F above the record low max set in 1884 and tied three times since 1960. Aug 5th (70F) was two degrees above the 1903 record. There was also one low minimum  record for a count of 0.5. That record was broken on Sep 17th, 1986. Also the minimum on May 16th (43F) was one degree above the 1878 record. A low of 53F on June 17th was 2F above the 1926 record. The count for seven "coldest since" record low minima was 4.083.

1960 _ This was a colder year again, although not as extreme as some in the 1920s or 1930s. March and December were notably cold months. From 2.5 record low maxima, 1.25 have survived. In addition, March 3rd (27F), March 10th (30F) and March 26th (36F) were all one degree above existing record low maxima, although March 10th slipped to 2F above the 1987 record. 71F on Aug 19th remains 1F above the record (1881,1946 tied 70F). Aug 5th (70F) was two degrees above the 1903 record, and Nov 7th (43F) two degrees above the record (four years tied). Also, from 4.0 record low minima, 3.0 have survived. The minimum of 30F on Nov 8th was 1F above the tied coldest records of 29F in 1886 and 2019. There were no "coldest since" record low minima, the first year since 1919 without one. The next would be 1966.

Summary of records set in the decade 1951-60

The decade had very similar totals to the previous one for daily low maxima, and smaller outcomes for daily minima. From 21.5 daily low maximum records (42 expected at random), 13.25 have survived (24.1 random). For record low minima, 17.17 records resulted in an eventual count of 11.33. The decade had a total count of 22.58 "coldest since" record low minima, and the total count so far is 159.55, against a total of 289 record low minima. Since some of that count would involve later ties, which would remove years to 1960 from being eligible to set "coldest since" records, the ratio is more realistically 159.55 for about 260 or so. More than half of record lows (some not yet fully set) still have a "coldest since" in the future as of 1960. The pace of this statistic will pick up considerably after 1960.

 

__ Log of record lows for 1961-70 __

 

1961 _ This was a rather average year for temperatures, sometimes rather warm especially autumn. The only prolonged cold spell was mid-January to early February and it was more of a sustained than a record cold. May 27th was an unusually cold day with another morning low record the next day, but it then warmed up quickly. There were only 1.5 record low maxima, 1.0 surviving (May 27th) and no other maxima within 2F of existing records. There were 2.0 record low minima of which 1.5 have survived. The low of -2F on Feb 2 was only one degree above the 1881 record for the date, and for May 31 (47F) there was also a one degree differential. On June 16th the low of 54F was two degrees above the 1927 record, as was 57F on Aug 14th (changed to 3F above in 1964).  In addition, there were five "coldest since" record low minima, none of them tied for a count of 5.0.

1962 _ This year combined some warm spells with prolonged intervals of cold. The summer months were notably cool, especially mid-August. Early May was cold and then warmed to record heat around the 18th-20th. From 6.67 record low maxima, 5.33 have survived, the highest totals in either case this late in the data set (highest since 1940 for records in year and 1918 for records surviving) . Sep 5th (63F) was also just one degree above the 1926 record low maximum. It was rather cold in mid-December with three days within 4 deg of record lows. A maximum of 13F on Dec 31st and minimum of 4F while not close to the 1917 records are the lowest readings on that date since the records were set. By contrast there was only a count of 1.2 record low minima, 1.167 surviving. The minimum of 57F on Aug 10th was only one degree above the record low  and, like the minimum of 57F on July 27th which was only 2F above the 1920 record low, both were a "coldest since" while another 2F differential on Aug 9th came between tied record lows. Minima of Sep 20th (47F) and 21st (42F) were both 2F above existing record lows and 31F on Nov 7th was also 2F above the 1930 record  ...  There were seven "coldest since" records for a count of 4.033.

1963 _ Cold spells continued to be frequent and quite robust, especially for overnight lows. The year recorded some warm spells too including a very warm October-November period, but other than late March most of the rest of the year trended below average. Much like 1947 both May and September were cold then a more mixed summer and warm October were added. The winter of 1962-63 was severe in Britain but could best be described as moderately cold in eastern North America.

There were 3.33 record low maxima which left 3.25 eventual records when one was later tied. Sep 5th (63F) also came within one degree of the 1926 record. No other days came within 2F of existing record low maxima. There were 7.5 record low minima, of which 6.5 have survived. Those are both the highest totals for any year from 1940 (10.33 record lows), or 1919 (7.0 surviving record lows), to end of the data (1976 came close with 6.0, 6.0). Aug 25th (53F) came within one degree of the 1940 record. Sep 6th (49F) came within one degree of the 1924 record. May 2nd came with 2F of the record low minimum as shown in the "coldest since" table. 54F on June 22nd was also within 2F of the 1897, 1940 tied record and 59F on July 4th although that would increase to 4F after 1986. Aug 11th (58F) also came within 2F of the 1962 record. Aug 19th (57F) came within 2F of the 1924 record and appears in the coldest since list. Sep 14th (48F) was within 2F of the 1911 record later tied in 1975. 

In addition, there were a total of eight "coldest since" record low minima, with a count of 6.33. This is the second highest count so far (1940 had 7.5) and would be beaten by only 1967 and 1976 (both with 9.08), 2018 (6.83) and 1989 (6.5), tying 2000 (6.33).

1964 _ Temperatures were more variable, with brief cold spells mainly confined to the late summer and autumn. From 2.5 record low maxima, 2.0 have survived, both in July. Also,  July 24th (69F) was within 2F of the 1904 record low maximum. From 4.83 low minimum records, 3.5 have survived. Aug 4th (57F) was within 1F of the 1886 record low and Aug 10th (56F) was within 1F of the 1879 record low. Oct 24th (33F) was just 1F above the 1889 record low, but that increased to 2F when 1969 went lower. June 17th (53F) was within 2F of the 1926 record, and Aug 9th (59F) was 2F above the 1919 record later tied in 1989. Aug 20th (57F) was two degrees above the 1949 record low. Sep 14th (48F) was two degrees above the tied 1911 and 1975 record low. Also, Oct 6th (38F) was two degrees above the 1881 record low. 

In addition, from six "coldest since" record low minima, the count was 3.58. Details follow:

1965 _ This was generally quite a cold year with two months that were warmer than average, May and December. July was persistently cool but did not venture into record domain. Late August was especially cold and did set records including tied monthly minima on 29th and 30th (50F) equalled in several other years. There were 4.0 low maximum records, of which 2.0 have survived. Oct 4th (52F) was within 1F of the 1883 record of 51F. In addition, June 15th (62F) was within 2F of the 1916 record (later tied in 1971), and Oct 5th (52F) was within 2F of the 1881 record (50F). There were 2.5 record low minima which have left 1.33 surviving. The minimum of 53F on June 16th was within 1F of 1927 record low 52F, and the next day was also within 2F of the 1926 record (both are among the "coldest since" marks below). July 29th (60F) was within 1F of the 1914 record low, and the low on Oct 29th (32F) was within 1F of the 1925 record while the low of 31F on Nov 2nd was within 1F of the 1887 record. In addition there were eight "coldest since" low minima with a count (after ties) of 4.917. Details follow:

1966 _ The year is most well known for its prolonged summer heat waves, but most of the remainder of the year was either near average or sometimes quite cold, in particular May was a very cool month. There were no record low maxima in 1966 (the fifth such occasion so far), but two days came within 1F of record lows. April 28th (42F) was 1F above the 1898 record, and Dec 3rd (25F) was 1F above the 1886 record (24F) which changed to 2F when 1976 (23F) went lower. From 1.5 record lows, the same count have survived. Feb 20th (8F) was within 1F of the 1950 record low (7F) but this margin changed to six degrees in 2015 (2F). There were no "coldest since" record low minima in 1966 although Feb 20th was one until 2015 eliminated it.

1967 _ After a warm January, it was quite often rather cold in 1967, with June and December somewhat warmer. There were notable cold spells in mid-March and late May. The count for both record low maxima set and surviving is 4.0. This was the fifth year in the data set so far to have a complete retention of record low maxima (it becomes more common after this, with fewer years left to remove any records set, 29 more years appear in the category out of 52 from 1971 to 2022). Four more days were within 1F, Mar 17th (26F), Apr 24th (45F), Aug 13th (69F) and Nov 7th (42F) -- further details in the table.  May 26th (55F) was also within 2F of the 1901,1907 tied records (53F), and Aug 25th (66F) within 2F of the 1873 record of 64F. Sep 23rd (59F) was within 2F of the 1963 record of 57F. 1967 also has a full retention of record low minima, scoring three in both records set and sustained. This makes 1967 the first year to maintain all of its record lows in both low maximum and low minimum categories. May 25th (42F) was within 1F of the 1925 record. In addition there were twelve "coldest since" record low minima, for a count of 9.583, tied with 1976 as highest all-time.

1968 _ The interval from Jan 8 to 12 was very cold and set a number of records. Otherwise, cold weather was rather infrequent in 1968, and it was quite warm in both April and October. There were 3.0 record low maxima, with the count 2.5 for surviving records after one of them was tied in 1970. Otherwise, no maximum was closer than 3F to a record then in existence. From 3.5 record low minima, 3.33 have survived with one low already tying an earlier record then being tied again in 1981. Feb 21st  (5F) was 1F above the 1896 record (4F) and Feb 22nd (10F) was 2F above the tied 1918 and 1963 record (8F). The minimum of 57F on June 27th was 2F above the 1940 record of 55F and July 29th (61F) was 2F above the 1914 record of 59F. In addition, from three "coldest since" record low minima, there was a count of 2.5. Details follow:

1969 _ Large portions of 1969 had temperatures close to normal values. Both warm and cold spells were brief. Mid to late July was rather cool, and there was a brief cold snap on Oct 23-24 that set records. There was only one tied low maximum for a count of 0.33 which fell to 0.20 eventually with two more ties added. In addition, July 20th (71F) was 2F above the record low maximum of 1869 (69F), and Oct 23rd (43F) was 1F above the 1889 record (43F). The October cold snap resulted in two record low minima which have both survived. There was only one "coldest since" a record low minimum which preceded the two record lows on Oct 22nd.

1970 _ This was a rather bland year weather-wise with long stretches of near average temperatures. January and early April as well as mid-October were somewhat colder than normal and provide most of the few opportunities for records. From 1.5 record low maxima, 1.5 have survived. 21F on Jan 20th was within 2F of the tied record (1875, 1961) but that changed to six degrees in 1994 (15F). June 21st (65F) remains 2F above tied records from 1958, 2003 (63F). There were no record low minima, the closest was 38F on May 7th (within 1 of 37F set in 1891).  Also Feb 26th (9F) was within 2F of the tied records from 1928 and 1990 (7F). There were six "coldest since" record low minima for a count of 4.75. Details follow:

Summary of records set in the decade 1961-70

The decade saw an increase in the numbers of record low maxima and minima over the previous three decades, despite the expected number being somewhat lower. This was largely due to the tallies in 1962, 63 and 68. The output was still not quite up to random expectation however. From 26.83 daily low maximum records (38 expected at random), 21.8 have survived (24.1 random). The latter was higher than any decade since 1911-20. For record low minima, 28.03 records resulted in an eventual count of 23.83. The decade had a total count of 41.7 "coldest since" record low minima, and the total count so far is 201.25, against a total of 312 record low minima. Since some of that count would involve later ties, which would remove years to 1970 from being eligible to set "coldest since" records, the ratio is more realistically 201.25 for about 280 or so. Almost half (163) of record lows (some not yet fully set) still have a "coldest since" in the future as of 1970. The pace of this statistic will continue to run stronger until the 2001-10 decade where it slowed somewhat.

1971 _ Except for a very warm October and a mild December, long portions of this year ran slightly below average but not often into record cold territory. It was quite cold from mid-January to about the 2nd of February. There were two record low maxima with a count of 1.5; both have survived to the end of the data. March 26th (36F) was within 1F of the tied 1872, 1937 and 1947 records (35F). Also Nov 9th (38F) was within 1F of the 1894 record of 37F. The maximum of 16F on Jan 19th was within 2F of the 1904 record but that changed to six degrees in 1994. There was one record low minimum (Nov 9th -- at 28F) which was later broken by 1976 (24F).  The minimum of 7F on Jan 20th was within 2F of the 1946 record but lost ground in 1985 and ended up 7F short by 1994. There were no "coldest since" record low minima in 1971.

1972 _ 1972 was a rather cold year in general much like 1940, but with less of a large collection of record lows and more near misses. This may have been in part due to the larger urban heat island. From 2.5 record low maxima, 1.0 has survived. Jan 16th (15F) was only 1F above the 1920 record low maximum. The interval following Hurricane Agnes (around June 22-26) was persistently cool with highs mostly in the 60s. The maximum on Oct 20th (48F) was one degree above the 1952 record (47F) but that changed to 4 deg when 1974 lowered the record to 44F. From 4.5 record low minima, 1.5 have survived. Aug 11th (57F) was 1F above the 1962 record of 56F. April 9th (29F) was within 2F of the existing record but that increased to 4F in 1977. Oct 18th (37F) was 2F above tied records (35F) from 1929 and 1939 that would later include 1974.  In addition, there were four "coldest since" record low minima, and a count of 2.833; details follow:

1973 _ This was a warmer year and had very few colder than average periods. The first half of January was rather cold but not record-breaking. There were no record low maxima, and the closest approach was 3F on Nov 10th (41F) (record 38F in 1873).  There was one record low minimum (41F May 18th) which has survived (counts 1.0). The low of 58F on July 12th was 1F above the 1926 record of 57F. The minimum of 30F on Nov 11th was 2F above existing record lows, and this increased to six degrees when 2017 reached 24F. In addition there were two "coldest since" record low minima for a count of 1.33; details follow:

Oct 18th (37F) was 2F above tied records (35F) from 1929 and 1939 that would later include 1974.

1974 _ It was a generally balanced year with some warmer periods and some colder, notably June and October. From a count of 2.33 low maxima, 2.0 have survived. Also, Apr 9th (max 40F) was within 1F of the 1885 (later tied 2003) record of 39F, and July 24th (68F) was within 1F of the 1904 record (67F). After records set on 25th and 26th morning low, June 26th (65F) was within 2F of the 1893 record (63F), June 27th (64F) within 3F and June 28th (62F) 2F above the 1938 record (60F). This was a particularly cool late June spell by any standards. There were also 3.17 record low minima of which 2.33 survive. Oct 4th (38F), following a record tied on the 3rd, was within 1F of the 1888 record low (37F). June 27th (57F) was also within 2F of the 1940 record low (55F), and July 25th (59F) was within 2F of the 1953 record (57F). Oct 19th (32F) was within 2F of the 1940 record (34F) and following a record low on the 20th, the 21st (32F) was within 1F of the 1871 record (31F). In addition there were six "coldest since" record low minima for a count of 4.5; details follow:

1975 _ This was generally a rather warm year (in particular May and November) but it had some rather brief cold spells. The first half of April was persistently quite cold (Apr 4-6 37F, 37F, 41F daily maxima) but no records were set. There was just one record low maximum (Aug 7th) which has survived, for counts of 1.0. June 12th (63F) was within 1F of the 1924 record (62F). July 14th (75F) was within 2F of tied record low maxima, and Sep 23rd (59F) was within 2F of the 1963 record of 57F. Also there was just one tied record low minimum (Sep 14th) for counts of 0.5. March 9th (16F) was within 2F of the 1883 record (14F) but that increased to 5F when 1996 dropped to 11F. The minimum of 60F on Aug 7th was 2F higher than the existing record of 58F (1869) and eventually 3F higher after 1994 hit 57F. The last two days of October (33F, 31F) were also 2F higher than existing records from 1925, which has not changed since. Lows from March 27th to April 10th were often within about five degrees of record lows (23F on Mar 27th and 27F Apr 4-5 were notable). In addition there were two "coldest since" record low minima, both tied for a count of 1.0.

1976 _ After a cold January, February to April were generally rather warm but the rest of the year became quite cold again. The autumn and early winter (into Jan 1977) were regarded as exceptionally cold. The count of record low maxima was only 1.0 (Dec 3rd which has survived) but there were several days close to record values. Jan 18th (18F) was within 2F of the 1921 record (later this changed to five in 1977) and Jan 23rd was 15F (record 11F 1871). July 23rd (72F) was within 2F of tied records (70F). Oct 18th (50F) was within 2F of the 1909 record (48F), this changed to five in 2009. 

The count for record low minima was 6.0 and all have survived. This is the largest total in this category since 1963 and would not be equalled after 1976.  May 18th (42F) was within 1F of the 1973 record (41F) and May 23rd (44F) was within 1F of the 1963 record (43F). Nov 8 (30F) was within 1F of the 1886 record later tied in 2019 (29F). Oct 27th (29F) was within 1F of the 1936 record (28F). Jan 23rd (-1F) was within 2F of the 1936 record (-3F), and Apr 27th (38F) was within 2F of the 1932 record (36F). May 20th (45F) was within 2F of tied records (1907, 2002 43F). 

In addition there were eleven "coldest since" record low minima, with a count of 9.58, matching 1967 (which had twelve for the same count) and tied for the highest number of "coldest since" record low minima. Adding that to six actual records and several other days that did not qualify as "coldest since" within 2F gives a total of 22 days with at least near-record cold which, without the urban heat island, would have pushed this year well into the top echelons for cold weather.

1977 _ January remained very cold with several records and near misses. After that, the general trend was warm but occasionally highly variable allowing some brief cold intervals during the spring. May 9th also had the latest trace of snow. From 4.0 record low maxima, the surviving count is a full 4.0. Sep 22nd (59F) was within 2F of the tied 1875 and 1904 records (57F). There were two record low minima which have also survived. (counts 2.0) ... Jan 18th and 29th (which had record low maxima) were within 1F of existing low minimum records as documented in the table of records. May 9th (36F) was also within 1F of the 1947 record as shown, after May 8th (39F) had come within 2F of the 1947 record (37F), which later fell to 36F in 2020. There were also two "coldest since" record low minima, with a count of 2.0. Details follow:

1978 _ This was a rather cold year but was more prone to sustained cooler than average spells than excursions into record low territory. There was only one record set, a low maximum on July 4th (62F) with a count of 1.0. July 14th (74F) was within 1F of the tied record (73F). Other maxima within 2F of a record were 45F on May 5th (1891 had 43F), and 54F on May 16th (1881 had 52F), Aug 5th (70F) compared to record 1903 68F, Sep 8th (65F) with record in 1918 (63F).

There were no record low minima. The closest approach was 1F on July 4th, when 58F was one degree above the 1938 record of 57F (this has since dropped to 55F in 1986, which means that the following 2F "near misses" are now closest to record lows). The 2F near misses include 51F on June 14th (49F in 1875), 59F on July 12th (1926 had 57F), and Oct 8th (41F), and 9th (39F) which were 2F above records until 1988 changed that to 4F for the 8th. Also Oct 18th (37F) was two degrees above the tied record low. In addition, there were seven "coldest since" record lows with a count of 4.583.

1979 _ After a stormy and rather cold January, February turned bitterly cold; it was well below freezing continuously from Feb 9th to 19th although only one record was set with only one near miss included (both on the 18th, the record low was a minimum, the near miss a maximum). Other days were colder but records for those days were lower too. Then the spring was relatively mild, but the summer had unusually cool days and nights from time to time, setting a number of records. There was only one record low maximum (count 1.0), Feb 18th (17F) as noted in the table of records came within 1F of the 1958 record, and also, April 9th (41F) was 2F above the tied records (39F) and Oct 11th (50F) was 2F above the 1951 record of 48F. The last two months of the year were very mild. There were 5.083 record low minima, 4.83 of which have survived (some tied earlier records). Feb 14th and June 25th were within 1F of record lows (see table for details) and so was July 4th although its departure increased later. Aug 12th (57F) was within 2F of the 1889 record of 55F, and Aug 13th (57F) also 2F above the 1930 record of 55F. Oct 10th (37F) was within 2F of the 1888 record low (35F). Only one of these qualified as a "coldest since" either due to later records or smaller 1F departures in other years. 1979 managed one "coldest since" with a 24 degree increase over the lowest ever reading in 1934. The usual range is 1 to 4 deg. Several colder nights in the mid-February cold spell were beaten out by slightly colder readings much earlier in the series, as 1899 held several of those records. Without the larger urban heat island, Feb 1979 would likely be more prominent in the record tables. 

In addition to those, there were four "coldest since" record low minima with a count of 3.33.

* Max of 17F on Feb 18th was within 1F of the record low maximum of 16F from 1958. The previous day had been only 13F but the record for the 17th was 7F in 1896.

 

 

1980 _ This was a rather average year with cool spells in late February, June and around Christmas in December. None of those managed to set a record low maximum and in fact the closest approach was only 5 F which is the largest departure from record territory so far. The days that came that close were Nov 11th (42F - the margin increased when 1987 reached a lower record value of 33F), Nov 18th (38F), and Dec 25th (20F) which later saw the margin increased to 7 F by a lower record set in 1983. Leap Year Day (Feb 29th) had 21F against the 1884 record of only 12F. 

There were two record low minima (count 2.0) which have both survived, June 9th had 47F and Dec 25th -1F. 

In addition, there were six "coldest since" record low minima, for a count of 4.333.

Summary of records set in the decade 1971-1980

The pace of records slackened again, with a total of 14.33 record low maxima of which 12.5 have survived. At random these numbers would be 34 and 24. However, each year had one or two days within 1F of records and several more within 2 or 3, so in fact there was probably about the same amount of cold air present, it was more of a case of urban heat island modification taking the sting out of the cold slightly. And there were some very cold intervals in the decade, most notably late 1976 into January of 1977. The count of record low minima was closer to random expectation, as 25.25 records yielded 20.17 eventual surviving records. There were 33.5 "coldest since" record low minima bringing the total recorded to 234.75. That would be out of 333 records now set. That appears to include 325 fully set, 8 with further ties to come, so the ratio for "coldest since" is actually 234.75 out of 325 possible; 130 coldest since marks (or ties) will still be recorded later than 1980, about a third of them because the record is not yet fully set, and two-thirds because a colder value or tied value lies in the future to eliminate any other contenders. 

Now moving on to the decade of 1981-90, the tables will include all near-misses of 1 or 2 degrees (from 1951 to present it has been just 1 deg with mentions in the annual summaries of those at 2F above record values). Since the tables have all the data, the annual summaries will now be more general and will not contain detailed descriptions of these near misses. The format will be the same, values within 1 or 2 F will be underlined and in brackets. If they come with an actual record value in the other category, the comparison will be in a note below the table. Otherwise the comparison to records will be in italics within the table. 

 

___ Log of records for 1981-1990 ___ 

___ includes all cases within 2F of records ___

 

1981 _ January was a cold month, and February turned very mild. From that point on, much of 1981 was rather close to average or slightly cooler than normal but with very few records. The two records, one of each type and they tied earlier records, so that counts are 0.5 for low maximum and 0.33 for low minimum. 

Note: from now on, almost all records set are surviving to the end of the data, so rather than always mentioning that, we will just confine the commentary to those few cases that do not survive, as we gradually close in on the last records of each type to be set but later are broken. 

There were also no other cases within 2 F deg of records as can be seen from the absence of entries in the table of records. Before that, there were three "coldest since" record lows, none tied, for a count of 3.0. Details follow:

1982 _ This was quite a cold year until near the end when record warmth arrived in December. Mid-January and parts of April as well as the summer were notable for cold records. From 3.5 record low maxima, the count is 3.33 (one was tied a third time, later, in 2003). There was also one maximum within 1F of a record. There were 4.5 record low minima, for a count of 4.33 (Aug 29th was tied a third time, later, in 1986). Four more cold minima were within 2F of record lows as shown in the table. In addition there were six "coldest since" record low minima with a count of 5.33. Details follow:

1983 _ This was quite a warm year and very wet, so not many chances for record low temperatures. May and December had the coldest spells. In fact there would have been no records at all, had there not been a cold outbreak around Christmas setting one of each type of record (counts for both were 1.0). In addition to those, there was one low maximum within one degree on August 13th, and one low minimum within 1F on May 16th and two within 2F on the following two days. In addition, there were five "coldest since" record low minima, for a count of 3.833. Details below:

1984 _ There were longer cold spells again in 1984. Although only two low maximum records were set (counts 2.0), there were also numerous "near misses" ... January, March, and September were all rather cold months. While there were no record low minima, the closest approach was within 1F (see Mar 10 in tables). There were also three "coldest since" record low minima with the count 3.0; details follow:

1985 _ This was a rather variable year for temperatures with brief warm and cold spells, none particularly impressive. There was only one record low maximum on January 21st, (9F -- there has not been a lower maximum since with 10F in Jan 1994) and the only other notable spell of near-record cold daytime readings came in late June (June 26th -28th 68F, 64F, 64F). So the second closest day to a record was within 3F on June 27th. These three days all had minima within 1 or 2 F of record lows and make the table for those. Record low minima amounted to a count of 2.5, and of that 1.33 survived. There were also four "coldest since" record low minima with a count of 3.0. Details follow:

1986 _ This was a rather bland year for temperature trends, and most months were fairly close to normal values. The summer was rather cool. No record low maxima were noted, the closest during the year was within 2F (July 12th) which later became 3F (after 1990), so that April 23rd, June 7th, July 31st and Sep 4th then shared the closest approach of 3F with July 12th, to a daily record low maximum in 1986. There were 3.33 record low minima, of which 2.33 have survived. This marks the last time a record low minimum would be later beaten or tied, so all years after 1986 have either no records or a perfect survival rate. 1999 has the last instance of a broken low maximum record set during the year. There were also numerous lows that were within 1 or 2 F of records, as noted. In addition, there were six "coldest since" record low minima, for a count of 4.67.

1987 _ While this was quite a warm year, there were brief cold spells, notably in late January although not close to setting records, those came in much shorter cold spells of one or two day duration. From 2.83 low maxima during the year, all have survived. There were also two 2F "near misses" as shown. There were no record low minima, the closest approach was 2F on March 11th (16F), Oct 4th (39F), Oct 14th (40F), Nov 11th (30F) and Nov 21st (18F) although Oct 14th changed to 3F after 1988, and Nov 11th changed to 6F when a lower value was recorded in 2017. That leaves March 11th, Oct 4th and Nov 21st as the closest approaches now to any record low minimum in 1987 (margin 2F). In addition, there were three "coldest since" record low minima for a count of 2.5.

1988 _ Generally quite a warm year with a hot summer, there were brief cold spells, notably June 30 to July 2, and October had more sustained cold. From 2.5 record low maxima, 2.33 have survived (one gained another tie in 2004 -- this is the second last low maximum set to have a later tied value, 1992 would also have one, although the last set low maximum to be broken occurs Aug 21, 2007 breaking a record set in 1999). And from 3.5 record low minima, all have survived. This is the highest total for either record lows in the year, or surviving, after 1982 in the record. There were quite a few other lows within 2F of record low minima, as noted. In addition, from seven "coldest since" record low minima, there was a count of 6.0, beaten only twice (2000, 2018) and equalled twice more (1989, 1992) since 1988. Details follow:

1989 _ This year had alternating spells of warm and cold weather balancing out, and December was persistently cold although few records were set. The year had just one record low maximum (Dec 22nd) for a count of 1.0, and one tied record low minimum (Aug 7th) for a count of 0.5. There were a few additional "near misses" in the 1-2F range above record lows.

Summary of records set in the decade 1981-1990

The pace of records picked up slightly from the previous decade, with a total of 16.33 record low maxima of which 16.0 have survived. At random these numbers would be 31 and 24. There was also a healthy crop of "near miss" 1 or 2 F short of being record tying temperatures. These would probably all have qualified in the absence of the large urban heat island effect. The count of record low minima was similar (and lower than the previous decade), with 17.17 records yielding 14.83 eventual surviving records. There were 40.67 "coldest since" record low minima bringing the total recorded to 275.42. That would be out of 348 records now set. That includes 343 fully set, 8 with further ties to come, so the ratio for "coldest since" is actually 275.42 out of 343 possible; almost one quarter of the "coldest since" values are yet to be recorded as of 1990, with only 23 of them due to the record not being yet fully established. The dates for which records in 1990 would later be broken (or tied*) are as follows: Jan 7th, 16th*, 19th, 20th,  Feb 14th and 20th, March 3rd* 9th and 15th, Apr 10th*, May 8th, 9th and 22nd*, June 28th*, July 2nd*, Aug 7th, Sep 20th, Oct 7th* Nov 8th* and Nov 10th, 11th, 12th and 13th, with December fully set including ties. 

 

__ Log of records for 1991-2000 __

 

1991 _ This is the first year in the data set which failed to set a cold record of either type. It would later be joined by 1998, 2006, 2008, 2010, 2011 and 2018. It was also the fifth year (following 1906, 1908, 1941, 1944) not to have surviving records (and would be joined by this same list to make the total eleven). The closest approach for low maxima was 3F on July 29th (72F) and Nov 10th (41F). The maximum of 68F on July 5th would have been a record on July 1st or 7th and was perhaps closer in that sense (although 6F short of the daily record). The closest approach for low minima was 2F on Sep 2nd (53F). That was tied for being coldest since 1892 (52F) became "coldest since" the record low of 51F set in 1886.  Also, 1991 had no "coldest since" record low minima. Of the later years that would join it as being record-free, only 1998 and 2010 were also shut out of that type of near-record. A second close call for "coldest since" was on Sep 28th (45F) which came close to the 43F in 1957 which was coldest after the 1947 record of 41F. 

No tables are required for 1991. The max on Sep 2nd (with the 2F near miss low) was 74 (the record was 62F in 1869).

 

 

1992 _ Much of the year was rather close to average for temperatures, but the summer was chilly and was regarded as "the year without a summer" in some parts of eastern North America (not quite as cold as the historical analogue of 1816 however). This cool tendency was blamed on the late 1991 volcanic eruption of Pinatubo. Cool weather set in during late May and relented its grip rather gradually through the autumn months. The entire collection of records for 1992 comes from the summer, with 2.25 record low maxima (2.20 survive as the tied record was further tied in 1996 -- this is the last instance of a later tied low maximum, 1999 provides the last instance of a later broken low maximum record). There was also one near miss of 1F a day after one of these records. The day following those was also cool at 68F within 3F of the 1909 record for Aug 17th. There were no record low minima in 1992. The closest approach was within 1F on June 22nd, July 23rd and Nov 8th.

In addition, there were eight "coldest since" record low minima, with a count of 6.0. Only 2000 and 2018 would have higher counts after 1992.

1993 _ A generally rather warm year, February and March had cold spells with an inland blizzard around March 12-13 drawing in some record cold air. Mid-October and late December were also rather cold. There were no record low maxima, the closest approach being 2F degrees on July 2nd as shown in the tables. There were two record low minima. (count 2.0). In addition there were  four "coldest since" record low minima for a count of 3.25. Details follow:

1994 _ The year began with a very cold month followed by a gradual return to more normal temperatures through the late winter and spring. The counts were 2.0 for low maxima and 3.0 for low minima. Jan 19-20 supplied two of each and a third record low was added in August. In addition there were five days with "coldest since" record low minima, for a count of 3.83.

1995 _ A generally warm year, 1995 had no record low maxima, and the closest approach was only four degrees (41F on Nov 9th and 24F on Dec 11th). There was one tied record low minimum for a count of only 0.25. The second coldest reading by differentials was 23F on April 5th, three degrees above the 1874 record (1881 took the "coldest since" for that record at 21F. There were two "coldest since" record low minima, with the count 2.0.

1996 _ The year was quite variable in temperature with some large swings during each season. The count of record low maxima was 1.2 (March 9th and a tied mark on July 23rd), but there were quite a few more near misses. The count for low minima was 1.0 (also March 9th) but the second closest call was 3F above a record on several occasions. In addition there were three "coldest since" record low minima for a count of 1.83. A coldest since (8F) shared with 1955 was removed on Feb 4, 2023 by a colder reading in 2023 (3F) after the record low (0F) set in 1886 and 1918.

1997 __ A rather warm year in general, 1997 had no record low maxima. The closest approach was 1F on July 24th (68F). A second near miss by 2F occurred on Aug 20th (70F). There was one tied record low minimum for a count of 0.33. There were six "coldest since" record low minima for a count of 3.83.

1998 _ It was a very warm year on average although the summer was closer to normal and sometimes rather chilly. This year joined 1991 as the only two so far with no record low maxima or minima, and also had no "coldest since" record lows. The closest approach to a record low maximum was on July 8th when a high of 69F was 2F above the 1894 record. This changed to 3F when 2005 was colder at 66F. That was equalled on June 12th (65F, 1924 record 62F) and Aug 19th (73F, record 70F from 1881 and 1946). March 11th and 12th were 4F and 5F above daily record low maxima. For the minima, the closest approach was 3F on Aug 20th (58F, record was 55F in 1949). No table is required for 1998; the minimum on July 8th was 64F (56F the record also in 1894, 2005 recorded 62F). There were several quite cool nights in early June in the range of 5 to 7 deg above previous record lows. Every minimum June 2nd to 10th was in the mid-50s. (F)

(table would read July 8 __ (69) _ (64) ____ not records in 1998 (1894 _67F, later 2005 _66F; 1894 _56F))

 

1999 _  This was another quite warm year. It has the last instance of a low maximum record that would later be broken (64F, Aug 21, 2007 replaced with 59F). This large shift means that now, three other days share the smallest departures from record low maxima (3F): July 14th (76F, record 73F), Sep 22nd (58F) and Oct 5th (53F). 

October 7th gave 1999 a count of 0.5 for a tied minimum (39F). Otherwise the closest approach to a record low minimum was within 4F (July 11th, 61F). There were no "coldest since" record low minima in 1999, the first time that two consecutive years failed to produce one (as of end of data) since 1907-09 were all shut out (1907 mainly because it was so cold that it set numerous records rather than going coldest since). There have not been two more consecutive years without coldest since (as seen from 2022). 2010 and 2012 are the only other years yet to come that will not record any. A minimum of 9F on Jan 2nd was within 2F of the coldest since value (7F in 1922) for the daily record of 2F (1918).

2000 _ Some parts of the year were quite cool relative to normal values, in particular the summer and autumn. This allowed the production of 3.5 record low maxima, a value not repeated in any later year (from now on, no new records set have yet been broken, so that survival rates are always 100% for those years that have any records). In addition there were a number of near-misses as shown in the table of records. For record low minima, the year produced none but it did have five days within 1F which were Apr 27th, Sep 5th, Sep 29th, Oct 9th and 10th, for which further details appear in the table. In addition, nine "coldest since" record low minima for a count of 6.833 make 2000 the most productive year since the record holders 1967 and 1976, later to be equalled by 2018 (with eight days, same count).

Summary of records set in the decade 1991-2000

The pace of records begins to fade with two years out of these ten failing to produce any records at all. From 9.95 record low maxima, 8.9 have survived. One (in 1999) was broken in 2007, and another tied record received one more later tie (out of five), which is the full loss of 1.05 records (and the last of these, the next two decades will retain all their records). At random these numbers would be 29 and 24. There was, however, a significant number (13) "near miss" 1 or 2 F short of being record tying temperatures. Most would probably have qualified in the absence of the large urban heat island effect. They bring the production up to about random expectation so that we could hypothesize that most of the absence of record low maxima in the decade was caused by the urban heat island. However, 1994, 1996 and 2000 were more prolific than most other years. The count of record low minima was even weaker at 7.08 (all have survived, 1986 being the last instance of a non-surviving share of a record low minimum). Add to those 17 more near miss situations (within 1 or 2 F) and the total begins to look more similar to random expectation; however, 2000 provided almost half of those extra cases. There were 28.08 "coldest since" record low minima bringing the total recorded to 303.5. That would be out of 355 records now set. That includes 352 fully set, five with further ties to come, so the ratio for "coldest since" is actually 303.5 out of 352 possible; almost one sixth of the "coldest since" values are yet to be recorded as of 2000, with only 14/60 of them due to the record not being yet fully established. The dates for which records in 2000 would later be broken (or tied*) are as follows: Jan 7th, 16th*,  Feb 14th and 20th, March 3rd* May 8th, 9th and 22nd*,  July 2nd*, Nov 8th* and Nov 10th, 11th, 12th and 13th, with December fully set including ties. 

 

__ Log of records for 2001-2010 __

 

 

2001 _ This was quite a warm year generally speaking, and had only a few brief cool spells. There were no record low maxima, the closest approach being 2F with 37F on March 26th. The second closest was 3F on Sep 30th (55F). There was one tied record low minimum, 56F on July 2nd, and a near miss of 2F on October 8th (39F). In addition, four "coldest since" record low minima gave a count of 2.5 for the year. Details follow:

2002 _ Although a rather warm year, 2002 had a few cold spells, most notably mid-May. That produced the closest approach to a low maximum record on May 18th (2F), a similar close approach to a record low minimum also on the 18th, and one tied record low minimum (43F on May 20th, tied 1907), with another near miss of 2F on the 21st for the minimum. Mid-June had some cool days (63F) within 3-4 F of records, and July 26th (71F) was also within 2F of the low maximum just tied the previous year. Aug 29th (65F) was also within 2F of the record low maximum. Oct 29 to Nov 2 was also rather chilly. After the tied record low minimum and adjacent 2F close approaches, the next closest approach was 3F on May 19th, which was one of four "coldest since" record low minima in 2002, for a count of 2.833.

2003 _ The winter turned quite cold with numerous near-record lows mid-February to mid-March as shown. It stayed cold into April with two more tied record low maxima added (37F Apr 8th, 39F Apr 9th), and later June 21st tied a record set in 1958 (63F), giving a count for the year of 1.17. In that same interval a sixth share of the March 3rd tied record low minimum completed that record (count 0.167). May 22-23 saw a return to cold with two near records. Sep 2 was also nearly record cold. Other portions of the year were closer to long term averages but it was seldom warmer than normal by any large amount. In addition, there were six "coldest since" record low minima, but the count was only 2.417.

2004 _  January was cold and set a few records or near misses. Much of the rest of the year was warmer than average and cold days were infrequent. The counts for record low maxima (0.33) and minima (0.5) are joined by just a few near misses. There were also three "coldest since" record low minima (count also 3.0). Details follow:

2005 _ January was quite cold but did not quite get into record range. Much of the year was very warm, with brief cold spells. One record low maximum was set on July 8th (66F), for a count of 1.0, and low minima came within 2F on Dec 14th. There were three "coldest since" record low minima with a count of 2.0.

2006 _ This was often quite a warm year and it became the third year (after 1991 and 1998) without record low temperatures; however, there were two "coldest since" a record low with a count of 1.5. Both followed record lows set last in 1979. The closest approaches to record low maxima were 4F on June 7th (65F) and Sep 2nd (66F).

2007 _ This was frequently a rather cool year with a four-day remarkable cool interval from Aug 19th to 22nd during which a monthly record low maximum (59F) was set. The count for record low maxima was 2.0. There were quite a few near misses as well. A four-day cold snap March 6-9 was notably cold for the christmas pudding. The closest approach to a record low minimum was 1F on July 2nd (57F) and Aug 11th (57F). In addition there were six "coldest since" record low minima with a count of 4.5. Details follow:

2008 _ Although not a remarkably warm year, 2008 became the fourth in the series to produce no record low maxima or minima (following 1991, 1998, and 2006). The closest approach to a record low maximum was 3F on Oct 29th (46F). The closest approach to record low minima was also 3F but was shared by two days, Aug 11th (59F) and Aug 20th (58F). From three "coldest since" record low minima, the count was 2.0.

2009 _ It was occasionally rather cold in the winter and spring, and cool through the summer, with a more significant cold spell in mid-October. There were three days with record low maxima (count 1.67 due to two being third ties); two were in the interval of Oct 15th-18th which also had two near misses of 1F. There were no record low minima, the closest approach was 1F on March 3rd (12F). From four "coldest since" record low minima, the count is 3.5.

2010 _ Temperatures were often well above normal values. Parts of late January and mid-May, mid-December were cold but there were no record low maxima or minima for the fifth time (1991, 1998, 2006, 2008). The closest approach for low maxima was 1F on May 12th (48F) with Dec 14th (23F) within 2F. The closest approach to a record low minimum was 4F degrees, also on May 12th, as well as May 13th. 2010 was also the third year (1991, 1998) with both no record lows and no "coldest since" record low minima.

Summary of records set in the decade 2001-2010

The pace of records stayed low, comparable to the previous decade, in this generally warm decade. There were 6.83 record low maxima, all have survived. At random these numbers would be 27 and 24. There was, however, a significant number (19) "near miss" 1 or 2 F short of being record tying temperatures. Most would probably have qualified in the absence of the large urban heat island effect. They once again bring the production up to about random expectation so that we could continue to hypothesize that most of the absence of record low maxima in the decade was caused by the urban heat island. Several years were however quite weak producers of cold weather even with that advantage added. The count of record low minima was much weaker at 1.67 (all have survived) and there were none after 2004 (an absence which would last until January, 2014). However, if we add to those 15 more near miss situations (within 1 or 2 F) the total begins to look somewhat closer to random expectation; it could be stated that a 3F advantage is needed to restore the count of near-record low minima to the long-term average. There were 24.25 "coldest since" record low minima bringing the total recorded to 327.75. That would be out of 355.5 records now set. That includes 355 fully set, one with a tie to come (Nov 8), so the ratio for "coldest since" is actually 327.75 out of 355 possible; almost one tenth of the "coldest since" values are yet to be recorded as of 2000, with 11 of 36 of them due to the record not being yet fully established. The dates for which records in 2010 would later be broken (or tied*) are as follows: Jan 7th, Feb 14th and 20th, May 8th, 9th,  Nov 8th* and Nov 10th, 11th, 12th and 13th, with December fully set including ties. 

 

 

2011 _ This was often a very warm year. For the second consecutive year, there were no record low maxima or minima. This was the sixth such year (1991, 1998, 2006, 2008, 2010 also had no records). Unlike some, 2011 did have one "coldest since" a daily record low. The closest approach to any record low maximum was 2F on Oct 29th (45F), the occasion of the "Hallowe'en snowstorm" that set a one-day snowfall record for October at NYC. The closest approach to any record low minimum was also 2F on the same date (33F) and the following (Oct 30th, also 33F). The one "coldest since" was the 28th of October, details below:

2012 _ This year continued mostly very warm (March in particular) but there were relatively colder days in the summer and autumn at times. There was only one record maximum, a fourth tie for Nov 7th (41F) so the count is 0.25. Nov 6th and 8th were also quite cold as shown. There were no record low minima and the closest approach was 2F on June 26th (58F) and again on Nov 7th (31F).

2013 _ This was a generally rather warm year with only brief cold spells. There were two days with record low maxima, July 25th (68F), and Nov 24th (30F tied 1880), the count was 1.5. There was also one near miss by 2F on June 7th. If that had been a record it would have brought the count to 2.5 which is the random expectation at this late stage (2.4 is where it finishes by 2022). There were no record low minima and the closest approach was 2F on May 14th (42F). That was one of three "coldest since" record low minima and the count for those was 2.5.

2014 _ This year brought the first of the two consecutive "polar vortex" years to the region, and temperatures stayed relatively low Jan to Mar, then mostly moderately warm at times for the rest of the year. Despite the first quarter chill, there were no record low maxima, the closest approach being 1F on Mar 26th (36F). Also there was one record low minimum on Jan 7th (4F), the first since Jan 16th, 2004, almost ten years elapsed without one. It would be necessary to go as far back as Mar 1996 to find the last set full record low, anything that occurred 1997 to 2004 was a tie of an already-set record low minimum. The second longest interval with no record low minimum set was 2.5 years from Sep 27, 1957 to Mar 12, 1960 (there are now longer intervals without surviving record low minima). There were in addition six "coldest since" record low minima for a count of 4.75 in 2014.

2015 _ The second polar vortex winter was even colder especially in February but there were mostly "near miss" type results with one new record low minimum (2F on Feb 20th). The rest of the year took considerable time to warm up relatively, but ended with a record warm December. There was one record low maximum (58F on June 1st, tied 1945) for a count of 0.5, with 55F on the 2nd as noted not a record, and also the count of 1.0 for the record low minimum. In addition, there were four "coldest since" record low minima for a count of 2.5. Details follow:

2016 _ The mild winter continued to mid-January after which there was both a record snowfall (Jan 23rd) and a record low minimum (Feb 14th -1F). After that, much of 2016 was rather warm with very infrequent below normal temperatures. The closest approach of any low maximum to a record was also on Feb 14th (15F) within 3F deg of the 1916 record. In addition, there were two "coldest since" record low minima, count 1.33.

2017 _ This was a sometimes quite cold year with one day reaching record low maximum status (count 0.25) but four more "near misses" of 1 or 2 F, and several more within 3 or 4 F (not shown). There was a brief cold snap overnight Nov 10-11, setting only low minimum records (count 2.0). Again, there were several other minima within 3 to 5 degrees but none within 1-2F of records. In addition, there were two "coldest since" record lows, count 2.0; details follow:

2018 _ Although sometimes rather cold, especially in January and November, 2018 became the seventh and last (so far) year not to set any record low maxima or minima. The closest approach to a low maximum record was 1F on Jan 6th and 7th (13F, 18F) and on Sep 9th (62F). There were two other days within 2F and one within 3F of record low maxima. The closest approach to a record low minimum was 1F on Jan 7th (5F) and again on Nov 23rd (15F). In addition, there were eight "coldest since" record low minima, for a count of 6.833, the highest in recent years. Some were fairly impressive such as close approaches to the Nov 1880 record cold.

2019 _ This was a variable year for temperatures and had its share of cold spells. These set 1.5 daily low maxima, and 2.5 daily low minima. Cold spells in late January and mid-November were most impressive. In addition there were four "coldest since" record low minima, for a count of 4.0.

 2020 _ While large portions of this year were quite warm, early May was unusually cold, in particular the night of May 8-9 which created two daily record low minima. There were no daily low maxima, the closest approach was within 3F on Nov 2 (44F) and also Nov 18 (36F). Between those two cold days came a week of record warmth with highs into the mid-70s. In addition there were four "coldest since" record low minima for a count of 3.5. However, one of these is weak, due to 2019 being the record and 2021 the only other year that could set this mark (which it did for Nov 8 and 13).

Summary of records set in the decade 2011-2020

The pace of records stayed very low, even lower than previous decades, in this generally warm decade. There were 4.0 record low maxima, all have survived. At random these numbers would be 25 and 24. There was, however, a significant number (15) "near miss" 1 or 2 F short of being record tying temperatures. Most would probably have qualified in the absence of the large urban heat island effect. They do not quite bring the production up to about random expectation but we could continue to hypothesize that much of the absence of record low maxima in the decade was caused by the urban heat island. A differential of 3F would restore the count to the expected number. The count of record low minima picked up to reach 9.5 which was the highest since the 1981-1990 decade. Here again if we add near misses the total gets fairly close to random expectation. Given that there were no records until 2014, it would seem that the climate has perhaps naturally cooled somewhat in this past eight years although we are of course nowhere near being back to the "glory days" of the 1960s or earlier decades for production of record cold. 

There were 28.42 "coldest since" record low minima bringing the total recorded to 356.17; that would be out of 364 records set before 2020. A count of 9.83 "coldest since" that existed at the end of 2020 have been created (for the two 2020 records), replaced (six more) or tied (four more) by 2021 to June 4, 2023. There has not been a record low minimum set since May 9, 2020.  A summary for the decade 2021-30 will not be possible until after 2030, but it can be noted that the decade is off to approximately the same start as recent decades on a pro-rated basis. 

 

__ Log of records for 2021-2030 __

 

2021 _ In this rather warm year, one brief cold spell at the end of May managed to set 1.5 low maxima (May 29, 30 both 51F). These are impressively low daytime readings as illustrated by the fact that the June record is 52F (and May 31 57F). Otherwise there were very few cold daytime readings in 2021. July 3rd (66F) came within 2F of the record. There were no daily record low minima, the closest approach during the year was 3F on May 31st (49F) and July 31st (60F). From five (edit four now) "coldest since" record low minima, the count is 3.5. The two related to 2020 record lows were "automatic" and were challenged by 2022 and 2023 ... turns out that May 8 was removed by 45 in 2022, the 46F on May 9 survived for another challenge in 2023 which it survived.

A very cold Dec 24th came within 1F of breaking the low (6F in 1983) and 2F the high (13F in 1872). There have been five "coldest since" record low minima, with the count 4.5..

As is the custom of this thread, updated files are made available on the Net-weather equivalent thread (they are too large to download here). 

https://www.netweather.tv/forum/topic/93113-toronto-180-a-north-american-data-base-of-182-years-now-includes-nyc-1869-2022/page/4/#comments

The only changes made to them since the last time they were available would be the addition of daily data and various other monthly data for March, April and May 2022. 

[Roger Smith]

Another season is in the books, these internet thread files have been updated, and so have the supporting excel files. A link to those can be found in the previous post. 

In general the summer of 2022 was quite warm at both NYC and Toronto; it was the third warmest August on record at NYC. One daily record high maximum was set at Toronto (35.8 C on June 22) and the highest reading at NYC was 97F on August 9th but that was not a daily record.

It was quite a dry summer for NYC and surrounding region, not as dry for Toronto although slightly below the long-term normals.

Files both here in the thread, and in the supporting excel documents, are updated (to end of 2022, I did not yet edit the Jan 4 tied record high at NYC into the thread, mention is made of it in the excel file). 

As the supporting excel files are too large to store on Am-Wx, you need to navigate over to Net-wx to find them here:

It's interesting that no readings above 65 occurred between 7th and 14th inclusive. Perhaps this year will void that outcome. The record high for the 7th is particularly low-hanging and could go soon, you would think.I have also listed any other readings not (or no longer) record highs in the 65+ category. Also listed are any "warmest since" more ancient records (two from 1874 and 1890 as well as LYD 1880 have survived).

In the opening post of this thread, I mentioned the resource of Alexis Caswell's Providence RI weather journal which runs from December 1831 to May 1860. This substantially overlaps Toronto's record starting March 1840 but is entirely before the Central Park weather station began operation. Obviously the events at Providence would resemble weather in the New York area more than Toronto, in fact by comparing the journal with Toronto and the newly available NOAA weather map reconstructions (1836 to 1850 were added to what had existed before), one can see that in general (a) the era had very frequent coastal lows that often impacted Providence and sometimes missed Toronto altogether, and (b) the maps themselves are probably quite deficient because obvious well-defined lows passing Providence barely show up, one suspects that ship reports in the Atlantic were used as a source for these maps but Caswell's journal appears to have been unknown to the map creators. They do seem to have known of the Toronto weather records. Other east coast weather records must have come into existence because by the 1840s the maps begin to look more detailed and also begin to match Caswell (who has very detailed barometric and wind records as well as temperature and precipitation). 

This section will list the daily extremes noted by Caswell during the period Dec 1831 to May 1860. His reporting is about 98% complete in that interval, with most of the infrequent gaps lasting a few days around late summer probably indicating a habitual time away for a local vacation or family visit (Caswell was a professor at Brown University). His temperatures are taken from sunrise, mid-day and 10 p.m., and he rarely (but on some extreme occasions) mentions more extreme values from other times of observation. So these daily records should probably be taken as "there or thereabouts" with the idea that many of them could be a bit less extreme than what a log of daily extremes would show. The precip records that I quote here are either one-day or two-day ending on the date cited. There is no easy way of breaking down his precipitation numbers by days and there are frequent overnight rainfalls (and snowfalls) summarized as totals. On rare occasions a two-day event will be reported by Caswell as two daily amounts. There, I have shown the two-day totals by asterisk since those would be comparable to many of the other record values due to the majority being two-day totals (a few events may be three-day totals, in all likelihood these would include one day at either end with quite small values, if I can make an educated guess by pressure or wind or cloud data which those are in the case of end-of-three-day values, I exclude the date from inclusion in the reporting here. The snowfall records are sometimes based on a 10:1 conversion of all-snow precip totals but are more often based on his direct measurements which tended to be expressed as a range over two inches, as in "ten to twelve inches." Caswell melted down snowfalls and sometimes has different ratios, for example on Feb 9, 1832, 0.40 precipitation was noted as 7 inches of snow. Many events had mixed rain and snow but he consistently noted the snow portions. From his comments we can see that he endeavoured to measure "level" snow rather than drifts. 

The few times that Caswell records a temperature to a half degree have all been expressed as the more extreme of the two possible roundings, for example, -4 and a half was -5, not -4, 18 and a half would have been 18 for a low, rather than 19 (my assumption was if the temperature had been observed at 18.5, it was very likely 18.4 or lower at some point in time), but only the negative cases actually came into play, no values above zero were ever expressed with a half degree precision. This was only done a few times early in the series, mostly in the cold spell Jan 3-5 1835.

Jan NOTES: (in order of dates rather than years) ____________ _____ ____ Feb NOTES: 

* also 1.00 _1844,56* .. 3rd 1856 was an ice storm.

*4th-5th 1852 1.20" (0.60" est 4th) edged out similar two-part .. __  ___ *1st 1843 _ 50F est from notes, early morning. 1.08" rain not a record

.. 1836 0.75" recorded as 0.50" 4th + 0.25" 5th. 

*5th-6th 1856 heavy snowstorm, precip and snowfall records are

placed so as to allow other heavy fall to remain in the records but

it appears that roughly equal amounts fell on both days in the 1856

storm which left severe snow drifts, estimated 18-20" level snow.

*5th 1838 also 58F (not a record) _________________________ ________ ____ *5th 1848 _2.95" total 4th-5th, may have included 0.40" from wet snow

*6th 1845 snow with some sleet, rain by 7th, the amount for __________ event on 1st, not clear from notes, but either way would have replaced

 6th-7th was 1.00" not a record, the amount on 6th may have _________ ... 1843 _ 2.20" liquid _ (first part of storm snow, amount not given) ...

been similar to, or a bit more than, 1842 as shown (0.65"). _____________ ... the 1848 storm had roughly similar snow by 5th to known amount of

* 7th also 1855 had 54 F. ________________________________________________ ... 6.5" (1832) so these are listed as co-record holders, together with 1854

*14th also 1.40" (13th-14th) 1856, mostly rain, 4.0" snow. ______________ ... where 0.3" liquid gave "six or seven inches, much drifted" by a.m. 6th.

*16th-17th 1844 _ Two day mostly rain, started wet snow ... ___________ ...

... portion on 16th likely similar to record shown, two-day ... ___________

 total beat second place value of 1.15" from 1841 (17th). _______________ *7-8 1853 2.40" rain, 2.25" is recorded for 7th and 0.15" for 8th.

*18-19 _ The very heavy 3.60" rainfall is based on Caswell's total of

.. 4.00" for 18-19, where he says 4" of snow fell on 19th, which would

.. imply 3.60" rain on 18th. There was 2.50" liquid in the heavy snow

storm of 18th-19th 1857 and also 1.00" rain on 19th in 1838. _________ * 7-8 1836 1.75" precip, snow to rain, no snow depth given, est at least 7"  

* 21st may have had similar precip from first half of 1850 event on ____ * 8th 1854 1.50" snow changed to rain, 5.0" snow an estimate (it melted

 21st-22nd, that event mostly rain but started with some snow. _______  ...  by end of the event a.m. 9th. Also 1.25" rain 8th 1857, ice jam flooding

*22nd-23rd 1840 1.75" about 10" snow all fell on 22nd, 1.25" of ______ *9th 1855 12.5" snow 8-9, 7.0" also fell in 1832 on 9th.

 entire event recorded for 22nd (probably 0.50" rain of this on _______ *9 1840 1.55" rain 7th-9th, probably most fell on 9th (about .15" 7th, 8th)

 23rd, under rules used the full amount counts for 23rd. _______________... also on 9th, 1850 had 1.45" rain

*24th also -8 1837. ____________________________________________________ *15-16 0.87" 1838 a mixed fall of snow, hail and freezing rain. 3-4" snow likely

* 25th-26th 1835 two daily measurements, 0.62"+0.25" ______________ *16th 1860 1.00" precip, 9.0" snow (includes some on 15th)

so that 0.87" 1835 applies to 26th, the 0.62" portion replaced________ * 17 1835 0.80" rain, comments say "sleet" may have been an ice storm. 

0.60" from 1832 which was a one-day event but two-day event_______ * 19-20 1832 0.67 + 1.03 = 1.70" 1858 had 1.25" 19-20. 

24th-25th 1836 recorded 2.50" ... that was likely about evenly ________ *21-22 1.75" may include small amounts from days before 21st, storm was

split between the two days which explains the bracketed 1.25" ________  ... a two part snowstorm with total estimated 12.0" first day estimated 8.0"

value for the 24th. Snow during that event was reported ______________ *23 also 0.87" 1838 and 0.75" 1837

as 5.0" and came in several portions of a mixed event.

 Note also 1.50" 24th-25th 1845 (rain). 

* 26th also 54F in 1851, 53F in 1835, 1838 and 1849

* 27th 1838 1.04" .. there was also 0.33" on 26th but that 

was not continuous with the 27th fall of rain and hail. Even

so by the rules being used, the 1.04" can be taken as 1.37"

This was in any case pushed out by 2.50" on 27th 1848.

* 28th 1855 may have exceeded these values but is part of

a total of 1.00" 28-29 which is difficult to break down.  A total

of 1.70" liquid (mostly rain, some snow) fell 26th-29th 1855.

============================================================

due to fewer two-day rainfall totals used by Caswell, max precip values are daily except as noted.

The files in the thread have been updated to show Jan-Feb 2023 and winter 2022-23 values where needed.

It was a very mild winter at NYC with only 2.2" snow to date; Toronto has had its sixth mildest winter but snowfall picked up at times and the totals are closer to long term averages. 

The excel files have also been updated. Due to size limits, I cannot post those here, but they are on the parallel Net-weather thread. To navigate to the excel files, follow this link:

The spring season is in the books, relatively warm at both locations, in particular mid-April with several daily records falling at both Toronto and NYC. May was quite dry, at Toronto there were two dry spells, 8th-18th, and 21st-June 1st. Both locations hit 91F on June 2nd, not quite a record value for either, and then fell off to near 10 C by morning of 4th -- at NYC that proved to be within one degree of a record low set in 1926. The current northerly flow pattern is bringing in a lot of forest fire smoke from widespread blazes in central Quebec and air quality has been poor at times.

No new work has been done in the thread files or on the attached excel files, but in both cases, all required data updates and file maintenance have been done. A project for the next quarter of the year will be to provide seasonal data for NYC which is not yet shown in the thread. (this data does exist for Toronto) ... files are stored so that they will open at site navigation info panels. Those will guide you to the various data blocks available -- these are large and complex files with a lot of information. 

Thiis is a link to the excel files posted on Net-weather (cannot post them here, too large) ...

New York City (NYC) Seasonal average temperatures 1869 to 2023

Winter includes the preceding year's December. 1868-69 had no data for December. A provisional value of 1.5 C is used for Dec 1868 based on comparisons with locations that did have data. The Jan-Feb average alone (1.56) is similar.
