Average temperature defines warmth but not hot. Here are the rankings I found: By the way, AI agrees with me and it seems that number of hot days correlates with average temperatures too. Here is AI's answer: What is the hottest summer on record in New York City? AI Overview The hottest summer on record in New York City was in 2010, with an average temperature of 77.8 degrees. This summer was hotter than the previous record of 77.3 degrees set in 1966, NYC has had a warming trend for years but there hasn’t been as many super hot days. In fact the 12 year gap between 100 degrees is the longest since 1881 - 1898 (and the 2nd longest in recorded history). Last year, despite being the warmest in NYC history by a significant margin (.6 warmer than any other year) the high was only 93. Here is the hottest summers page for NYC (AI agrees with me AI Overview New York City has experienced some extremely hot summers, with the hottest ones often occurring in the late 20th and early 21st centuries. The hottest summers since 1869, based on data from the National Weather Service, have all been since 1960, with 2010 being the hottest on record according to TypePad. The summer of 1966 had the hottest average monthly high temperature, while July 1999 had the hottest average daily temperature. Here's a breakdown of New York City's hottest summers: 2010: This summer is often cited as the hottest, with an average high temperature of 86 degrees Fahrenheit between June and August according to Yahoo. 1966: While 2010 had the hottest overall summer, 1966 holds the record for the hottest average monthly high temperature according to TypePad. 1999: This summer had the hottest average daily temperature in July. 1993: This year had the most 90-degree days during the summer months (35 days). Other Notable Summers: 1983 and 1991 also rank among the hottest summers in NYC's history. I also use Typepad for both summer and winter records, this site is a veritable bonanza of information. https://thestarryeye.typepad.com/weather/2012/07/revisiting-new-york-citys-hottest-summers-.html New York's five hottest summers (since 1869) have all occurred since 1960: 2010, 1966, 1993, 1983 and 1999. The fact that just one of the years is from this century may surprise some since these years were so warm worldwide. The summer of 1966, New York's second hottest on record, has the honor of having the hottest average monthly high temperature. Although July 1999 was the hottest month on record based on mean daily temperature (average of the day's high and low), the average high in July 1966 was hotter than July 1999 by 0.1 degree, 90.3° vs 90.2°. However, July 1999's average low was 3.5 degrees warmer (72.6° vs 69.1°) and that's what easily put it on top. Although 1991 and 1993 had the most 90-degree days for a calendar year, each with 39, 1993 had the most during the summertime period. It had 35, followed by 1966 with 34 and 2010 with 32. 1991 had 31, ranking fourth. https://www.weather.gov/okx/heatwaves This is the NWS Heatwave page for NYC National Weather Service New York, NY NYC Heatwaves Page Weather.gov > New York, NY > National Weather Service New York, NY NYC Heatwaves Page Current Hazards Current Conditions Radar Forecasts Rivers and Lakes Climate and Past Weather Local Programs Longest NYC Heatwaves Longest Heat Waves - 90 degrees + in a row (through March 10) Days Dates Temperatures 91,91,91,94,98,99,98,100,97,102,94,90 92,97,97,93,96,97,93,92,90,98,90 98,100,101,102,97,94,94,91,90,90 90,94,92,97,95,98,94,96,93,90 92,96,98,95,92,93,94,94,94 93,92,96,98,97,100, 102,92,104 91,93,91,91,91,94,99,101,95 93,94,91,94,92,91,93,93,91 96, 95, 95, 96, 97, 90, 92, 91 91, 92, 91, 94, 93, 94, 96, 95 98, 95, 98, 94, 95, 94, 96, 93 97, 102, 97, 96, 95, 95, 96, 95 91,91,93,95,95,100,100,94 93, 93, 91, 94, 96, 90,96 93, 93, 95, 94, 96, 99, 97 90, 93, 96, 99, 96, 100, 102 94, 93, 94, 98, 96, 93, 97 94, 95, 96, 93, 94, 94, 93 98, 100, 90, 95, 100, 97, 93 92, 97, 100, 101, 91, 90, 90

I remember we had a Con Edison controversy (what else is new lol) when this happened a few years ago and the power went out in specific neighborhoods and not in other neighborhoods. I think that was in July 2019 when we had back to back 99 degree days with a heat index of 117 (at JFK). On a weekend too.

Thats my favorite kind of heat.... the specific definition of hot that the NWS uses is number of 90 degree days and they even rank summers based on that on their page. Top heatwaves are ranked by number of days over 90 consecutively and hot summers are ranked by number of 90 degree days overall. No argument about the lethal quality of high dew points, thats why I have argued that removing water vapor from the atmosphere is much more important than removing CO2. We can remove water vapor from the atmosphere and make pure drinking water out of it.

There's a possibility our airports might have to shut down from extreme heat.....

Long live 1966 and 1993 and 2010 and 2011 some of our hottest summers on record, notice that EWR and JFK hottest days and hottest summers match up well, Walt!!

1928 - A farmer near Greensburg, KS, looked up into the heart of a tornado. He described its walls as rotating clouds lit with constant flashes of lightning and a strong gassy odor with a screaming, hissing sound . (The Weather Channel) I wonder what caused that *strong gassy odor* inside the tornado..... fertilizer combusting?

Number of 90 degree days are what defines *hot* You can have a very warm summer with elevated minimums and with a high average departure without it being a hot summer.

Records: Highs: EWR: 98 (2012) NYC: 98 (1923) LGA: 98 (2012) JFK: 94 (2012) Lows: EWR: 52 (1956) NYC: 49 (1914) LGA: 55 (1959) JFK: 55 (2005) Historical: 1682 - A major tornado ripped through southwestern Connecticut, passing through Stratford, Milford, and New Haven, and then into Long Island Sound. (Sandra and TI Richard Sanders - 1987) Tony wow, so maybe 2012 will be an analog to this summer? 2010-2013 had summers similar to what we might be about to embark on.... 1682 tornado, I wonder if that would have been recorded as an F3? There certainly were more strong tornados in this region during that era, you listed 2 for yesterday also.

Yes 2013 had our last 7+ day heatwave (at NYC). The 2010-2013 period was more like what we had from 1991-2002 and prior to that from 1944-1955.

some of our heavy hitting summers in that list like 1949 and 1966 and 2010 !! lol it's funny to see a record at Central Park from 1888 not having to do with the big blizzard.

thats absolutely amazing and what I'm hoping for. It's going to be very hot, let's make some history!

In my experience the compressional heating will be down here near Sunrise Highway. The contrast of the water temperatures didn't make much difference in April 2002 or 2010 either. Long Beach might be in the 80s while Valley Stream is 100+ We made it past 90 easily on a SW wind over a week ago. A NW wind will be at least 10 degrees hotter here. No sea breeze before 4 pm and by then we will already have exceeded 100. On days like this our temperatures rise as quickly as Newark's does (notice how JFK's hottest days and years match up well with EWR's) and we usually exceed 100 by noon or 1 pm at the latest.

Isn't this what happened in the 1944-1955 when we had those 7-12 day heatwaves with 95+ and 100+ temperatures? I know you're all about climate change, but that was a cyclic pattern we had from 1944-1955 and which repeated itself from 1991-2002, so maybe that cycle is returning?

I love those martian dust storm colors

People are worried about high heat causing power outages, I think it's pretty obvious the most power outages are caused by severe weather like we had yesterday. Thousands of homes without power because of those storms and lots of damage, large trees down!

If this was caused by a super el nino can we find a way to modify the ocean currents to reverse it or just prevent el ninos like that from ever happening again to make things worse?

Instead of volcanoes which are extremely dangerous and can kill thousands of people, why dont we work on climate modification to fix what we caused?

lots of trees down and some very large ones too, I thought my windows were going to blow in that afternoon

88 here too, temperatures dropped after 12 noon..... now 90 at 2:30 pm with lots of sunshine!!

Thanks, when was the last time it happened-- maybe July 2010 or July 2011?

do you know if it was a direct strike or if it hit a tree first or the ground first?

wow it rained here for one hour 7-8 and pretty hard for about 30 minutes very windy and very dark

Nice and toasty, it was 88 here at 12 noon.

Yes, even a Cat 1 might be too much, do you remember when we had that high end tropical storm that moved to our west a few years ago? My house was shaking with 80 mph wind gusts.
