one of the great myths of all time "you can catch a cold from the change in weather"  Nope you need to be exposed to a virus.

it depends on how it's communicated.  If a change in the weather exposes a weak immune system then it's possible.  Generally speaking, viral infections are more contagious in cold and dry weather because virus particles stay in the air longer.  Conversely bacterial infections are more common in the summer because bacteria love warm and humid weather.

I'm confused I thought he loved cold weather lol.

I like short heatwaves with breaks in between of weather like we have now.

I think going forward the only realistic way this happens is if we get these June heatwaves. With the warmer planet and warmer water it would be hard to get into the 60s in July following a major heatwave, but in June when the water isn't as warm yet it's more realistic, CAA not so much but still more likely in June rather than July. 

I think it has happened in August before, though I don't remember what year-- maybe 1993?

Today is just the 5th day on record that Central Park has seen the temperature fall into the 60s following a day with an 80° or above minimum temperature. There were 72 days with 80° or above lows.

 

2002 wow and that was a really hot summer (hot and dry, which we need to get extremes like this.)

Yeah, all the lawns in Long Beach during July 1999 turned brown. 1999 to 2002 was the last time that the NYC reservoirs ran low. These days flooding has become more of a concern than drought. 

a characteristic of summers like 1999 was that we would have weeks without any frontal passages (this also happened in 1993) and then the drought would be broken with a tropical deluge in September after the peak of the heat had already passed. I remember 1991 was also like this, but the tropical system that broke the drought was Hurricane Bob in late August.  We did have a couple more 90 degree days after that in September though.

Seems as if a lot of people here are enjoying it. After 3 days of extreme heat, this is a refreshing change. I wouldn't want this cloudy cool weather to last for too long, but I'll take 2 days of this after that insane heat. It was too hot to go running outside the last 3 days, so I'll enjoy running out there today and tomorrow. 

Yes a few days of this is pretty nice.  4 days of this and 3 days of the other is an interesting roller coaster lol.

we need a 2002 type pattern to have this happen more often.

all three summer months were below average and july had a low in the 50s

Looks like a mostly pleasant summer outside of a 5-day heatwave in late August, which, to be honest, was probably urban heat island related anyways. Isn't that the usual explanation for heat extremes these days? Certainly, seems suspect that the Central Park readings went from among the highest in the CWA to among the lowest in the recent heat wave.

In 1948, the first 24 days of August, prior to the heat wave, were pleasantly cool. The mean temperature for that stretch being 72.5F, which has been surpassed on the cool side only three times since (1962, 1992, and 2000).  The average high temperature, a chilly 79.2F. High temperatures that have only been seen once for that period since (2000). A true summer of yesteryear.

unfortunately it also means less extremely hot days so our climate is becoming compressed to higher mins and less high temperatures of 95/100 or more.  1949 must have had lower low temperatures to balance out the 8 high temperatures of 100+ at EWR and 5 high temperatures of 99+ at NYC.

 

1949 had record August cold despite the 100° days. So in those days, the heat tended to get balanced out with cold. Plus the following 1950 summer was the 6th coldest on record.

Rained last night, dropped to 76 last night then the temp rose to a high of 81 around 4am which is unheard of. Having temps rise above 80 at night only to drop into the 60s in the 70s during the day in late June is pretty impressive

Very interesting. If you look at the U.S. national temperature records, 1950 was the coldest year overall since 1929, culminating in all-time record cold and snowfall in late November. But 1951 was even colder, reaching temperatures that have been surpassed on the cool side only twice since (1978 & 1979). The winter of 1950-1951 remains the snowiest on record at Pittsburgh. I wonder if the massive Chinchaga firestorm in British Columbia played a role in that impressive national cool spell. You should look at "Black Sunday" in September. Temperatures in the 40s and pitch blackness. We really hadn't seen anything like that again until 2023. Fortunately, it's looking like the Canadian smoke situation has tampered down for the time being, so, hopefully, that won't have a big impact on temperatures the rest of this summer.

Another interesting thing, seeing 1936 on that list. That really jives with my research. They claim 1936 is the hottest summer on record, tied with 2021. But it looks like it was overall quite cool for most of the eastern United States. Except for that record heat wave that lasted about a week in July, I'd even say downright chilly. Overnight low temperatures were impressively cold in much of rural Pennsylvania that summer. Without that brief stretch, it looks like it would have been one of the coldest on record in many places. Quite odd that it is tied with 2021 for hottest on record.

If you look into the numbers, the heat was driven by ridiculously high 12F anomalies (on the plus side) in states like North Dakota and South Dakota where nobody lived in 1936 (and still few reside to this day). I wonder how much the loss of crops and at least temporary desertification played a role in amplifying those numbers. They adjust for "urbanization" but don't make any adjustment for the massive amounts of irrigation and the unnatural density of corn and soybeans across the Plains and Midwest. Without the UHI adjustments, I bet 2021 would take the crown, and some other recent summers would surpass 1936 as well. Also, not saying they should make any crop-based adjustments, but it does strike me as odd how certain human-caused environmental changes are factored in, but others are not.

[Roger Smith]

2025 reduced 1888 in the roster of all-time records, from 2.0 to 0.5 daily max, and from 1.5 to 0.5 high daily min (it still has a tie with 2015 for a December high min, and it retains a tie with 2025 for June 23rd max. 

2025 also reduced 1909 from 4.0 to 2.0 daily records for high minimum values, and reduced 1952 to a one-third share of monthly high min. 

The counts for June 2025 are 1.5 and 3.0 daily records (max, min) and two-thirds share of the monthly record high min.

I think 1936 sort of gets a pass because people see all the all-time records (including state records) that extend all the way to the East Coast, but it really wasn't that hot of a summer for most areas in the overall means.

it's fascinating how extreme heat was balanced out with extreme cold.

the same must have happened after 1953 and 1955.

1944 was much hotter than 1936. Likewise 1966 was the peak of the heat prior to 1993.

There is a theory out there that the 5 summers between 1944 and 1955 that had extreme heatwaves were hot because of nuclear testing.

I hate those corn and soybean crops, all those subsidies have an extremely negative effect upon the environment and on our health.

November 1950 triple phaser

1953 was our most extreme summer on record never saw anything like it so it rubber banded back to extreme heat again in 1953 and 1955. Then back to cold again for the last few years of the 50s and the early 60s before the historic heat of 1966 and then cold again after that.

No urban heat island in 1948..... that was one of the most historic periods of heat on record with NYC peaking at 103 and three straight days of 100+ and JFK had back to back days of 100+ which has only happened a couple of times and that was the only time it happened after August 20.

1953 was much more extreme though and it has records for longest heatwave and peak September heat that still stand to this day.

1954 had at least a brief shot of extreme heat as well, but maybe it didn't reach all the way to the coast. I know Ohio and western Pennsylvania had 99-100+ temperatures widespread on the 14th. Typically, the coastal Plain is several degrees (3-6F) warmer during hot spells, but maybe the air mass petered out. I believe those heat waves were enhanced by drought in the middle of the country as well, similar but not as extreme as the 1930s drought.
