Thanks Tony, that's exactly how I remember it too.

The high of 101 on July 4th at JFK, was 4 degrees higher than Central Park if I remember correctly and also higher than LGA. I think EWR was the only other official ASOS in the area to reach 100 on that day.

2010 has the station record for all these locations, Tony?

also for 100+ days I think the record is 4 from 1953 and 1966 at NYC? and for 100+ days the record is 3 from 1966 and 2010 at JFK?

Thanks Don..... in 2010 JFK also had 3 days of 100+ July 4th, July 6th and July 7th, if I remember correctly? (so three days out of four?) The 3 days of 100+ in 1966 at JFK were all consecutive?

I read (I think from AI.... so not sure if this is accurate) that by 2080 we will see a much steeper rise in extreme heat and our number of 90, 95 and 100 will all double from where they are now, do you think that could be accurate, Don?

Nice, why does 1948 have a yellow square around it, is that because 1948 is the start of the dataset for JFK, Tony? I know all 3 of those in 2010 were 100+ All 3 in 1966 were also 100+ The 2 listed in 1993 were also 100+ The 2 listed in 1948 were also 100+ The 1 from 2013 was 100.

for it to be prolonged we need to match the 7+ day super heatwaves we had in the past (sometimes multiple in the same summer). Our longest heatwaves are still from 1944, 1953, 1993, 1999, 2002, etc. It will probably happen eventually, but it hasn't yet. Even this upcoming heatwave is the typical 4 day one.

Can you include JFK in this list too, Tony? I know they had 31 90 degree days in 2010 , 10 95 degree days and 3 100 degree days (one more than NYC.)

Yes, I wonder how many official NWS ASOS locations measure their temperatures in a park?

Tony do you have a list for JFK and NYC in terms of 99 and higher? I know 1949 takes the number one spot for 99+ temperatures at NYC with 5, not sure what is number 1 for JFK, but I know they have the same number of 99 degree temperatures (19) that they have of 100+ temperatures (also 19), which I find absolutely amazing.

I loved 1993 I consider that my hottest summer on record in terms of how hot it felt (2010 was much drier), so this matches my experience. I see 1988 up there and it matches 1949 for second place, I came back from a long overseas trip in August that summer and my house was like an oven when I got back. Good to see 2022 in a tie with 1953 and 1999, two other historically hot summers with very long heatwaves.

Yes 2022 was extremely hot no doubt, but we still have not been able to match 1949 or 1993 for extreme heat so it makes me wonder if there is a natural limit to how hot it can get. Obviously if we keep warming on this trajectory whatever those thresholds are they will eventually be passed.

a few days ago NYC exceeded LGA by 1 degree. Fortunately some of us have excellent memories and remember these things.... also what was going on in July 1966 when the temperature at NYC was only 103 and LGA was 107 and JFK was 104 and EWR was 105? Were those foliage issues too? Temperatures in a park will be cooler, with or without foliage issues, folks....

The really interesting thing about inland areas, let's take Newark as an example, is that they have never matched the number of 100 degree days they had in 1949 (8) or 1993 (9). I wonder if there is a ceiling to how much CC can affect inland areas for summer maxima too Don? Factoring in the additional amount of moisture added to the atmosphere because of CC, there might well be.....

Monsoon climates have a secondary maxima in September, Chris. I know, because in my travels around the world, I've experienced these climates. They have a primary maxima in May and June and a secondary maxima in September and October.

and yet in early July, JFK exceeded Central Park when it hit 104.

we haven't matched the heat of the 2010-2013 period or how widespread it was, look at this amazing 2012 heat we had in June LGA: 98 (2012)JFK: 97 (2012)

That's correct, what the people with reading comprehension issues missed is that I specifically referred to extreme summer high temperatures. And there is a reason why that hasn't happened and that also has to do with climate change, namely that adding more moisture into the atmosphere makes it much more difficult to pass previous record highs in the summer. It's basic physics folks.

FWIW it isn't just the coastal areas that are seeing less extreme temperatures, Newark itself hasn't come close to matching the number of 100 degree days that happened in 1949 and 1993 either. The data shows it.

of course we all believe in climate change, we just do not agree how it manifests itself in all areas. Many of us have looked at the data and we see it affects minimum temperatures MUCH more than it affects maximum temperatures during the summer. If you read the text of what I posted, I referred specifically to summer maximums. In the winter the situation is different, it affects maximums just as much as minimums. This is a nuanced discussion and you can't apply the same effects to different seasons or even to different times of the diurnal cycle. That's what most people miss. and the phrase *global warming* has been retired in favor of climate change, because climate change much more accurately describes what's going on.

Incidentally it would have been 90 here with more sunshine.

I thought you like cooler temps

Tony, what's the earliest JFK has hit 100? I know they've hit 100 multiple times in my life on or just after July 4th. July 4, 2010 101 degrees (hotter than either NYC or LGA) July 5, 1999 102 degrees

note how JFK is hotter than either LGA or NYC on an offshore wind.
