95 with a dew point of 78 is MUCH worse (and much more boring) than 101 degrees and a dew point of 45 or even 55.

Looking at pictures from the 1930s-1950s era, I think that was a much drier era with much less foliage in our parks, which explains the more extreme heat of that era.

Yes Newark being inland has seen a rise in 90 degree days but not 95 or 100 degree days. So the wetter climate has been tempering their extreme heat too. But 1950 wasn't one of those hotter years like 1944, 1948, 1949, 1953, 1955. But I agree about mins, they are definitely elevated compared to the previous era.

So there hasn’t been any long term decline in 100° days in NJ and Central Queens away from the cooling influence off the bay at LGA during the 2020s. Oh yes there's been a notable decline in 100 degree heat, nothing to match 1993's 9 days of 100+ or 1949's 8 days of 100+ at EWR..... cmon Chris, CC has more of an influence on mins than it does on maxes and thats because of our new wetter climate. It's got way more to do with more rainfall and more of a subtropical rainforest climate we have now vs what we had in the 1930s-50s and the 1990s.

EWR: 97 (1993) now this is what a real hot summer is like....something we haven't seen in a long time.

as usual in our new climate, this isn't the 1950s.

101 degrees with a dew point of 45 would be far more comfortable and represent a lower power load.

I predicted this shit days ago.

Yes as usual in our new climate, without the 100+ highs.

It's a tropical rain forest here, I have so much overgrowth going on here that I'm spraying defoliant to kill everything. I have no time to cut this forest I have going on in my front yard, so spraying it is.

mean temps have no real connection to extreme highs, during the summer mean temps are mostly driven by elevated mins, we have the same thing going on here. I can prove this, we have seen an overgrowth of foliage with the wetter climate we have been in. This isn't merely about them neglecting trimming the foliage, it's about this kind of overgrowth not being in existence in the 1930s-1950s when we had many more extremely hot days and a much drier climate. The pictures you posted prove it-- during that earlier era we did not have as much foliage as we have now in our parks and that's because it was much drier back then, which is also why the extreme heat was much hotter Sure, the places you listed just now are hotter, but it's because they exist in an artificial concrete climate without much in the way of trees. Coast or no coast, there is no way we would EVER match the extreme heat of the 1930s-1950s except for brief intervals like the 1990s and the early 2010s, unless we switch back to a much drier climate.

This isn't the same Chuck that we had in 2006-07 *warmest winter ever* LOL

mean temps have no real connection to extreme highs, during the summer mean temps are mostly driven by elevated mins, we have the same thing going on here.

good point about the 60s-80s but the 30s-50s period might be part of a cycle and when it repeats it will be even hotter....also much drier back then. The atmosphere is taking on the properties of water in terms of specific heat with how humid and wet it's become lol

but that doesn't explain that huge spike during the 30s, 40s and 50s and then we dipped during the 60s, 70s and 80s when the equipment was still properly sited.

It also left out the huge spike during the 1930s-1950s period

Yes this is why our summer heat hasn't been as extreme as it was during the 1930s-1950s and during the 1990s either.

I know but the number of 100 degree days from the 1930s through the 1950s and the number of years with 100 degree days is far in excess of anything we had before or since so that is probably cyclical, I wonder when we will see a return to that kind of heat again?

They should have done a tally by decade, so I'll try to do that myself. Number of 100+ days per decade / number of years with 100+ days per decade 1880s : 1 / 1 1890s : 1 / 1 1900s : 2 / 1 1910s : 3 / 3 1920s : 2 / 2 1930s : 8 / 5 1940s : 8 / 3 1950s : 12 / 5 1960s : 4 / 1 1970s : 3 / 1 1980s : 2 / 1 1990s : 8 / 4 2000s : 1 / 1 2010s : 5 / 3 Doing this tally I'm a little shocked how many 100 degree days had between the 1930s and the 1950s and despite the enormous exception of 1966 which had 4 of them (the only 4 of that entire decade!) a big downturn in 100+ degree days began during the 1960s which only spiked again in the 1990s before resuming the downward trend. The early 2010s were an exception of course. There is obviously something cyclical going on here. No other way to explain what happened during the 1930s-1950s period. And how quiet it was both before and after that. And look at how both the 1930s and the 1950s had half of their years (5) hitting 100+ -- that has never been matched either!

eh to be fair Chris, 50% more is somewhat more than slight (9 to 6) 1993 had slightly more than 1949 did though (9 to 8)

and 1949 somehow had 8 in EWR and 5 99+ days at NYC, wow

Here are all of NYC 100+ days. I find it somewhat ironic that the first recorded 100 degree day (in 1881) was also the latest it's ever happened, 101 on September 7th. https://www.weather.gov/media/okx/Climate/CentralPark/100DegreeDays.pdf 100 Degree Day Information at Central Park (1869 to Present) Last Updated: 1/22/25 100 Degree Facts * Highest Ever Recorded: 106 on July 9, 1936 Most Days by Month: June 3 + July 42 + August 13 + September 2 = Total 60 days Most in one year: 4 (1966 and 1953) Most consecutive 100 degree days: 3 July 8-10, 1993 & August 26-28, 1948 Last time had 100 degree day in September: the 2nd in 1953 (102) Last time had 100 degree day in August: the 9th in 2001 (103) Last time had 100 degree day in July: the 18th in 2012 (100) Last time had 100 degree day in June: the 27th in 1966 (101) 100 degree days before 1900: Sept 7, 1881 (101) and July 31, 1898 (100) All 100 Degree Days Year Date / Temperature (°F) 2012 Jul 18/ 100 2011 Jul 22/ 104 Jul 23/ 100 2010 Jul 6/ 103 Jul 7/ 100 2001 Aug 9/ 103 1999 July 5/ 101 July 6th / 101 1995 July 15/ 102 1993 July 8/ 100 July 9/ 101 July 10/ 102 1991 July 20/ 100 July 21/ 102 1980 July 20/ 101 July 21/ 102 1977 July 18/ 100 July 19/ 102 July 21/ 104 1966 June 27/ 101 July 2/ 100 July 3/ 103 July 13/ 101 1957 July 21/ 100 July 22/ 101 1955 July 22/ 100 Aug 2/ 100 Aug 5/ 100 1954 July 14/ 100 July 31/ 100 1953 July 17/ 100 July 18/ 101 Aug 31/ 100 Sep/ 102 1952 June 26/ 100 1949 July 4/ 102 Aug 9/ 100 1948 Aug 26/ 103 Aug 27/ 101 Aug 28/ 100 1944 Aug 4/ 100 Aug 5/ 101 Aug 11/ 102 1937 July 9/ 100 July 10/ 100 1936 July 9/ 106 July 10/ 102 1934 June 29/ 101 1933 July 31/ 102 Aug/ 100 1930 July 21/ 102 1926 July 21/ 100 July 22/ 100 1918 Aug 7/ 104 1917 July 31/ 100 1911 July 3/ 100 1901 July 1/ 100 July 2/ 100 1898 July 3/ 100 1881 Sept 7/ 101

during the early 90s when we hadn't had any big snow seasons for over a decade, I used to go to the library and read NYT on microfiche and seasons of yore like 1947-48 and 1960-61 and 1966-67 and 1977-78

For NYC too, check out this old NYT article https://www.nytimes.com/1993/07/11/nyregion/heat-wave-records-rewritten-as-east-bakes-and-midwest-soaks.html

Were the total number of 100+ days (9) far in excess though? A few of them must have been in June and August in 1993.
