Thanks for this, benchmarks always intrigue me and I remember a few of the ones you listed. Do you have a list of benchmarks for JFK too? That 95 in early October is one that comes to mind for me. And of course the earliest ever 100 that occurred last week has also become a benchmark now. Another one is the earliest ever 99+ degree temperature on May 29, 1969 that really stands out to me as well as the earliest 90 degree reading from April 11, 1977. It's interesting that the JFK period of record began in 1948 and they immediately recorded their latest 100 degree temperature in the same summer (and back to back 100+, while NYC had three in a row during that same span of time.)

Had that here on June 24, 106.0 and 102.6 the day after. Beat my July 22, 2011 mark at the same location which was 105.6

I wonder if this is record max heat for Paris?

This was all your doing, Santa Claus!! Christmas in June (in more ways than one too!!)

anything near as historic as the 40C London experienced a few years ago?

Changed it to a cooler blue theme, it's actually from April 2002 during the historic heatwave, you wouldn't think the skies would be this blue but they were, a function of it being April, despite the intense heat.

It's interesting how we do not have late season intense heat anymore (at least to my knowledge)-- we did have 95 in October here a few years ago (at JFK). But our latest 98 in recent memory was in September 2010 and our latest 99 was on September 11, 1983 wasn't it? Our latest 100 goes all the way back to September 7, 1881 (actually 101.) It was NYC's first 100 ever recorded and also its latest.

Wait, do you mean my sig, I guess I should change the picture lol. Thanks, I appreciate you too.

I consider you a friend, Rob so thank you :-) I'll try to use multiquote more often, it does work sometimes, but it limits me to two quotes per post from what I can tell. I'm using the DuckDuckGo browser.

No they weren't Only the last 10 days of June are part of summer. If you're familiar with 1980 there was historic heat for all of July and all of August and the first three weeks of September that covered the entire CONUS except for the extreme Pac NW and Maine. A thousand people died in Saint Louis alone from the intense heat (1995 Chicago was similar to 1980 St. Louis.) NYC's couplet of July and August is still the hottest 62 day period on record and August 1980 is the hottest August on record and the only one with a mean temperature of 80.0 or above. But 1983 was an even hotter summer (going by the metrics I use.)

it's been completely sunny and hot here for an hour now, going to turn on my a/c soon.

I know about the other historic summers but what late hot streak did we have in 1973? Thats my birth year lol

None on the 11th or 12th or in the entire 24-30 period which is very WEIRD. Too bad the 31st broke the streak otherwise it would have been a clean sweep for every day in July after the 23rd lol.

Also isn't there a whole week at the end of July when NYC has never hit 100 (I think it's July 24-30).

It depends on how extreme it is. If it goes below zero then it's interesting (same as 100+). There does need to be activity around the bookends though (just like with winter.) January 1994 was much more fun than January 1985. Both went below zero, but January 1994 had much more activity.

The heat was just getting started in the final week of the month and lasted into September A nice dress rehearsal for 1983

sucks no 1980 style continuous heat, but at least the peaks are higher this year (for us anyway).

The sun is here and I see large patches of blue skies now Don :-)

That was one of our last really great summers, the heat in 1999 almost matched 1953 in terms of longevity, truly a summer to treasure. I was disappointed that JFK only reached 100+ once (102 on the 5th), which is why I rank 2010 higher and completely unmatched (1966 had as many 100+ days but the heat didn't continue into August and September like it did in 2010.) However in terms of longevity of heatwaves 1999 is only exceeded by 1953. I don't believe it's a coincidence that we have an 11 year return period for the peak of extreme heat (1944, 1955, 1966, 1977, 1988, 1999, 2010.) Of course if you want to feel cool, Chris, all you need to do is jump in the water

what causes all this variability in recent heatwaves (since 2013) that keeps them short, Walt? Compared to much longer heatwaves for example in 1944, 1953, and more recently 1980, 1993, 1999, 2002, etc that lasted much longer. 1980 for example, we basically had a heat ridge sitting over our area for 3 months (June 20th through September 20th).

it's brightening up now, Tony :-)

Indeed- that's why I cherished getting over 40C/104F on the 24th lol. The other thing I like is how C and F are the same at -40 !!!!

Is this considered some kind of artwork Don? It does look like origami.

There is no perceptible difference between 98, 99 and 100 degrees. So if it's going to be 98-99 it might as well be 100. 105+ etc isn't necessary.

That can be easily disputed in terms of the numbers of people who died in those summers AND in terms of extreme heat (duration of heatwaves and number of 100 degree temperatures.) Those are the only metrics I care about. Since 2011 this is the first summer that has matched the intensity of those older summers (even though the length of heatwaves has now become much shorter.) 3-4 day heatwaves really do not stand up to heatwaves of 7 days or longer (which is why they are called super heatwaves.) You clearly were not alive for summers like 1983 or 1993 or you would never make such a statement.
