To be fair, summers should always be judged by number of 90/95/100 degree days.

Don't Meditteranean hurricanes occur when it gets this warm Chris?

1993: Flash flooding rolled across southeast South Dakota and into northwest Iowa. A phenomenal 6 to 7 inches of rain fell in Dickinson and Emmett Counties during a 3 to 4 hour period. The Des Moines River rose several feet in just a few hours. Ocheyedan received 3 inches in just 45 minutes and Allendorf picked up 2.80 inches in 30 minutes. Many locations in northwest Iowa reported winds in excess of 60 mph, with some locations clocking speeds of 70 to 80 mph. Several tornadoes were also spawned during the evening in Emmett County in the Ringsted area, 3.50 inch hail fell and baseball size hail covered the ground just north of Estherville. Millions of dollars in damage was caused from the thunderstorms across the area. 1993: No river traffic was moving on the 585 miles of the Mississippi River from St. Paul, MN to Cairo, IL and on 535 miles of the Missouri River from Sioux City, IA to the point it joined the Mighty Mississippi. More than 5, 000 loaded barges were stranded. For the first time in history, major floods came down both rivers at the same time. (Ref. Wilson Wx. History) 1993 was historic on so many levels, our endless summers and the endless flooding near St Louis.....many records on both ends that have never been equaled or exceeded.

The hottest 24 hour period at Central Park has to be July 5-6, 1999 with a high of 101 and a low of 83 (and a high of 101 again the following day.) It's absolutely amazing that 1908 had lows of 84 in both July and August, that must have been one hot summer! July 1995 is right up there too with a high of 102 and a low of 84 and extremely high dew points. September 11, 1983 is notable for having a high of 99 and a low of 78, mid summer weather in mid September. April 2002 is notable for lows in the mid to upper 70s and highs in the mid to upper 90s.

If you go by 24 hour periods of highest average temperature would you say that the July 5-6, 1999 period was the hottest 24 hour period on record at JFK, Don? The high was 102 on July 5th and the low the following morning was 82! June 24-25 comes in second place with a high of 102 and a low of 81 the following morning. It ranks higher in terms of duration because June 25 also had a high of 102 while July 6th fell below July 5th highs (only at JFK, at NYC it was the same as the previous day, at 101.) I'm surprised that July 2011 isn't on this list, as JFK had back to back highs of 103 and 102 in that stretch so the lows must have been elevated also. It's also interesting how highs made it into the 90s from a start in the low 60s in April 2002. And I knew May 1991 was extremely hot with 7 90 degree days but didn't know that we had our earliest 70 degree low in that month! That period at the end of August 1948 was also notable with a high of 101 and a low of 78.

wild, 98 on September 10, 1983 and then 96 on September 11, 1983 after two 100 degree readings in July and August, 1983 and 2010 were our only truly great summers (great from beginning to end.)

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
