yes and immediate coast means the beach, not where I live which is 2 miles north of the beach.

we're a lot hotter than 82 here, I hit 87 here about 10 minutes ago

there are so many issues with it that go far beyond temperature, like higher rates of asthma and cancer (and light pollution causes cancer too.) not to mention that high rates of processed food consumption lead to obesity, diabetes, heart disease, etc. So urban farming has multiple benefits.

Ironic that you mentioned Sandy, Walt, the last time I remember such extreme heat so early was in June 2012, and we experienced Sandy a few months later.

the parks department sucks, I read that they are replacing playground grass fields with astroturf, which causes more heat and more injuries.... cheap goons (they dont want to pay for upkeep, watering, mowing, etc).

Incidentally, there's a major push in NYC and other large urban cities like Chicago, to greenify the city. Because UHI has major health implications too. The pledge is to make the city at least 30% green by 2030 and remove a lot of the concrete pollution where people live. We're also seeing it with the push for rooftop gardens, urban farming, community gardens, etc. So maybe greening the city will help control UHI and its health implications on people (while also cleaning the air, as more greenery means less air pollution and lower asthma rates too.)

Yes no doubt there are major foliage issues now and I think that manifests itself most in wet patterns like we were in until recently. It's much less of an issue when we're in a dry pattern.

well, the park maybe (which is what thousands of people do), but not in the concrete jungle of course.

Right thats my point and yet Central Park was also cooler by a significant margin in 1966 (and apparently also in 1973 when the high temperature at JFK was 100 and only 94 at Central Park.) I think the real conclusion to draw is that the park isn't representative of Manhattan as a whole and when you measure temperatures in a park you'd expect them to be lower than they would be in the concrete jungle or at an airport. Sure Central Park has foliage issues, but you'd expect their temperatures to be cooler even without those issues, as happened in 1966 and 1973.

wild, I didn't know about that one Don and that was before the overfoliage era at Central Park. It's even more than the 5 degree difference on July 4, 2010 (101 at JFK, 96 at NYC). Do you know offhand what the high at Central Park was on May 29, 1969 when JFK had their one and only 99 in May, Don?

omg JFK already had 8 90 degree days at this point in 2010 and NYC only had 4? LOL

June 27, 1966, is that the earliest 100 degree temperature recorded at NYC? So next week we have the potential to have our earliest 100 degree temperature at both NYC and JFK?

incidentally that 1 99 degree day in 1969 is the earliest on record, with a high of 99 on May 29, 1969, I think it's pretty crazy that the record high for both May and June is 99, it shows that June has the potential to be hotter than 99 and we're overdue to break that June monthly record at JFK (which was tied 4 times).

Yes, JFK exceeded NYC by 5 degrees on that day and yet no one seems to remember it (except me)-- that day really stood out to me.

The hilarious thing about JFK is they hit 99 4 times in June but not 100 (not yet)..... the other hilarious thing is they also hit 99 once in May, on May 29, 1969.... which shows that not only is 100 possible in June at JFK, it's also inevitable. Let's see if this is the June that will do it. Having the same record high for May AND June is not something I would expect to last..... Regarding NYC, what I find so ironic is that the record highs for next Monday and Tuesday (both 96) are from 1888....... This is the earliest extreme heat we have seen since 2012 when we were in the upper 90s around this time around the entire area (including JFK).

we have the opportunity to have the earliest 100 degree temperature at both NYC and JFK next week.... not sure what NYC's record is but I think it's from 1966 Tony? Was it earlier than the extreme heat we will have next week?

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.)
