That makes more sense.

My suburb gets 28 days (based on 57 years of records)

NOAA shows Lexington to have 23 days as the average number of times hitting 90+.
In 2012 they had 42.
Most for Lexington was 68 days 90F+ in 1944.

NYC's average number of 90 degree days. I would think that LGA would have more 90 degree days than Central Park? The means and max temps are slightly higher?
That's when you notice the water gradient playing a role. More humidity but tames the temps.
Obviously the flow has more to do with temps then the water and it seems easier for a Ridge to build over you then here which would mean warmer temps there than here.

LGA mean is same as Central park. 17.

Miami Florida 30yr Average number of days 90°F+ is 87.
Most of 121 in 2009
Least was 44 in 1984

Funny to see the "least" number of days for Miami is double the amount of NYC's average.
That's Horrible just thinking about that. lol

Also depends on how far above 90 it is. For example, my city averages about 200 days a year above 90 but usually it is only 92 or 93. Days above 95 are incredibly rare. Doesn't happen every year. So it isn't that bad. Like I said earlier, it's always hot but never too hot.

LGA?


According to this, it's 17 days above 89.9F for the period of record, with 48 being the max number of days at LGA in 2010

NCDC also has LGA's 1981-2010 normals at 16.9 days

Here are the monthly reports form the April-Sep period in 2010. Steamy summer for sure...

Interestingly, Central Park's record number of 90 degree days is way behind LGA at 37 in 2010, wonder why the big discrepancy?

In 2012 Midway had 48 days at or above 90, and O'Hare had 46. In 1988, Midway had 48 and O'Hare had 47.


As for 85.9F the mean number is 37 with the most being 67 also in 2010. I'm not sure how you came up with 41?

This is tough question to answer because of the Fahrenheit/Celsius thing. Environment Canada used to list number of days above 90 back in the 1980s when we were on Fahrenheit, but now it's 30C(86F) and 35C(95F).

Kamloops has 32.8 days above 30C and 7.2 days above 35C. Therefore, I would estimate there to be 25 days per year at or above 32/90.

I live in NC and it gets to a million degrees here in the summer. I can't fathom how anybody decided to settle here. I could just imagine that buggy ride. I would be the one screaming bloody murder because it's too hot! It's fun since we have a pool in our subdivision. Otherwise, I would have sponteously combusted already. ;-)
