Welcome to meteorological fall!
It’s basically how the weather community measures seasons…if you were wondering. Astronomical fall doesn’t occur until the autumnal equinox on September 22 at 10:29 pm EDT.
Here are some numbers from “summer” (May 1 – September 31) at Jacksonville International Airport.
Average high temp: 90.8ºF (-0.2ºF)
Average low temp: 71.5ºF (-0.3ºF)
Average temperature: 81.1ºF (-0.3ºF)
The total precipitation number is kind of funny to me. It’s almost like the international airport is on an island when it comes to rain. I know… it’s Florida… you can have heavy rain at one place and 2 miles down the road…nothing.
Total precipitation: 10.26″ (-9.54″) Driest on record, according to the Southeast Regional Climate Center. (Period of record at JAX goes back to 1948. “Normal” is taken from 1981-2010.)
The good news is… JAX has seen 36.09″ of rain for the year (+0.73″).
Random facts for “summer.”
-Highest temperature was 99ºF on August 22.
-Lowest temperature was 62ºF on June 4.
-Greatest 24-hour precip. total was 1.72″ June 6-7. (again, comical…we’ve have some spots in northeast FL get 3+ inches of rain in one day with some of the storms.)
As for “fall”…. we go from average temperatures of 72ºF/89ºF on September 1….to 47ºF/70ºF on November 30.
Sunrise goes from 7:03 a.m. to 7:05 a.m.
Sunset goes from 7:49 p.m. to 5:26 p.m. !
“Fall” features the climatological peak of the Atlantic hurricane season: September 10.
It’s also National Preparedness Month. Here’s a FEMA Video.
Now I’m going to find a pumpkin…
