How is it that 70° F be both:
- a sign that Florida’s long summer has begun
- a barometer that a winter day is here?
You’re 100 percent correct!
Winter to a south Floridian is “any day” that doesn’t heat up above 70° F.
Summer also uses that same magic number,
Only in its case as a “night-time” low.
Which is where we are at now.
(Only the rainy season hasn’t started — so much for rules of thumb!)
Those summer deprived citizens still haven’t felt the mercury rise above 70° F for a single day in May, and just recently had a string of night-time lows in the 30s.
Of course that’s T-Shirt weather for them.
