I've been to Florida many times...usually in the winter.However,I've been there once in April and once in October.The October visit was almost intolerable...95 degrees and 95% humidity.
I've also experienced 100 degrees on the Arabian Peninsula (Dubai) and found it not nearly as bad as Florida in October.
Try May through September when it is so hot and especially humid because it is the rainy season, that I have to shower twice a day working outside sometimes and change clothes several times. I just get soaked. Sopping wet through and through. Socks, shoes, pants, shirt, undershorts, everything is soaking wet.
It is an oppressive heat where your face feels like it's going to burst. Like a steam bath that gets hotter and hotter the longer you're in it until you can't stand it anymore and have to burst out into the fresh air and a cold shower to survive.
I like hot. Much better than cold. But this heat is villainous. Treacherous. Almost obscene.
