It's not a problem only in Florida, try to bow hunt elk in the Rocky Mtns. some time, the wind is never consistant for very long.
The best you can do is try to play the wind, but also do your best to prevent excessive sweating by moving slower to your stand and take some of your favorite scent killer spray to the stand with you and spray down once you have reached your stand and cooled down. Spray all of your equipment, stand, everything.
Good Luck.
