I completed my PPL and 50 hours of hour building in Florida and can tell you that the weather conditions are no more favourable stateside than mainland Europe.
I done the same Yorky, only I completed the Helicopter PPL. Tbh I wouldn't go back near Florida to fly. The weather caught me out a few times plus the endless amount of our feathered friends in the sky. Every time I went up it was like an obstacle course. If I went back to America to fly I would go further inland or hit the West Coast to try it out.
