If you live on the Atlantic side of FL, there is always an ocean breeze to regulate the air. Up north, it gets more hot, more oppressive and more stagnant than in FL.
As to the humidity, we actually have higher humidity here in Hotlanta than we ever had in FL. I would put those white crystals (the chemical name escapes me) in the closets to keep the humidity away from clothing, etc. As long as things are vented properly and you run the A/C, humidity is usually not a problem.
