Been there in August and September and last year September was actually hotter than the two previous Augusts so it all depends on the weather. It was freezing here the morning that we left and nice and hot when we got to Florida. Personally the heat really doesn't bother me because I am one of those people who is always cold. IMHO, I don't feel it was any more humid than it gets here in the summer in IL. I was really worried about the heat before our first August trip because of others who said it was too hot so I really don't think you will know if it's too hot for you till you try it. Just remember to drink lots of water, walk in the shade and enjoy the AC in the stores when you feel too hot.
