I hear that! I lived in Florida for a short time, close to Tampa. But I found surprisingly that the humidity in the summer months was comparable to Toronto (at it's worst).
In the country where I live now the high in the summer is usually about 90. But we've been having an unusually cool month with highs of 68. But in the city where I grew up, highs can be as much as 95 - 104 with humidity.
