I've heard people from Florida say that it would be impossible to survive in summer without an air-conditioner. Is this true? I guess the humidity is just ridiculously high?
The population of the entire state was very low until after the invention of air-conditioning. The population roughly doubled between 1940 and 1960.
Generally though, the heat is pretty bad, particularly if you're stuck inside with no AC. I've had a couple rounds of that and its certainly not comfortable at all. Honestly I'm sick of southeastern weather.
