That's an interesting comment. I've checked summer temps for a long time between central FL and here in western NY. We typically get 5-10 days of 90 or higher per summer, usually with high humidity -- FL isn't much different except it is like that for months instead of a few days in July/August.
Also, overnight temps are much higher in FL. Here in the boonies it cools off quickly in the evening. Being at the eastern base of a hill, the sun disappears around 7:15 in June, then I have 2 hours of twilight. I don't have AC and I don't even have a fan in my bedroom.
You're right ,Old Dummy, but temps in the 90s are measured more in weeks than months and if you are away from the cities = all asphault and concrete = and live rurally with a lot of trees and grass, nights drop to somewhere in the 70s even when it has reached 90 during the day. Of course, AC and ceiling fans are essential. I'm comfortable with my AC on 80 so even on 85/90 degree days AC is not overworked.
But it isn't for everyone, thank goodness, otherwise my small, quiet, inexpensive, rural community won't stay that way forever.
