I grew up and lived in the extreme heat and dry air of the southwest most of my life. It was very tolerable.
But now I'm retired and dying in the heat and humidity of the southeast. It is insufferable.
Current heat and humidity on my farm here in Florida is 90 and 92. You can cut the air with a table knife.
It’s better in the Midwest where they have four seasons: green, brown, white, and mud. But I still prefer dry if it’s gonna get hot. Nothing like being out in shirtsleeves at 2am after a party just relaxing on the patio with the folks who’re staying over; looking at the starry sky, and its 72 degrees with a slight breeze.
