I always wondered how people lived in AZ in the summer before air-conditioning was common. It was AC certainly that encouraged the massive growth in AZ population.
I was raised in Phoenix before Most people could afford air conditioning when I was younger Phoenix was surrounded by Farms yes it is hot during the day but every night it would cool if you couldn’t stand the heat you would soak a sheet and water and pinion up with close pins in front of a fan so the work like an evaporator cooler before we are rich enough to afford a cooler
Same goes for all the Southern states. You had to be some kind of tough to live down here before the invention of a/c.
Phoenix and Tucson are at the lowest altitude in the state. Phoenix is dead center in the Valley of the Sun. The humidity is low so the heat-related illnesses sneak up on you. But touching anything with a matte-black surface during a summer day is like touching a red-hot stove. You could easily fry an egg on the pavement.
In the mountains and Grand Canyon areas, it’s much cooler. But still dry.
Arizona will cut you if you aren’t careful! ...But it’s still a great state!
