My parents lived in Tucson in the early 1940s when there hardly anyone there.
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.
They came there from Nebraska with high humidity in the Summer months, so maybe the “dry heat” felt good to them. I don’t know, it was before I was born.
I live in high desert dry heat where it commonly hits well over 100 for days on end and it is much more tolerable than the low 90s and high humidity of east Texas where I spent my Summers as a child.
