I play games with a guy who does concrete work in Arizona, he mostly works at night.

I lived for a while in Tucson, Arizona.

Days could be brutally hot ( easily over 100 F ), but there was little humidity. My transportation was a motorcycle ( with additional heat radiating off the engine ), so mid often feel a little uncomfortable, but it was definitely livable.

Interestingly, homeowners often used evaporative ‘swamp coolers’ instead of AC. A big benefit of low humidity.
