110° is child's play, when I lived in Phoenix in 1990 it hit 122°!
Still, I'd take a dry 100 over 90 with high humidity as is common in the midwest.
I've visited Pima in that kind of heat, one tends to stay under large aircraft for the shade. And thankfully, it's largely unpaved desert, so it could be worse.
Plus there are shaded picnic areas and Pepsi machines.
One thing that's fairly new...the parking lot is covered so your car stays cool. The roof structure consists of solar panels.
