Meh. I grew up there, in the rain and the rain and the rain and the rain and the rain...
Now I live in the desert west of Tucson. I will admit it was a little warm this afternoon at 116, but to me a few nice sunny January afternoons will make up for it.
June is hot in the SW.
I lived in that land for a number of years. It was a remote area probably 75mi west of you.
They will be OK.
I was north of AJO. Hottest is always last 2 weeks of June and then the humidity flows in from GOM. Storms from the Rim or even the Tucson area do happen, but not often.
Gila Bend is sitting on top of a huge reservoir of water.
