On the Border With Crook by Bourke has an interesting take on the temps in Arizona. Often 120 degrees F way into the night. This was in the 1870s.
My cousin is an evangelist and he and his wife were at the Desert Springs Marriott in Desert Springs near Palm Springs in August.
A church in lA sponsored a meeting. I chided him for using money from little old ladies to stay at a 5 star hotel, including gondolas to take you to your room.
So there were high end restaurants in the hotel. I suggested one of those and my wife an i would buy. They wanted to leave the hotel to eat. Pk. 5 PM 120 degrees outside. That’s why i don’t live on Phoenix or Palm Springs.
