Spent 3 weeks in Florence area when my daughter graduated high school. I think it was late June. We rented an air bnb. The owner asked us to use it sparingly as electricity costs, I guess, were exorbitantly expensive. The cost of the place was very reasonable so we barely touched it.
Easily the hottest and most uncomfortable I have ever been was that trip. And I have lived in Phoenix for 20 something years so that's saying something.
Won't touch on the massive quantities of mosquitos and no screens to be had anywhere.
