This time of year your going to want to be up on a mountain somewhere, or its going to be a pretty uncomfortable sticky campsite. Stay out of washes at the very least.
Near Tucson, the closest cooler elevation would be in the Catalinas, very near town. Next closest would be down by Patagonia, then the Chiricahuas about 2 hours to the sw.
The monsoons can be a bit violent, so be careful. Personally, this time of year I'd go get a deal on a nice hotel with a concrete floor. They do make some pretty good deals this time of year, cause most normal well thinking people are somewhere else.
