Those temps (50-70) sound real good. I’d probably melt at 88 degrees right now, but just like those who acclimate to Alaska, the same is true for newcomers to Arizona. After a few seasons of your temps, I’d adjust to that new “normal”. Our area, in the Interior, can reach temps to the 90’s in the summer months. Folks are usually surprised at that.
90’s is probably pretty hot for ya’ll. We are down on the Colorado River, if you get up into the mountains, Flagstaff, etc., it is 20 - 30 degrees cooler in the summer than it is here. Flagstaff is very popular with people down in Phoenix for summer get away homes. Before the housing market crashed the cost of housing around Flagg was getting pretty high, I don’t know how they have fared in the slowdown, certainly not as bad as Phoenix. We’ve held up here somewhat because of snowbirds taking advantage to buy winter homes vs just renting.
