In parts of Arizona yes for 1-2 days perhaps, but normally cities were asphalt is like Tucson, Phoenix, Yuma even, and the sand dunes areas/ large fields along main roads with mile after mile crops & surrounding airports average about 105F. Out in country side it is a lot cooler, for most keep bees up in hills more, though summer temps can get to 105F or odd days 110F in Jul until rains hit. But where I am what temps are in Tucson is normally about 10F cooler up in hills for most part. Unfortunately lab is in Tucson. With rain today was in 70s.But I liked the rain.
