I was in phoenix (actually peoria) first week of august for a softball tournament. flew out from burbank @ 75F (it was cooler than usual). came out of phoenix airport waiting for my ride and couldn't breath. if you like a furnace by all means move to phoenix. I needed an iced towel around my neck the entire time I was out doors. the two evenings were were out on the softball fields there was a mist trapped above. actually felt more uncomfortable as it was a steam bath.
