I think that it's partly what you are acclimated to. I've played here in the Denver area in triple digit temps, and even in the 90's I park under a tree between shots if possible. I teed off at Palm Springs in early September at 1:00 PM, temperature was 106°. That was a long day of really bad golf.
I'll defintely be taking photos, not sure how often I'll get the posted during the trip, but for sure will get some up after. Might even put a bunch on Flickr or some other platform, and post a link here. Here are a few from 10 years ago:
Weather will be whatever it is, I'll be prepared. It'll definitely be warmer than Stoneleigh and Springfield in April were.
