That's 100 degrees at nearly 0% humidity. Try 100 degrees at 90% humidity like we have in the mid-Atlantic in June and you'll feel much more unpleasant.
I’ve been in the Mojave at 112 and get in the pool and get out and be briefly chilly in the dry wind
Then it starts up
I like dry
It’s still hot admittedly but it’s far easier than 90s or 100s and drenched air saturation
Only places I’ve been where I wondered how folks survived were Gilbues northeastern Brasil and Death Valley near the bottom
120 or so
I’m old so I recall Death Valley Days and I always wondered how’d they do that in the summer ....mule teams carrying borax up outta that inferno
Plus a tribe of Indians who live there
