Fact. I played in a football game in Hays KS, 116 on the turf an no humidity. The whole 2 weeks before at camp in Emporia was upper 90's with 80% plus humidity, soaked to your underwear and socks every practice hard to breathe. Go out for the game, not a drop of sweat on me the whole time! Felt amazing, never felt hot in the least. Could breathe even. Turns out that night I was quite dehydrated, lots of cramps and headaches, whoopsy
Edit: That's me agreeing that 92 with no humidity is no biggie, I was in Moab in July and it was 1teens. Miserable on those rocks radiating heat up into you. My "116 isn't hot compared to 96 with humidity" statement was talking about an extreme example, not pleasure wheelin
