You have to play with the right people. You don't want to speed through a round, but you also don't want to stand around in the sun for a long time.
I think I may be in nearly the same situation you're in. I'm 6'0" right at 210lbs, used to be closer to 190 in the past. I'm 36 as well, and live in Texas, so I'm pretty close to your outside temperatures (just a few degrees cooler here on average). I think you just hit an age where things you just break down easier. I work outside a lot for my job, so I get a bit more used to it than others, but it will still get to me.
We do a lot of 7:00am rounds, try to play when it's cooler.
