Summer temperatures always hover in the mid to high 30's C. (100's F.) and the best solution that I've found is to drink plenty of water (cool, but not freezing) and if I commute mid-day, I wet a bandana and place it in the fridge until it's nice and cool, but not frozen. That helps with the risk of heat stroke.

I might try that....

This is surprising effective, whether it is on a long ride, a hike, or working in the yard. Just soaking a bandana in cool water will make you feel instantly cooler if you feel you are overheating.

Stay hydrated, don't worry about it. Don't be scared of the heat, just be prepared and acclimate.

Though some people just plain deal with it better than others. My stepdad is the first person in his family to live outside of Iceland in literally hundreds of years. My little (half) sister doesn't deal with the heat nearly as well as I do, despite being born in, and growing up in Texas.

Seriously? You're aware that people spend months riding in those temperatures with no issues, right? Even touring?

Yea wow i'm just a complete moron, huh?

Well it makes me wonder wtf you're concerned about.

I took the road bike out the other morning and wore a jersey with a full zipper. It was unzipped a good bit due to the heat. That afternoon I made a store trip and wore one of my Gildan DryBlend (50% Cotton/50% Polyester) high viz tee shirts. The afternoon temps were a good ten degrees higher but I was much more comfortable in the Dryblend shirt than I had been, even in cooler temps, with the 100% polyester jersey.

I am concerned about inflation pressures as the tubes get older. In the past, riding in high heat lead to poor inflation retention. In the cold i have had warm air inflated tubes lose the pressure from the gas in the tube contracting (getting cold). Both of which increase rolling resistance, and increase the chances of a pinch flat.
