I like the heat. But keep in mind my rides are generally an hour, commuting in each direction, and then a few years ago when the office building was closed and working from home, I take my ride mid-day now. But I likes the heat, here is a 5-year dataset, with about 1500 points, looking at effect of temperature :


If you are thinking of riding consistently in very warm weather, then consider the Canada workplace heat index system as a guide. Canada, Mexico, and USA all have the same actual workplace comfort technical details, requiring three different (and very unique!) thermometers and some other analysis, but only Canada has done a masterful job of converting all that technical detail into something you can check on your mobile device and then decide what to do (in the workplace.. You just check temperature and humidity on your phone and then read a "humidex" number of the chart below, and then the decision about how often you can work and what other support you need (like resting in a cool room or drinking a certain amount of water) is prescribed. I propagate that Canadian system everywhere warm in my working world now, because everyone can understand it in a practical senses, despite they may or may not like the effect on the workplace.




Bravo Canada !
