> 100-110F there is pretty comfortable, so long as you can get some shade. I agree with you there, but I'd also mention that in Phoenix, it's not the heat that will kill you, it's the sun. The deserts in Arizona and eastern California have the most intense sun in the US. If you can't find shade, for example while hiking in the desert, the climate in Phoenix is brutal. It's also very easy to get dehydration and low blood sodium, because sweat evaporates so fast you don't even realize you're sweating. This all makes the climate very dangerous - it's not as uncomfortable as heat with high humidity, but it will sneak up and kill you. One third of all heat related deaths in the US happen in Arizona.[1] 1: https://apnews.com/article/record-heat-deadly-climate-change-humidity-south-11de21a526e1cbe7e306c47c2f12438d https://apnews.com/article/record-heat-deadly-climate-change...
