>>4379906They're aren't really heatwaves since Phoenix gets 120F (49C) at least for one day every single year. I lived in the Sonoran desert for 15 years, so I have a very high heat tolerance but I can still get sunburned in 20 mins in the AZ sun. I've been in the mountains of central AZ for the last 5 years now and the weather is much nicer in the mountains, still gets 110F (44C) in summer where I'm at though (1060m ASL, 3,500ft).
