Easy. Scorching hot desert! While I admit that it never hit 120 at my home town, it got to 117, and a few 113 to 115 F readings are certainly expected to occur in most summers. I was more than ready to live in Ciudad Juarez for the rest of my life, but hot, dry weather was certainly not the most pressing issue we were facing from 2007 til 2011 when we decided to leave. Summer there lasts from mid March til the first week of November, if you count summer to be in the mid Eighties and above. The rest of the year? Well, Juarez then becomes a freezing, arctic town for a few weeks 8according to the locals :), but it does get cold, down to the low teens at night. And a wind-channel and an adequate setting to film some dust-bowl movies.
I certainly have been to places hotter than this, so I would never complain. Try living in Hermosillo, Sonora, which does get to 120 F and usually stays above 90, even 95 at night within city limits. (They measure out near irrigated farm fields on the airport) But after a few years you easily cope. Watch your urine color and drink at least as much to keep it yellow, stop eating too much protein in summer, and never shut off your cooling system for months, not even at night. Weekend activities are usually heading to A/C steeped malls, hanging out inside under the cool breezes of A/C until the sun goes down or heading out really early in the morning - and then sweating it at my wife’s family farm with no A/C. Usually you do not sweat, unless working out. The air is too dry, at least when it is above 100. Heading to the pool was never an option, for the sun will burn right through the strongest sunscreen, water in this town is preciously scarce and does not get changed and maintained well in the pools that do exist and there would be more people in there than water. My wife and daughters sometimes would bathe in irrigation wells, no bathing suits, making for a scene you would expect in the Middle East. But that is what the local customs of that farming community were, where this still held true: What is not for sale is not on display!
This means that you do not run around half naked even when it is really hot. Which is smart, too. The hot sun will get more heat load into your body than you can lose through sweating. So cover yourself up and wear some sort of hat. In all these years I would not even own shorts, and neither did my wife. Loose-fitting clothes from cotton or traditionally - linnen, and maybe a short-sleeved shirt or bl
