I live in a climate similar to a high desert. It's hot here in the summer, but the humidity is low. In fact, the advice in this article about the humidity being lower in the morning or evening is completely wrong for where I live. Exercising in high heat and low humidity can be fairly comfortable as long as you're producing enough sweat to cool your body.
Also, because this is a dry climate, cotton is wonderful. I always wear a cotton cycling cap under my helmet. I can dip it in any water (including non-potable ditch water, or not-very-tasty park water fountain water), put it back under my helmet, and my body cools quickly as the air flowing through my helmet dries the cap. It's wonderful!
Like the Texans said, exercising in heat is possible in dry climate. Ease into it, and be very conscious of how you feel. Triple digits is no time to let your pride dictate how long you workout.
And I know this is nitpicking, but applying sunscreen will not keep you cool. You should do it, but the only "coolness" benefit is that it sucks to be the sun if you already have a sunburn.
