For most of the year, deserts can be surprisingly cool and comfortable; just stay away during the summer. In the American Southwest, nearby mountain ranges provide quick relief from the heat and a great variety in life zones with extreme contrasts in flora and fauna.

I am just back from my usuak summer gig in South Dakota and i was surprised at how cool and wet SD was this year. Usually summer temps in Hot Springs top 100 degrees, just like in Tucson and other desert areas. I can remember 100 plus degrees when a kid vacationing in Brainerd, MN, as well.

When it is hot, wherever you are, start early, lie low and take a siesta during midday, and stay cool.
