There is a saying in the United States about Phoenix that says, “At least it is a dry heat.” Actually, that is not really true. It can get rather humid in southern Arizona, at least compared to dry heat in areas like Denver or Salt Lake City. Their proximity to the Colorado River valley and the Gulf of California plus their lower elevation of only 1,086 feet makes the saying, “It is a dry heat” rather ridiculous.

The heat in Phoenix can be dangerous and deadly with not only the heat, but also the heat index with a higher humidity. It can easily be above 100 degrees at midnight in Phoenix, which means a warm start to the next day.
