swamp cooler effect.The craziest thing I found was in mid-summer, it can be 115F. If you step out of a pool, you instantly freeze!!... and I mean shivering cold! It's so dry that the water instantly evaporates and cools like crazy. I couldn't fathom that until I experienced it. Back east, on the other hand, one steps out of the ocean on a hot day and gets hot again quickly.
