Its a dry heat. I live in the Tampa, Florida area, and once it gets past 84 degrees, I feel quite miserable. My current dwelling is a 50s ranchette with concrete block walls. The orginal Jalousie (http://en.wikipedia.org/wiki/Jalousie_window http://en.wikipedia.org/wiki/Jalousie_window) windows have been replaced, but the house has no insulation in the attic. The house had several window A/Cs, one was from the early 80s. I replaced them with a 3-zone minisplit. I cannot recommend the minisplit enough. Of course, this house is less than 1,000 sqft of A/C'ed space. You're lucky, you can just use swampcoolers. We have to use electricity to keep cool. I've been to Arizona in the summer and prefer that kind of heat.
