Well, as far as tolerating the heat, to a certain extent, you get used to it. The rest of the time is spent hibernating indoors with A/C. Some homes have what we call a piggy-back system of a swamp cooler and A/C. I wish I had the swamper, although they are a pain to take care of every year. In June when the heat is high and the humidity and dewpoint aren't, a swamp cooler works great. Not so much in July and August when it's imperative to switch over to A/C.
