That swamp cooler is useless in August

If you buy or rent a house in April and they tell you the swamp cooler is all you need, don't believe them.

An evaporative cooler works great in April, May and most of June, but once the monsoon hits and the humidity rises, that box on the roof is no good. You can keep pumping water through the pads and pushing air through the wet pads into your house, but you're adding humidity to hot, humid air. That won't cool your house anymore.

Things will work again after monsoon, maybe in late September. And yes, it will still be hot enough to need the cooler.

In the meantime, get thee to an air-conditioned movie theater.
