I always thought it was ironic that they call those evaporative
cooling units "swamp coolers" and they don't work at all here in the
swamp
They should be called desert coolers.

They call them swamp coolers because they turn anything short of a
desert into a swamp


They put humidity into the desert hot air, cooling the skin. They
pretty much fail to work when humidity reaches ~40 - 45%. Then it
feels like a swamp.

Cheaper than AC, but they need plenty of maintenance -- filters
cleaned, pumps, etc. of hard water minerals. Portable/wheeled units
are used in shops and garages.
Up here there use is pretty well restricted to "cooling stations" at
summer public events.
