Hot in Quincy, MA

So - what about swamp coolers. I heard they're okay for cooling off work areas which don't have much humidity. Then I read they use 'em in hot, buggy, nasty Florida to great success.
I've seen some DIY plans to make your own.
What's the professional opinion

Swamp coolers for humid climates.

An evaporative cooler does not change the actual total heat content of the air. It converts sensible heat (measured by a regular thermometer) into latent heat (heat which is hidden in the form of increased water vapor in the air...humidity).

In the desert southwest this can be very effective when the outside temperature is 110 deg and the relative humidity is 15%. The air inside can be quite comfortable. When the temperature is 110 and 30% RH, the cooler doesn't cut it for comfort.

In most parts of the country, evap coolers are not a comfort solution. In industrial conditions or in commercial kitchens they are used in humid climates since they beat not having anything and they have to ventilate anyway.
