I have been around misters in non-desert environments and you can get some relief but you need to have appropriate expectations. A "really nasty day" here would be around 95 with a 77 dewpoint. This works out to about 55% relative humidity. There is some "room for evaporation", which will cool the air, but not much. Dew point is a measure of the actual amount of moisture in the air and it is difficult to evaporate much more water into the air, which is what misters try to do. The relative humidity might appear to be low but it is difficult to get it much higher than about 60% with a temperature of 95. I won't bore you with the details. With dewpoints in the upper 70s, there is little evaporation from your skin, which is why it feels so hot. Again, a mister will drop the air temperature a little bit but there is not much potential. If you get a mister, I would recommend that you buy it at a place where you can return it if you don't see a benefit.

In the summer, there is no way I can be outside on the lanai any time of day or night unless I get something like this. Being in the pool is fine, but wanting to sit on the lanai and read or nap, is impossible. We are from WA state where it doesn't get much over 70o most of the time. Does anyone have such a fan or know of one they would recommend?
Once in Las Vegas, I sat by the pool and read and the overhead misting system was great for cooling off. Thanks for any help.
