Hot and dry. Water evaporates most quickly under those conditions and the cooler can do it's stuff. Cold and/or humid weather keeps the water from evaporating and it will not work then. So, you see a lot of these in west Texas where it is dry but almost none in Houston where it is humid.

Hot and dry, or at lease dry. They rely on adiabatic effect. Like licking the back of your hand and blowing on it. RScott
