I'm south of Houston on the Gulf Coast. Today we're at 50% humidity. I can make a lot of water if I'm in this area. I'm sure if I headed north (can't really go south without swimming) I would be dealing with lower humidity, but the AWG's can produce water anywhere but the production time will be affected by the humidity of course. Enough to survive day to day is really the goal so you could do that pretty much anywhere.
