PS: Your AC lower air temp below your target room temp, and extracts water because that air is limited to 100% humidity. The air is then heated by your house which is how relative humidity drops. Aka they don't extract anything at 20% humidity and they extract everything over some % that varies based on outside temp.
Maybe El Paso, but the rest of the state is pretty humid unless you compare it to Florida or Georgia et al.
But yes, I generally think that people forget that most of the Texas population lives within the effects of the Gulf of Mexico. It's fun watching the transition from green to brown when flying.
