Negative dew points in AZ
I see that yesterday Tucson had a dew point of -2F, and Nogales was -6F. With a 101 degree high in Tucson, that corresponded to a relative humidity of 2 percent! Crazy.

Really not a problem. We run the evaporative / swamp cooler until monsoon season then switch over to AC. Ave daily temps drop when monsoon season starts. House currently 75 degree with 31% humidity and 102 degrees 12% outside. Today high suppose to be 105+. When you jump out of the pool at 2 - 12% humidity and a little breeze, It is COLD! Would rather be here! Work in the morning when it is cool. Woke to 61 this morning. Took a bike ride, worked in the garden and now watching motocross & swim after.

x2 ... Last month's electric bill for 2400 sq ft all electric home was $138, and like rocmoc, it was always in the 70's inside the house. Evap coolers work great here until monsoon season, then we switch on the HVAC. Go for a walk at first light, then work in the yard for awhile, then retreat indoors!
