I was in Colorado in August one year, and dang it was humid.
A friend kept telling me about Arizona and how it was a dry heat and no humidity.
For me, when I was in Phoenix, it was dang hot, dry or not dry, it was nasty hot.
I tried visiting relatives in Florida one August, that was a mistake.
I was wetter from walking to the house, to the car in the driveway, then if I had jumped into the pool, which in August, was pretty much a large hottub.
