So true to a point. What you posted RD relates to AZ for those who live in the Valley, like dezertcruzer and others who have lived in Phoenix or relatives living in Tucson.
Here in Rim Country it's better most of the time because of our elevation of 5,000 ft. We do get triple digit temps once in awhile during the Summer but most of time our hottest weather stays in the high 90's.
Just had a super thunderstorm with lots of lighting and rain. Temps. are down to a cool 64 as I post this message. <VBG>
