My son, a freshman, is from Arizona. (It has been in the 80s here this week.) He said last night that he hasn’t really minded the weather, even though he had considered going to USC so is reminded of their weather. He said he had a blast this past week-end because no one wanted to go out so there was a lot going on in the dorm. It’s what you make of it. I do agree, however, that it is too bad you didn’t get to explore more on your visit.
