I haven't spent a lot of time in that area of Arizona, from the little I remember about Phoenix, it's a big city .... and with all of it's attached "cities" it spreads out over a ver large space .... This I do know .... dry heat isn't as hard to take as wet heat, BUT 110 degrees is hot no matter what!!! You don't do a lot out of doors there from the end of April til the end of September - not until after dark anyway. It is the desert, so nights can get surprisingly cold (other than the hottest of months). Arizona has a very wide range of types of scenery from the various locations in the state, northern arizona is "high desert" and can be very cold for most of the year. Went to Grand Canyon at the end of May one year and nearly froze! Then there is the painted desert. .... Just so you know, desert can be very beautiful, but also in some places it can seem like you are never going to get any change in scenery from the miles and miles of flat land covered only by the occassional cacti. If you are used to a lot of greenery, desert isn't usually like that unless it is cultivated to be like that. Phoenix area however has a lot of palm trees and such.
