Left there this morning after spending 4 days. The high temp on Saturday was around 105, low humidity. Today was only around 97 or so. July is when the area gets the "monsoon" (sp?) season and the humidity gets high along with the temp.
The area is growing like crazy! It had been a few years since I was last there and there are lots of new motels and business'. Has to be a lot of new houses as well but I didn't go to any residence areas.
This would not be my choice of a place to live but then I don't like the desert. My brother lives in the Phoenix area and loves it there, likes the heat.
Go to the internet and see if you can find the Tucson Chamber of Commerce, they will have good info for you to look at.
