if you like living in weather almost as hot as Africa. Personally I couldn't live anywhere where it doesn't rain at all which is why I live and love Seattle (:
it's raining in PHX right now. all day actually. in fact, it's 77 degrees right now.
The sunny climate might have a positive net effect on your creativity :)
Idk who told you that but I work better in my room or office when it's raining out, than 100degrees of sun it gets really uncomfortable to sit and program :( nevertheless I love this design good web designer for sure!
Just as you don't go outside in WA to write code when it's raining, you don't go out to write code in AZ when it's 100+. The A/C inside buildings works just fine. :) Anyway, each person with his/her own likes.
