I now live near San Francisco. I used to live in AZ. In AZ it was 60's in the winter and 110 to 120 in the summer. This summer in S.F. we only had the air conditioner on once, but we've had the heat on twice. In the mornings it's been low 60's. Too cold for me right now. It finally warmed up for about a week and it's mid-September.
