I enjoy the weather where we live in the Bay Area. The only issues are the cost of living, crowding and the traffic. Would visit other locations for a few weeks to escape cold months and get a change of scenery (TS).
If not here, then coastal San Diego, but same issues as above. Most of my family has migrated to San Diego County from the Bay Area, so with the exception of jobs and friends who haven't moved out of the area, we have little connection anymore to the Bay Area.
I would also consider southwest Reno and Vegas. But those are cost of living decisions and would need to leave during the excessive heat and smoke seasons.
