I grew up in Toronto and lived in Oakland for the past 6 years. Other than some smokey summers weather is near perfect. Very mild "winters", beautiful and sunny summers (much less fog than the coast or Berkeley) with only a few days >30C. Low humidity most of the year. I'm in Carson City now and its colder/hotter, still no humidity.
I was born an raised in Oakland. Live in the East Bay. Oakland has amazing weather. There are social challenges it faces now that give it substantially reduced marks.
