LOL - I think the weather is perfect where you live (So San Francisco), sonarrat!
The East Bay is definitely warmer and has less fog, but Berkeley can get awfully chilly & foggy in/near the hills... I've attended concerts at the Greek Theater (near UCB), and they're always COLD. Oakland has really nice weather, and is usually sunny and warm in most spots. And if you want to live west of the bay, it's always foggier near the ocean but windy near the bay. My neighborhood is right on the bay near Candlestick Park, and we're typically the sunniest & windiest part of SF. Boy, it was
really blowing today!

For actual warm weather, you have to head way inland or south - i.e. San Jose or Concord.
Oh, and our "foggy season" is usually during the late summer-early fall. Winters can be surprisingly nice and sunny (or rainy), and springtime is when we get the serious wind & occasional rain. But yes, it's typical for summer to be the coldest/foggiest, and locals know to ALWAYS carry a jacket.
