I mean I'm not making this up.
You said:
and July and August in San Francisco have TERRIBLE weather: fog, rain, and cold.
The link you quoted said:
Acturally, the average summer temperature range from 60 to 75 degrees, and evenings in the summer can be rather cool, with temperatures dipping to the low 40s, but never quite to the freezing point. One bright point: rain is rare in the summer in San Francisco.
Come on, that is not terrible! Sheesh!

As you said, this is a micro-climate, different parts of the city have different temps and climates. The western half is usually foggy in the summer, eastern half is usually sunny and 60-70s constantly during the day, every day. To each his own I guess.
Come here in the fall, there is less fog. This is true of most of the north coast actually. Fall is the sunniest time of the year.
