When we were living in San Francisco, we didn’t see fog as regularly as I thought we would. But that’s mainly because of where we lived.
San Francisco has more micro-climates than any place I’ve ever seen. Tiny pockets of the city seemed to experience completely different weather patterns than ones adjacent to them.
Downtown was kind of in the middle. The western side seemed to hold fog a bit more than the eastern side, where it tends to taper off, pretty much disappearing before hitting East Bay.
This image shows just the tippy-tops of the skyscrapers touching the limits of the fog, while the rest of the city is in the clear. Definitely not as thick as the fog on the Golden Gate Bridge.
