Most likely wind, although, as a San Francisco resident, I have never heard of this happening. Fog usually moves inland from the sea, then burns up during the afternoon, and comes back in during night.

Warm, moist air being advected over the cold California current.

Fog happens when moist air is cooled. Air can contain a certain amount of water, and the amount depends on the pressure and the temperature; the higher the temperature, the more water can be absorbed in the air.

We call this "relative humidity"; when the relative humidity is 100%, it cannot hold any more water at that temperature. When you then chill the air, the relative humidity goes even higher and the air becomes "supersaturated". At this point, water vapor will condense into tiny water droplets and cause fog.

Why does San Francisco so much fog?

San Francisco has a lot of fog because the ocean current cools the air along the coast, causing water vapor in the atmosphere to condense and form fog, small cloud droplets near the earth's surface. San Francisco has few storms because the Pacific Ocean moderates its temperatures. Air pollution may contribute some dust, but the cool temperatures from the current are the overwhelming influence.

Can you see the stars in San Francisco?

You can see the stars if there is no fog and no light pollution. However, there is hardly a night without fog, and I've never seen San Francisco without light pollution, so I guess the answer would be no. However, drive an hour north and there are some pretty clear places where you can see the stars pretty well.
