Why is San Francisco Bay water so cold?
To the east, heat in the valley creates thinner air and low pressure. The valley becomes like a vacuum that wants to be filled by the heavier marine layer. It pulls that layer over San Francisco, which typically makes the city cooler than other parts of California — and the country — in the summer.

Why is the Bay Area so cool?
San Francisco also benefits from the contrast between the cold ocean current and the extreme heat of California’s Central Valley. The result is a pretty steady onshore flow of cool air, pulled in by the stifling hot air inland which rises. This also pulls the famous fog inland onto the city.
Why is San Francisco so warm?
Indeed San Francisco weather is dominated by its marine layer, directly from the ocean on the west but also from the north due to the marine air that enters the Bay through the Golden Gate gap. But in reality, the marine layer influences the coast all along California.
