The Last of Fall Color
It Almost NEVER Snows in San Francisco
San Francisco is famous for its cool. But it almost never snows here. San Francisco’s last true snowstorm (5”) happened in 1976. Before than, the last significant snowfalls in SF were in 1962, 1952, 1887 & 1882. There is a running joke here that if you want to see snow fall in San Francisco, you have to go to “The Nutcracker” ballet and wait for the final act.
Snow does fall inland all around San Francisco, in the mountains & valleys to the north, south & east. But not in San Francisco. Why is this?
The answer is the ocean. San Francisco is surrounded on three (3) sides by the water. Water maintains its temperature longer than land mass. Thus San Francisco is insulated by the ocean that surrounds it.
The eastern north Pacific Ocean is very cold. It is not suitable for swimming. Northern ocean water circulates clockwise. Unlike the western north Atlantic which circulates clockwise up from the tropics, however, our seawater circulates clockwise down from the Arctic. It is cold water. And the water is cold within a consistent range. Average seawater temperatures off San Francisco range from 53°F (11.7°C) in Winter to 60°F (15.5°C) in Summer.
And, curiously enough, this 53°F-60°F seawater range — surrounding the thin 49 square mile peninsula upon which San Francisco sits — is what makes San Francisco literally so cool year round.
It is cool here, but it’s almost never cold enough to snow.
