How Often Does It Snow?

Keep in mind that snow occurs when the temperature is too low, and the air has a significant amount of moisture. In San Francisco or Northern California, there is a high moisture level, but the Pacific Ocean warms the air even before reaching the land.

Therefore, snow is rare, with only 10 measurable or significant snow accumulations recorded since 1852. The main reason is that the moist air isn’t cool enough.

When it comes to how often it snows in San Francisco, experts used to predict that significant snowfall at sea levels and even flurries in San Francisco can happen every two decades. However, as the world becomes warmer, this predicted return rate of snowfall increased to 30 years and higher.

When Was San Francisco’s Last Snowfall?

On the night of the 25th of February, 2011, it was reported that San Francisco experienced a light snowfall., but not enough to be measured. Thus, as of writing, the last recorded significant or measurable snowfall happened 46 years ago.

This historical event occurred on the 5th of February, 1976, and covered the Twin Peaks, Mount Davidson, and Mount Sutro with approximately five inches of snow. At higher elevations, such as Mt. Tamalpais and Mt. Diablo, they were covered with more than five inches of snow.

Since the snow fell downtown, the city was covered with snow, from trace amounts to one-inch accumulations.

Other Recorded Snowstorms in San Francisco

Since the answers to “Does it snow in San Francisco?” and “How often does it snow in San Francisco?” are yes and rarely, let’s go back in time and see the other times the city experienced snow.

While the city also experienced flurries and snow accumulation of less than an inch, it’s usually only above sea level, meaning the snow only accumulated at the mountain ranges. As such, we only included snowstorms with a snow depth of one inch and above.

That said, on the 30th of December, 1856, the city experienced an unusually low temperature, with the lowest reading of around 39 degrees Fahrenheit (3.8 degrees Celsius). It also recorded a 63.5-millimeter or 2.5-inch snowfall accumulation.

This incident made reporters wonder whether the season is starting to change due to innovations, which we’ve already been calling climate change in the last few years.

However, the next recorded heavy snowfall in San Francisco occurred almost 30 years after. Specifically, on the 31st of December, 1882, it snowed for five straight hours, leading to a snow accumulation of 90 millimeters or 3.5 inches. Then, on the 7th of February, 1884, the city recorded a depth of 1.5 to 2.0 inches of snow.

Following this event is the snowiest and wettest day in the history of San Francisco, as of writing. On the 5th of February 1887, the snow started falling around three in the morning and continued for hours.

Ninety-four millimeters (3.7 inches) of snow blanketed the city’s downtown. Meanwhile, the highly elevated western parts were covered with up to 177.8 millimeters (seven inches) of snow.

Golden Gate Park also had one of the deepest snow accumulations but was damage-free after the snowstorm. On the contrary, tree branches crashed while the Conservatory of Flowers’ windows were broken due to the accumulated, mounded snow’s heavy weight.

The next snowstorm that followed was on the 3rd of March, 1896, with only an inch of accumulation.
