Residents across the San Francisco Bay Area woke up to an unusual sight on Saturday morning - snow dusting the highest peaks in the region, including Mount Hamilton in Santa Clara County, Mount Diablo in Contra Costa County, Mount St. Helena in Napa County, and Saratoga Summit in the Santa Cruz Mountains.

Why it matters

Snowfall in the Bay Area, especially at lower elevations, is an extremely rare occurrence, with the last measurable snow in many parts of the region dating back decades. This unexpected winter weather event has generated excitement and wonder among locals, as well as some concerns about potential impacts on infrastructure and travel.

The details

According to meteorologists, the snow was the result of a cold front moving through Northern California, bringing temperatures low enough for precipitation to fall as snow rather than rain on the region's highest peaks. While the snow accumulation was minimal, typically less than an inch, it was enough to create a picturesque winter wonderland across the Bay Area's iconic landscapes.

  • The snow began falling on the morning of Saturday, February 18, 2026.
