Winter’s Chill Bites Back: Rain and High Surf Grip the City

Morning: A Damp and Cold Commute

San Franciscans waking up this Thursday, February 19, 2026, will be greeted by a gray and damp start to the day. Following a wet beginning to the week, a cold air mass has settled over the Bay Area. Expect light rain and scattered showers throughout the morning hours, with a high probability of precipitation hovering around 90%. Temperatures will start in the low 40s, making for a brisk morning where heavy coats and umbrellas are non-negotiable.

Afternoon: Chilly Skies and Scattered Showers

As the day progresses, the steady morning rain is expected to turn more scattered. While some brief breaks in the clouds may occur, the city will remain mostly overcast and decidedly chilly. Afternoon highs are projected to struggle to reach 50°F, likely peaking between 49°F and 51°F. Winds from the west and southwest will persist at 10 to 20 mph, adding a significant bite to the air. Those heading out should prepare for a damp and breezy afternoon as the region sits between passing storm cells.

Evening: Rain Redevelops Under Cover of Darkness

The brief respite in the afternoon will likely end as night falls. Forecast models indicate that rain will redevelop and become more widespread after midnight. Overnight lows are expected to dip to 42°F. South-southwest winds may increase in intensity, with gusts potentially reaching up to 30 mph in exposed coastal areas. It is advised to secure outdoor items and prepare for a wet Friday morning ahead.

Critical Warnings: High Surf and Coastal Hazards

The National Weather Service has issued a High Surf Advisory effective through Friday morning. Coastal residents and visitors should be aware of the following conditions:

• Large Breaking Waves: Waves of 18 to 22 feet are expected along the Pacific Coast.
• Sneaker Waves: There is an increased risk of sneaker waves that can pull unsuspecting individuals into the sea.
• Dangerous Conditions: Swimmers and surfers are urged to stay out of the water, and everyone should stay off jetties, piers, and coastal rocks.

While San Francisco proper will see mostly rain, a Winter Weather Advisory remains in effect for higher elevations in the surrounding region, where snow is expected to accumulate above 3,500 feet. For those staying in the city, the primary concerns remain the persistent cold and the hazardous coastal surf.
