Winter’s Bite: San Francisco Faces Freezing Temperatures and Coastal Gales

Waking Up to a Winter Chill

San Francisco residents are waking up to some of the coldest temperatures of the season this Friday morning, February 20, 2026. Following an intense overnight squall line that brought heavy rain and powerful wind gusts to the region, the atmosphere has shifted. The rain has largely tapered off, leaving behind a piercing cold that has triggered several weather advisories across the city and the greater Bay Area.

Morning Forecast: Wind and Warnings

In the early hours, the city remains under the grip of a cold air mass. Temperatures are currently hovering around 43°F, though the residual wind chill makes it feel closer to 39°F. The National Weather Service has issued an Extreme Cold Warning and a Cold Weather Advisory, both in effect until 9:00 AM. While the heaviest rain moved through during the predawn hours, commuters should be wary of slick roads and local ponding. Morning winds remain brisk, particularly along the coast, where northwest gusts have been reaching up to 50 mph before gradually easing toward midday.

Afternoon Outlook: A Peep of Sunshine

As we move into the afternoon, the thick cloud cover is expected to break. Residents can look forward to periods of sunshine as the storm system continues its eastward track. However, the sun will do little to mitigate the chill; daytime highs are struggling to reach just 51°F. Despite a nominal 10% chance of a stray shower, the afternoon will remain predominantly dry. This is an ideal time to clear any debris left by last night’s winds, but heavy winter coats remain essential for anyone heading outdoors.

Evening and Overnight: The Big Freeze

Once the sun sets, temperatures will plummet rapidly. The evening forecast calls for clearing skies, which will allow for maximum radiational cooling. Expect temperatures to drop to a low of 42°F within the city limits, while surrounding inland valleys could see temperatures dip into the 30s. Winds will continue to diminish, leading to a calm but frigid night. If you have sensitive plants or outdoor pets, ensure they are protected before the midnight chill sets in.

Current Weather Alerts and Hazards

• Extreme Cold Warning: In effect until 9:00 AM this morning for San Francisco and the surrounding regions.
• High Surf Advisory: Coastal residents and visitors are warned of dangerous breaking waves and strong rip currents through Friday morning.
• Wind Conditions: Northwest winds are subsiding from their morning peaks, but breezy conditions will persist through the evening.
