Crisp February Sunshine: San Francisco Prepares for a Mild and Bright Tuesday

A Bright Break in the Winter Season

San Francisco residents can look forward to a refreshing break from the typical winter dampness today, Tuesday, February 3, 2026. As the city moves deeper into the first week of February, high-pressure conditions are bringing a stretch of dry, mild weather that stands in pleasant contrast to the usual seasonal chill. While February in the Bay Area often fluctuates, today’s outlook remains remarkably consistent with the clear and sunny conditions seen over the past few days.

Morning: Fog and Fresh Temperatures

The day begins with a cool, crisp morning as temperatures started in the low 50s. Typical for this time of year, patchy fog has been reported in the early hours, particularly around the North Bay and near the shoreline of the San Francisco Bay. Commuters are advised to stay cautious during the early morning hours, as visibility may be reduced in low-lying areas. However, this marine layer is expected to burn off quickly, giving way to clear blue skies by 10:00 AM. For those heading out early, a light jacket or layered clothing is recommended to handle the 52°F morning start.

Afternoon: Peak Sunshine and Mild Warmth

As the sun reaches its peak, the city will experience its warmest temperatures of the week. Highs are projected to reach between 65°F and 66°F, which is several degrees above the historical February average for San Francisco. Light onshore winds will keep the air feeling fresh and prevent any excessive warming, creating a perfect atmosphere for outdoor activities at Golden Gate Park or along the Embarcadero. The humidity is expected to settle around 62%, ensuring a comfortable, dry heat throughout the afternoon hours.

Evening: Cooling Skies and Transit Alerts

The evening will see a steady dip in mercury as temperatures retreat toward a low of 48°F to 52°F overnight. Skies will remain mostly clear initially, though some partial cloud cover is expected to return after sunset. Travelers should take note: the Federal Aviation Administration (FAA) has signaled that low clouds or increasing ceilings could impact operations at San Francisco International Airport (SFO). A potential ground stop or delay program is possible after 4:30 PM, so passengers flying out this evening should check their flight status before heading to the terminal.
