Sunny Skies and Towering Tides: San Francisco’s Friday Forecast

A Mild and Bright Start to the Weekend

San Francisco residents can look forward to a pleasantly mild Friday, January 30, 2026, as the city experiences a gradual warming trend. Following a week of variable weather, today marks a shift toward clearer skies and comfortable temperatures, making it an ideal day for outdoor activities, provided you stay away from the immediate shoreline during the early hours. High temperatures are expected to reach a peak of 64°F, while the overnight low will hover around a crisp 51°F.

Detailed Daily Outlook

• Morning: The day begins with the sun rising at 7:15 AM. Early risers may encounter some lingering patchy fog or low cloud ceilings, particularly near the bay. This 'marine layer' is expected to burn off by mid-morning, giving way to mostly sunny skies. Temperatures will start in the low 50s with light winds out of the northeast.
• Afternoon: Conditions will be at their best between 1:00 PM and 4:00 PM. The mercury will climb to the daily high of 64°F. Winds will shift to the northwest, blowing gently at 5 to 10 mph. Humidity will decrease to approximately 62%, providing a very comfortable atmosphere across the peninsula.
• Evening: Sunset is scheduled for 5:31 PM. As night falls, the temperature will drop back toward 53°F. While the skies will remain mostly clear initially, some cloud cover is expected to return late into the night, though no precipitation is in the forecast.

Beach Hazards and Travel Alerts

While the weather in the city feels tranquil, the Pacific coastline is under a significant Beach Hazards Statement issued by the National Weather Service. A long-period westerly swell is generating large breaking waves of 14 to 19 feet. This advisory remains in effect until 9:00 AM this morning. Residents and visitors are urged to stay off coastal jetties and never turn their back to the ocean, as sneaker waves and strong rip currents pose a high risk.

Additionally, those traveling through San Francisco International Airport (SFO) should be aware of a lingering FAA Weather Advisory. Although the region is recovering from the disruptions of Winter Storm Fern, low cloud ceilings under 1,000 feet may cause some approach delays throughout the morning. Travelers are advised to check their flight status, as the marine layer can occasionally persist longer than expected, impacting runway capacity.

Finally, a full moon this weekend is contributing to higher-than-normal tides. While significant flooding is not anticipated, some minor tidal overflow may occur in low-lying areas along the Embarcadero during high tide cycles. Overall, it is a beautiful, dry Friday to enjoy everything the City by the Bay has to offer.
