Mild Skies and Sunny Breaks: A Calm Close to January in San Francisco

Morning: A Cool and Cloudy Start

San Francisco is set to wrap up the first month of 2026 with a tranquil and mild Saturday. The city will wake up to a blanket of clouds and a crisp atmosphere. Early morning temperatures are expected to sit at approximately 51°F, with humidity levels holding steady at 75%. For those in the western neighborhoods, such as the Outer Sunset, expect a damp feeling in the air, though no significant fog advisories are currently in place for the immediate metro area. It is a morning best served with a warm coffee and a light layer as you navigate the early hours.

Afternoon: Chasing the Sun

As we move into the afternoon, the cloud cover is projected to break, revealing welcomed periods of sunshine. The high temperature for the day will reach a comfortable peak between 61°F and 64°F, which is slightly above the historical average for late January. This peak warmth is expected to occur between 1:00 PM and 3:00 PM. While some regional models suggest a nominal 20% chance of a stray shower, the most current data indicates that the city will largely remain dry with no measurable rain accumulation. This makes it an ideal time for outdoor activities in the Presidio or a stroll along the piers.

Evening: A Breezy Transition into February

As the sun sets, the mercury will begin its descent, settling into a low of 51°F by late evening. The breezy conditions that have characterized much of this month will persist, with average wind speeds hovering around 8 knots. While the wind is generally manageable, occasional gusts may make the air feel slightly cooler than the thermometer suggests. Skies will remain partly cloudy throughout the night, providing a quiet and stable backdrop as San Francisco transitions into the new month.
