What to Wear in San Francisco in January
January in San Francisco is the wettest month, averaging 46–57°F with about 11 days of Pacific storm precipitation — a seam-sealed waterproof shell with a hood, Merino wool mid-layers, and waterproof ankle boots are the functional standard for the Ferry Building, Mission District, and the Golden Gate Bridge approaches. The Pacific wind off the Bay and on the bridge's exposed span drives the real-feel temperature well below the air reading, and the persistent drizzle soaks through light rain jackets over the course of a sustained day outdoors.

Navigating San Francisco's January weather requires smart packing and a strategic approach to layering. While not brutally cold, January is typically one of the city's chilliest and wettest months. Expect average daytime temperatures to hover around 57°F (14°C), dipping to about 46°F (8°C) in the evenings. Precipitation is highly likely, with the city receiving a significant portion of its annual rainfall during this period. While persistent fog is less common than in summer, sudden gusts of wind can make even mild temperatures feel much colder. The key to dressing for San Francisco in January is versatility. Begin with a comfortable base layer, add a warm sweater or fleece, and top it off with a waterproof and windproof jacket. A compact umbrella is also essential. Given the city's iconic hills and pedestrian-friendly layout, comfortable, waterproof walking shoes or boots are non-negotiable. Don't forget a scarf and perhaps a light hat to combat the evening chill and bay breezes. Embrace layers you can easily shed or add as you transition between sun-drenched streets, foggy districts, and indoor attractions.
