What to Wear in San Francisco in December
December in San Francisco brings the city's rainy season, with highs averaging 57°F and lows near 46°F — but it's the combination of wind, fog, and frequent rain across about 11 days that makes warm, waterproof layers essential. A Gore-Tex shell or proper rain jacket paired with a mid-layer fleece and waterproof boots handles the range from a gusty walk across the Golden Gate Bridge to a rainy afternoon in the Mission District. The temperature gap between neighborhoods — SoMa and the Mission run warmer than the Sunset and Richmond districts near the Pacific — is worth accounting for.

San Francisco in December offers a distinctly cool and often damp experience, making strategic packing crucial for comfort. Average temperatures typically range from the mid-40s F (around 7°C) in the evenings to the low 60s F (around 16°C) during the day. While freezing temperatures are rare, the crisp air, combined with the city's notorious winds, can make it feel much colder. December marks the heart of San Francisco's rainy season, so expect a high likelihood of precipitation, from persistent drizzles to more substantial rain showers. Bright, sunny days are possible but often interspersed with overcast skies. The key to dressing for San Francisco in December is layers, layers, layers. Begin with a comfortable base layer, add a warm sweater or fleece, and top it off with a high-quality, waterproof and wind-resistant outer jacket or coat. This is non-negotiable. Don't forget a sturdy umbrella. For your lower half, jeans, corduroys, or other warm trousers are ideal. Comfortable, waterproof walking shoes or ankle boots are paramount for navigating the hilly streets and potential wet sidewalks. A warm hat, scarf, and gloves will be your best friends, especially when exploring waterfront areas like Fisherman's Wharf or enjoying evening activities. Prioritize warmth and protection from the elements over light fashion choices; practicality reigns supreme in December in the Bay Area.
