Among the reasons to pack your bags for a trip to San Francisco this January are an extraordinary fancy-dress ball, the Chinese New Year Parade, and some exciting art events. And it's the best time of the year to see a beautiful sunset.
San Francisco Weather in January
How cold is San Francisco in January? It's one of the city's chilliest months, on average. But that may not seem cold by your standards. High temperatures will be in the upper 50s most of the time.
January is also the wettest month in SF. But rainfall is far less constant than temperature, year to year, varying from a little to a lot. When it does rain, it's not uncommon to get the entire month's rainfall in just a day or two. It's unlikely to snow, though. The last significant snowfall was in 1976, and there was light snow in 2011.

What to Pack
Some visitors from colder climates think San Francisco feels like summer in January, and they run around in short-sleeved shirts just because they can. To avoid being instantly identified as an out-of-towner, resist that urge.
If rain is predicted, you should be prepared, Umbrellas are hard to carry on crowded sidewalks and don't protect from wind-driven raindrops. Still, a warm, waterproof jacket with hood is a better choice, especially when it's windy, or you're surrounded by people.
While January is one of San Francisco's cooler months, a mid-weight jacket (or a bit more) will be enough on dry days. Locals often wear gloves, a hat, and a scarf in the mornings.
