January is San Francisco’s quiet season — cool, rainy, and thin on tourists — but the indoor arts calendar is genuinely strong that month. If you are visiting in January, the events below are the reliable annual ones; confirm exact dates on each organization’s site, since they shift year to year.
Golden State Warriors (Chase Center)
The NBA season runs through the winter, so the Warriors have home games at the Chase Center in January. Schedules and opponents are set per season — check the Chase Center calendar when you book. Games are the most expensive ticket in town, so buy ahead.
SF Sketchfest
SF Sketchfest is the city’s long-running comedy festival, spread across January in several venues (often the Marines’ Memorial Theatre and others). It mixes headliners, local troupes, sketch, improv, and stand-up. Tickets for marquee shows sell out, so plan early if a specific act matters.
FOG Design+Art Fair
FOG Design+Art takes over Fort Mason for a long weekend in January, pairing a modern-art fair with talks by designers, architects, and artists. It is the design-world event of the SF winter; day tickets and talks are separate, and the talks draw a specialist crowd.

MLK Day and Noir City
The Martin Luther King Jr. Day observance (the third Monday of January) includes a program at Yerba Buena Gardens honoring King. Separately, the Noir City film festival — the largest of its kind in the U.S., run by the Film Noir Foundation — screens classic and rare noir at the Castro Theatre, usually in January. Both are fixed-date or scheduled annually, so verify the year’s calendar.

Golden Gate Kennel Club Dog Show
The Golden Gate Kennel Club Dog Show brings roughly 2,000 dogs across 175-plus breeds to the Cow Palace, with conformation and agility. It is a two-day January event and one of the easier family outings that time of year.
Conclusion
January in San Francisco is best approached as an arts-and-indoors month: comedy, design, film, and basketball, plus the MLK observance. Book Sketchfest and FOG tickets in advance, check the Warriors and dog-show dates on their sites, and pack for rain — outdoor plans are unreliable. If you want a festival with better weather, the separate SF festivals and summer events pages cover the warmer months.
