Searching for free events in San Francisco this week gives you a list that expires on Sunday, which is why most people do it once and give up. The more durable observation is that a large share of this city's free programming is not one-off at all. It repeats - the same Sunday afternoon all summer, the first Tuesday of the month, every weekend in the same park - and once you know the pattern you can plan any week of any year without looking anything up.
The repeating calendar tells you what usually happens; the weather and the season decide whether it is on. Tell Karpo the date and get the actual list.
Stern Grove, the summer fixture
The Sigmund Stern Recreation Grove in the Sunset is a natural bowl surrounded by enormous eucalyptus, redwood and fir, and every summer it runs a free concert series on Sunday afternoons that has been going since 1938. The programming is genuinely serious - orchestras, major touring acts, dance companies - and it costs nothing. It is one of the best free things in any American city and most visitors have never heard of it.
Popular dates now require reserving free tickets in advance, and even with one you should arrive early: people turn up hours ahead with blankets and picnics and the good spots on the slope go first. Bring layers regardless of the forecast - the grove sits in the fog belt and is routinely ten degrees colder than the Mission on the same afternoon.

Free museum days, which are the most bankable
Most of San Francisco's major museums run a free admission window on a fixed schedule, and knowing which is which is worth more than any single ticket. Several operate a free day on the first Tuesday of the month; others run free hours on a specific weekday evening, and some offer free admission to San Francisco residents on particular days with proof of address.
Two things are free without any special day at all and are worth knowing: the observation tower at the de Young in Golden Gate Park, which is free to enter and gives one of the best views in the city, and the ground-floor and stair-level galleries at SFMOMA, which can be walked into without a ticket. Between them those two cover an hour each on a wet afternoon at no cost.
The Sunday and weekend rhythm
Large sections of Golden Gate Park are closed to cars at weekends, which converts them into an enormous pedestrian and cycling space and generates a lot of informal street performance, particularly at the eastern end near Haight Street. The Great Highway along Ocean Beach follows a similar pattern at weekends. Both are free, both are permanent fixtures, and both are best on a clear day.
Sunday Streets closes a route through a different neighbourhood several times a year - the Mission, the Bayview, the Embarcadero - to cars, and fills it with stages, sound systems and street performance. The neighbourhood rotates each time, so it is worth checking which route is next rather than assuming. And the Ferry Building's farmers market runs several days a week with Saturday as the main one; walking it costs nothing even if buying does not.
The street fair season
San Francisco has an unusually dense calendar of free neighbourhood street fairs, concentrated between roughly May and October. Almost every district runs one, they close streets, they have live stages, and they range from small and charming to very large indeed. The music is usually a mix of local bands and one bigger booking, and the whole thing is free to walk into.
Alongside those sit the parades and cultural festivals that mark the city's calendar through the year, most with free public components. Checking whether your dates coincide with one takes about two minutes and frequently reshapes a weekend - some of these are among the largest events of their kind anywhere and they change the character of an entire district for a day.
The permanent free layer
Underneath the scheduled programming sits a set of things that are free every day and never need checking. The public stairways on Telegraph Hill - the Filbert and Greenwich Steps - climb through hillside gardens to Coit Tower, whose ground-floor lobby murals from 1934 are free to walk in and see. City Lights bookshop in North Beach has been free to browse since 1953.
Add the murals of the Mission around Balmy Alley and 24th Street, the view from Dolores Park, Ocean Beach at sunset, the Ferry Building arcade, and Portsmouth Square in Chinatown. None of those costs anything, none of them has an opening time to check, and collectively they are a better week than most ticketed itineraries.
Practical notes
The fixtures to remember: Stern Grove on summer Sunday afternoons, free tickets reserved in advance; free museum days on fixed days of the month - verify before travelling as they move; Golden Gate Park and the Great Highway car-free at weekends; Sunday Streets rotating between neighbourhoods; street fairs concentrated May to October. Layers at every outdoor event without exception - the grove and the park are in the fog belt and it is genuinely cold under the trees. The de Young tower and SFMOMA's ground floor are free without a ticket. Transit rather than driving for all of these; parking at Stern Grove and in the park is difficult on event days. And free at the door does not mean free inside - markets and fairs sell food.

Ask Karpo first
The repeating calendar tells you what usually happens; it does not tell you whether Stern Grove needs a reservation this Sunday or whether the museum's free day has moved. Ask Karpo what free things are actually on the day you are asking, and which of them the weather will cooperate with.
