When the weather turns in San Francisco
Winter is the wet season here and it rains properly rather than misting. The Academy of Sciences and the de Young stand a few hundred metres apart inside Golden Gate Park, so a single trip covers two half-days. SFMOMA runs to seven floors. Musée Mécanique's antique arcade machines cost only the coins you feed into them.
San Francisco's museums, and which one to pick
The de Young in Golden Gate Park opens free to everyone on the first Tuesday of the month and free every Saturday to residents of the nine Bay Area counties. The California Academy of Sciences stacks an aquarium, a planetarium, and a four-storey rainforest dome beneath a living roof. The Cable Car Museum, housing the working winding machinery, charges nothing at all.
What to eat in San Francisco
The Mission burrito was invented here and is a specific object: foil-wrapped, rice inside, from La Taqueria or El Farolito around 24th Street. Dungeness crab season runs roughly November to June, so a July crab is not local. Sourdough owes its tang to wild yeast particular to this coast. The Ferry Building's Saturday market and Clement Street dim sum complete the list.
What first-timers get wrong in San Francisco
Summer is the cold season, with June and July fog holding the city near 15°C while September and October bring the warm clear weather everyone expects in August. Cable cars now cost $12 one way, or $18 for the Cable Car Plus day pass covering all Muni. Alcatraz and Muir Woods both need advance reservations. Never leave anything visible in a parked car.
What things cost in San Francisco
One cable car ride is $12, so the $18 Cable Car Plus pass repays itself on the second trip and covers Muni besides. Alcatraz starts near $48. Against those, the de Young is free monthly, the Cable Car Museum always, and walking the Golden Gate Bridge costs nothing. A Mission burrito stays among the best-value meals in any American city.
