What people ask before booking
How many days do you need in San Francisco?
San Francisco needs three days for the city itself and five if you want the wine country or the coast. It is compact enough to walk and hilly enough that the map underestimates every route.
What is the best month to visit San Francisco?
September and October — The actual summer, and the clearest skies of the year. April and May — Green hills, long light, before the fog arrives.
