Best time to go to San Francisco

Peak Season:

San Francisco's peak season lands in June to September, and November. June through August can be both hot and humid, but this peculiar climate begins to dissipate in September, and by November, the city is a beautiful place to reside. <br />Despite occasional uncomfortable weather, tourists still gather in this destination in order to take part in the many events, like the LGBT parade in June, the San Francisco Shakespeare Festival in August, and the Festival of Lights in November.

Shoulder Season:

May and October are a mixed bag in terms of climate. Many tourists avoid the city during these times, making inexpensive flights to San Francisco easier to find. If you do not mind the erratic weather, this is an excellent time to play on Fisherman's Wharf, tour Alcatraz, or have dinner and a movie at the Foreign Cinema restaurant.

Off Season:

From December to April crowds thin out and the weather becomes exceedingly brisk and damp. Do not let the weather deter you, however, as this is a great time to take part in one of the many indoor activities, like catching a show at the Great American Music Hall or shopping at the Embarcadero Centre.
