Welcome to South San Francisco
South San Francisco occupies the basin and portions of the sides of a broad valley formed by the San Bruno Mountains on the north and the Coast Range on the west. Most of the valley faces adjacent San Francisco Bay, affording sweeping vistas, from higher levels and a definite sense of identification with the Bay. South San Francisco has mild winters and dry cool summers. The hills to the west shield the city from much of the fog that prevails in neighboring areas. South San Francisco offers its citizens a city in which to live comfortably in fine residential areas; a place of recreation in parks, swimming pools, and a marina.
