San Francisco's climate is characteristic of the cool-summer Mediterranean climate of California’s coast, "generally characterized by moist mild winters and dry summers. Since it is surrounded on three sides by water, San Francisco's weather is strongly influenced by the cool currents of the Pacific Ocean, which moderates temperature swings and produces a remarkably mild year-round climate with little seasonal temperature variation.

San Francisco is located on the West Coast of the United States at the tip of the San Francisco Peninsula and includes significant stretches of the Pacific Ocean and San Francisco Bay within its boundaries. Several islands—Alcatraz, Treasure Island, and the adjacent Yerba Buena Island, and a small portion of Alameda Island, Red Rock Island, and Angel Island are part of the city. Also included are the uninhabited Farallon Islands, 27 miles (43 km) offshore in the Pacific Ocean. The mainland within the city limits roughly forms a "seven-by-seven-mile square," a common local colloquialism referring to the city's shape, though its total area, including water, is nearly 232 square miles (600 km2).

Although the centralized commerce and shopping districts of the Financial District and the area around Union Square are well-known around the world, San Francisco is also characterized by its culturally rich streetscapes featuring mixed-use neighborhoods anchored around central commercial corridors to which residents and visitors alike can walk. Because of these characteristics, San Francisco was rated "most walkable" city by the website Walkscore.com. Many neighborhoods feature a mix of businesses, restaurants and venues that cater to both the daily needs of local residents while also serving many visitors and tourists. Some neighborhoods are dotted with boutiques, cafes and nightlife such as Union Street in Cow Hollow, and 24th Street in Noe Valley. Others are less so, such as Irving Street in the Sunset, or Mission Street in the Mission. This approach especially has influenced the continuing South of Market neighborhood redevelopment with businesses and neighborhood services rising alongside high-rise residences.
