Ocean Beach is a beach that runs along the west coast of San Francisco, California, United States, at the Pacific Ocean. It is adjacent to Golden Gate Park, the Richmond District, and the Sunset District. The Great Highway runs alongside the beach, and the Cliff House and the site of the former Sutro Baths sit at the northern end. The beach is a part of the Golden Gate National Recreation Area, which is administered by the National Park Service.

During the late spring and summer, San Francisco's characteristic foggy weather frequently envelops the beach, resulting in average temperatures of 50°F to 55°F (9°C to 12°C) and discouraging visitation by tourists and beach goers.^{[citation needed]} However, the beach is popular with surfers and participants in bonfire parties.^{[citation needed]} More beach-friendly weather occurs in late fall and early spring, when fog is less prevalent.
