Fort Point (San Francisco)
reef
upper-intermediate

A novelty right-hand reef that breaks directly under the Golden Gate Bridge. When a big west swell refracts around Land's End, Fort Point offers long peeling rights with a spectacular backdrop. It's fickle and often crowded with locals.

The middle section of Ocean Beach offers shifting sandbars that produce hollow barrels on a strong NW swell. Peaks are less defined but can provide long rides when the banks are good. Expect powerful waves and strong currents.

The north end of Ocean Beach near the Cliff House can handle large winter swells, producing heavy A-frame peaks and long walls. Strong rips and cold water make it suitable only for experienced surfers.

The south end of Ocean Beach around Sloat Boulevard often has the most defined sandbars, producing punchy peaks and occasional tubes. Currents are still strong and the water is frigid, so only confident surfers should paddle out.
