Ocean Beach is one of the heaviest beach breaks in North America, stretching 3.5 miles along San Francisco's western edge where powerful Pacific groundswells unload onto constantly shifting sandbars. Winter swells regularly produce double-overhead-plus surf with a notorious "zone of death" paddle-out through relentless whitewater and strong currents generated by the Golden Gate tidal exchange. Even experienced surfers treat OB with serious respect — this is not a learner's wave.
