A 29-year-old San Francisco man died while surfing at Ocean Beach on Sunday evening, fire officials confirmed.

Emergency personnel responded around 6:30 p.m. to the surf rescue near Great Highway at Rivera Street and began CPR on the surfer, who was identified Monday by the Medical Examiner’s Office as Jason Zumbo. Zumbo did not survive.

Ocean Beach is considered one of the most dangerous beaches in the U.S. for its notoriously powerful waves.

Ocean Beach — unlike Stinson Beach in Marin County, which is also under the management of the National Park Service — is not a designated place to swim and therefore has no lifeguards on duty.

In response to the deaths of two 17-year-olds on April 16 who drowned after being swept out from the shoreline, Supervisor Eric Mar called for a safety hearing at a May Board of Supervisors Public Safety and Neighborhood Services Committee to discuss what improvements could be made at Ocean Beach to prevent future drownings.drowningMedical Examiner's OfficeOcean Beachsurf rescuesurfer
