The people were reported in the water shortly after 5:30 p.m. today, and U.S. Park Police, the U.S. Coast Guard and the San Francisco Fire Department responded, park spokesman Howard Levitt said.
A Coast Guard official said by the time the Coast Guard responded, lifeguards had already rescued them.
By 5:50 p.m. the people were on the beach being checked by fire department medics, Levitt said. Their exact condition was unknown, but "it appears to be a successful rescue," Levitt said.
