One person was rescued and one person was missing after the pair were swept into the water off the San Mateo County coast Sunday afternoon, authorities confirmed.
Sheriff's officials said that around 3:15 p.m., they responded to a call at Pescadero State Beach where a man and woman had been searching for mussels on the rocks when a wave swept them away.
The man was rescued and transported by ground to a local hospital with a hypothermia-related condition as swimmers and helicopters searched for the missing woman, Cal Fire said.
Near Santa Cruz Harbor, big waves flipped multiple boats and sent about 20 people into the water, 12 of whom were children, authorities said. Ultimately, all the people were rescued, and no injuries were reported.
In Marin County, a San Jose man was missing after he was swept into the water by the high surf at Marin Headlands, officials said.
The searches and rescues came amid high surf and king tide warnings, and officials advised people to use extreme caution if going near the beach.
