Coast Guard crews and firefighters Tuesday morning responded to a Pacifica beach where a man reportedly was swept into the surf by a large wave while he was walking on the rocks, officials said.
At about 7:45 a.m., crews responded by air, water and on the ground, searching for the man, fire officials said.
North County Fire was being assisted by two Coast Guard helicopters and a Coast Guard life boat.
The waves were coming in at between 12 and 14 feet, officials said.
No further details were immediately available.
