PACIFICA (KRON) — As temperatures begin to climb and people expected to hit the coast this weekend to beat the heat, police are warning beachgoers about a possible shark roaming in the waters off Pacifica.

According to police, a white shark was spotted at around 10 a.m. Friday morning off of Linda Mar Beach. A surfer in Pacifica said he was only 20 feet away from a great white shark on Friday.

“While shark sightings are not frequently reported, we do realize the Pacific Coast is part of the natural habitat for white sharks,” police said.

The surfer who saw the shark Friday morning didn’t want to go on camera but he told KRON he’s positive of what he saw.

He said the great white breached the waves and that it looked like a movie, and he got out of there fast.

Last October, the U.S. Coast Guard spotted a group of great whites about 100 yards out to sea from Pacifica. There were 20 of them swimming together.

The Pacifica Police Department is asking the public to report shark sightings at 650-738-7314.

Spencer Blake was in Pacifica to talk to people who were at the beach, just 24 hours later. His report is in the video above.
