Warning signs have been posted along Pismo Beach's waterfront after the sighting of a great white shark, County/Cal Fire reported.
An experienced fisherman reported seeing a shark that appeared to be the color and length of a great white shark about 10 a.m. Tuesday on the north side of the Pismo Beach Pier.
The shark was about 15 to 20 feet in length and was swimming where dolphins and seals had gathered, said Damien Juarez, a Cal Fire captain.
Seals are attracted when bait fish swim in schools just offshore, and this time of year is typically when that occurs. The sharks are drawn to local waters by the seals, one of their prey species.
Signs warning the public about the credible sighting have been posted at the beach and visitors may swim or recreate in the ocean at their own peril, Juarez said.
