Following a closure due to a shark activity in the area, ocean waters in the San Clemente area were reopened Tuesday, but a shark advisory remained in effect warning swimmers to enter the surf at their own risk.
The shark advisory will remain in place until at least 8 p.m. Tuesday, “pending no additional shark sightings,” according to city officials.
A shark knocked a surfer off of his board off the coast of San Clemente late Monday morning, prompting authorities to close the water to swimmers and others on the busy Memorial Day holiday. City officials said at the time the closure was due to “confirmed aggressive shark behavior” in the water in the vicinity of T-Street Beach.
The beaches remained open, but water access was closed.
City Councilman Chris Duncan told CBS2 that surfers reported the activity to lifeguards, who reviewed surveillance footage and found video of the surfer being knocked off his board.
According to CBS2, officials from the Long Beach State University shark lab were consulted, and they determined the culprit was likely a juvenile great white shark.
No injuries were reported.
