Long Beach beachgoers are on alert. Friday morning at least ten sharks were spotted off the coast, some coming within 50 yards of the beach.
"You are paddleboarding next to approximately 15 great white sharks. They're advising you leave the water in a calm manner," officials called out from a chopper to a man who paddleboarded his way into a dangerous situation.
Day after day this week in Southern California, Great Whites between six and ten feet long have been swimming close to shore.
"I've swam in this ocean and the bay and never ever worried about sharks. So - it's kind of stunning," said Joel Colbert of Long Beach.
Long beach officials say it's perfectly normal. They saw a similar numbers of sharks, around this time last year.
"The fish are thriving so the sharks are coming to feed on the fish," said Cpt. Cameron Abel of the Long Beach Fire Dept. Marine Safety Division.
But authorities are still taking precautions, keeping the beaches open- yet issuing a "Shark advisory."
And that advisory will stay in place- until lifeguards go a full day without seeing a shark.
