A shark sighting led to the closure of about two miles of the water along San Clemente’s coastline — from about a mile north to a mile south of the pier — for about 4 1/2 hours Sunday, between 11 a.m. and 3:30 p.m.

San Clemente Lifeguard Services Lt. Rod Mellott, said four sharks has been spotted about 30 yards off the beach, prompting the closure.

The ban was lifted to a shark advisory, meaning swimmers and surfers could enter at their own risk.
