The Avila Beach pier was closed about 10 a.m. Saturday after an inspection found moderate damage from heavy surf, Cal Fire said.
The Pismo Beach pier remains closed.
In Morro Bay, crowds who had expected to walk out to the jetty at Morro Rock were told they could not go farther than the gate across the road at the east side of the rock.
The National Weather Service had issued a high surf advisory Friday that extended through Saturday, predicting waves from the southwest reaching 15 to 20 feet.
Two volunteers with the Morro Bay Police Department had the unenviable task of explaining to some angry residents that the road was closed to prevent anyone from walking to the jetty during the high tide and large surf that was breaking over the rock breakwater.
Resident Dan Nichols was angry: "I just want to do what I've always done, which is to walk out there and watch the waves. This is a common event. Everybody goes out there to watch when the waves are big. Who are they trying to protect?"
In Cayucos, families took pictures of the surf surge onto the beach and waves crashing into the pier.
