HONOLULU (HawaiiNewsNow) - Huge waves that battered some beachfront properties declined overnight Saturday, but remained large enough for many north and west shores to remain under a high surf advisory.

The National Weather Service issued the advisory until 6 a.m. Monday for the north and west shores of Niihau, Kauai, Oahu and Molokai, the north-facing shores of Maui and the west shores of Hawaii Island.

The west-northwest swell peaked early Saturday, with some sets around 30 to 40 feet on Oahu’s North Shore.

Some north shore sets could peak just below the 25-foot warning level threshold. Waves were forecast to remain elevated due to another west-northwest swell, slated to arrive by Sunday night.

The huge swell drew crowds of onlookers to Oahuʻs North Shore, but the waves also washed into some coastal properties during the swellʻs peak Saturday morning, just after high tide.

On Oahu, lifeguards reported making 53 rescues, most of those at Waimea Bay, by Saturday afternoon.

Lifeguards also made more than 7,000 preventative actions -- warnings to keep spectators and beachgoers safe.

Ocean Safety lifeguards reported some coastal erosion, and waves also caused some damage along beachfront properties on the North Shore.
