As high surf buffeted north and west shores across the state, Honolulu Ocean Safety personnel on the North Shore executed 15 rescues and performed about 10,000 preventative actions on Friday.

In one incident that occurred Friday, around 2:30 p.m., Ocean Safety and Honolulu Emergency Medical Services personnel responded to three men who suffered injuries when a set of large waves crashed into them while they stood on rocks between Ke Iki Beach and Sharks Cove.

The men were able to make it back to shore on their own but, according to an Ocean Safety report, suffered “multiple abrasions from head to toe.” All three were treated by paramedics at the scene and declined transport to an emergency room.

A high-surf warning was in effect (waves measured between 10 to 14 feet) this past weekend for the north and west shores of Oahu, Kauai, Molokai and Niihau in addition to the north shore of Maui and the west shore of Hawaii Island because of an extra-large northwest swell.

A series of northwest swells generated by a complex gale low system south of the Aleutian Islands will keep surf elevated along north and west facing shores throughout the week.

The public is advised to stay away from the shorelines of affected coasts, be prepared for road closures and postpone entering or leaving channels affected by high surf during high surf warnings.

Honolulu Ocean Safety further advises people to stay away from tidepools and rock shoreline rock formations during high surf.
