HONOLULU (HawaiiNewsNow) - A new north-northwest swell is forecast to bring surf to advisory levels by Friday morning.
The National Weather Service in Honolulu has issued a High Surf Advisory until 6 a.m. Saturday for the north-facing shores of Niihau, Kauai, Oahu, Molokai, Maui and the Big Island of Hawaii.
Forecasters are predicting waves of 14 to 18 feet. Beach goers, swimmers and surfers are advised to heed all advice from ocean safety lifeguards.
Beach goers should also expect strong breaking waves and shore breaks, along with strong long shore and rip currents that will make swimming difficult and dangerous.
A small craft advisory is also in effect for Kauai, Maui and Oahu until 6 a.m. on Saturday, with northeast winds up to 28 mph and rough seas from 6 to 12 feet. The NWS advises mariners, especially those operating smaller vessels, to avoid navigating in these conditions.
