A high surf warning is in effect until Monday at 6 p.m., according to the National Weather Service.
Forecasters say the warning is for the north and west facing shores of Kauai, Oahu and Molokai. On Maui, the warning covers the north facing shores.
Surf for north facing shores is expected to be 20 to 25 feet, lowering to 15 to 20 feet by the evening. West facing shores should be 15 to 20 feet Monday morning and 10 to 15 feet by the evening.
Forecasters expect very strong breaking waves, strong longshore and rip currents, and ocean water to occasionally sweep across portions of beaches. Breaking waves may occasionally impact harbors making navigating the harbor channel dangerous.
Large breaking surf, significant shore break and dangerous currents may make entering the water very hazardous. Forecasters say anyone entering the water could face significant injury or death.
Boaters should be aware of increased numbers of surfers and body boarders utilizing the harbor channel to access surfing areas.
