High surf warning for north and west facing shores of Kauaʻi and Niʻihau

The National Weather Service has issued a high surf warning for north and west facing shores of Kauaʻi, Niʻihau, Oʻahu and Molokaʻi, and north facing shores of Maui until 6 a.m. Saturday.

A large northwest swell (320-330 degrees) will build across the islands Friday.

Dangerous surf of 20 to 30 feet is forecast along north-facing shores and 14 to 22 feet along west facing shores of Niʻihau, Kauaʻi, Oʻahu and Molokaʻi. Maui will see surf heights along north facing shores building to 20 to 25 feet by Friday afternoon and evening.

After the peak occurs Friday afternoon and evening, the swell is expected to slowly drop to advisory levels on Saturday.

Expect very strong breaking waves and powerful currents. Waves breaking in channel entrances may make navigating the channels dangerous.

Stay away from the shoreline along the affected coasts. Be prepared for road closures. Postpone entering or leaving channels affected by the high surf until the surf subsides.
