Updated 8:24 p.m. on Jan. 26: The National Weather Service has canceled the high surf warning for Kauaʻi and Niʻihau and issued in its place a high surf advisory for north- and west-facing shores until 6 a.m. Friday.

The current large northwest swell (310 to 325 degrees) will continue to slowly decline through tonight.

Original Post: An extra large northwest swell (310 to 320 degrees) will arrive late Tuesday night that will produce extremely dangerous surf and overwash conditions along many north- and west-facing shorelines.

The National Weather Service is issuing a high surf warning that will go into effect at midnight and is forecast to last until 6 a.m. Thursday.

The forecast is for dangerous large breaking waves of between 25 to 35 feet along the north-facing shores of Kauaʻi, Niʻihau, Oʻahu, Molokaʻi and Maui.

The forecast is for 20- to 25-foot breaking waves along the west-facing shores of Kauaʻi, Niʻihau, Oʻahu and Molokaʻi.

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.
