Updated at 4 p.m. on Sunday: A high surf advisory has been extended till 6 a.m. Monday along shorelines of Kaua‘i and Ni‘ihau.

Large breaking waves of 12 to 16 feet along north-facing shores and 8 to 12 feet along west-facing shores are expected.

Updated at 3:54 p.m. on Saturday: The high surf warning has been downgraded to a high surf advisory for north- and west-facing shores of Kaua‘i and Ni‘ihau till 6 a.m. Sunday.

Surf along exposed shores has decreased and will continue to slowly lower through the remainder of the weekend as a significant northwest swell fades. Heights should dip below advisory levels by Monday.


Surf of 18 to 24 feet is expected this evening, lowering to 12 to 16 feet by Sunday.

Updated at 4:25 p.m. on Friday: A high surf warning has been extended till 6 a.m. Sunday for north- and west-facing shores of Ni‘ihau and Kaua‘i.

Surf of 25 to 35 feet is expected through Saturday, lowering 20 to 25 feet by late Saturday.


Minor coastal impacts with periodic overtopping of the roadways are anticipated late tonight into Saturday morning during high tide times.

Updated at 6:11 p.m. Nov. 23: The high surf warning for north- and west-facing shores of Kaua‘i and Ni‘ihau has been extended until 6 a.m. Saturday.

Original post from 8:26 a.m. Nov. 23: A high surf warning is in effect from noon today until 6 p.m. for north- and west-facing shores of Kaua‘i and Ni‘ihau as a large northwest swell is expected to build in today before extra large reinforcements will cause a sharp rise in swell height tonight and into early Friday morning.


According to the National Weather Service in Honolulu, surf of 25 to 35 feet is forecast in the warning areas. Surf will likely reach warning levels late this afternoon, peak tonight and hold through the day Friday.

The public should expect very strong breaking waves and powerful currents. Waves breaking in channel entrances could make navigation dangerous.

Overtopping of roadways along the affected coastlines is possible late tonight into Friday morning because of high tide and the peak of the swell.

The public is advised to stay away from the shoreline along the affected coasts, be prepared for road closures and postpone entering or leaving affected channels until the high surf subsides.
