The National Weather Service has revised an earlier high surf advisory and now says to expect surf of 16 to 20 feet on the north-facing shores of Niihau to Maui.

West-facing shores of those islands will likely see surf of 12 to 16 feet, the Weather Service said.

The advisory will remain in effect until 6 a.m. Saturday.

The high surf is expected to peak this afternoon and evening and to decrease over night.

The high surf advisory will remain in effect until 6 a.m. Saturday.

Elsewhere on Oahu today, look for surf of 3 to 6 feet along east-facing shores and 2 to 4 feet along south-facing shores.

Outlook through Wednesday, Feb. 11: The current northwest swell will slowly subside Saturday through Tuesday. Strong trade winds may produce advisory-level surf along east-facing shores starting early next week.
