Update: High surf advisory canceled for Kaua‘i and Ni‘ihau

Update at 4:05 p.m. Dec. 29: The high surf advisory that was in effect for Kaua‘i and Ni‘ihau has been canceled as surf has dropped below advisory levels.

Original post: A high surf advisory is in effect till 6 p.m. Saturday for Kaua‘i and Ni‘ihau.

An extra-large north-northwest 340 degrees swell combined with a large north swell 350 degrees will produce advisory level surf for north- and west-facing shores.

This swell will transition to a more northeasterly direction tonight and Saturday allowing surf heights to lower for west-facing shores and increase for exposed east-facing shores. Large breaking waves of 18 to 22 feet along north-facing shores will drop to 16 to 20 feet in the afternoon.

The strong breaking waves and currents will make swimming dangerous.
