A Marine Weather Statement has been issued by the National Weather Service for a very large west-northwest swell. The Weather Service in Honolulu says a rapidly building swell will arrive tonight and remain elevated into Thursday. They are warning of strong harbor surges and large breaking waves at harbor entrances exposed to the swell. Some locations that can expect such conditions are Kaumalapau harbor on Lāna’i.

A High Surf Warning has been issued for the north and west shores of Moloka’i and the north shore of Maui. The warning goes into effect this evening at 6:00 p.m. and is posted through Thursday at 6:00 p.m. Wave heights of 30 to 40 foot faces are expected along the north shores while 15 to 25 foot faces are expected on the west side of Moloka’i. Expect ocean water occasionally sweeping across portions of beaches, very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel difficult. Large breaking surf, significant shore break and dangerous currents will make entering the water very hazardous. Boaters should be aware of an increased number of surfers in the water.

A High Surf Advisory has been issued for the west shores of Maui, Lāna’i and Kaho’olawe from 6:00 p.m. tonight through 6:00 p.m. Thursday. Wave heights from 12 to 15 feet are expected on Maui. Surf heights of 6 to 10 feet are expected for Lāna’i and Kaho’olawe. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.

Today we should get mostly sunny skies in Maui County. We expect light and variable winds forecasted up to 15 mph. These weak winds mean a land and sea breeze pattern is likely to set up. As the land heats up, sea breezes are expected to develop which may lead to afternoon cloud cover in some spots. High temperatures forecasted to fall in the range of 78° to 83°.

Sunrise: 7:05 a.m.

Sunset: 6:09 p.m.

Looking Ahead
