A High Surf Advisory is posted for the east facing shores of Maui and Moloka’i through 6:00 a.m. Wednesday. Surf of 6 to 10 feet is expected. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.

Small Craft Advisory is posted for all Maui County waters through 6 a.m. Tuesday. Northeast winds up to 30 knots and rough seas up to 15 feet are forecasted. Inexperienced mariners should avoid navigating in these conditions.


A Gale Warning is posted through Tuesday morning at 6:00 a.m. for the ʻAlenuihāhā Channel. East winds up to 35 knots and rough seas up to 18 feet are forecasted. Mariners without the proper vessel and experience should remain in port until gale conditions end.

    North: Wave heights are expected to be waist to chest high today. The best breaks could see a few sets shoulder to head high.

    West: Wave heights waist to chest high at the breaks open to the northwest swell early on. Otherwise, pretty flat conditions are expected today for spots shadowed from the swells.

    South: Chest to shoulder high waves are expected today. Best breaks could get shoulder to head high sets.

    Screen Shot 2015-04-20 at 9.22.36 PMOur current northwest is expected to hold through the first half of this week. It should fade out by Thursday. Another boost is expected early next week out of the northwest.

    Combo of southwest and south-southwest swells expected to hold through Thursday and fade out Friday into the weekend. Next week is looking pretty quite out of the southern hemisphere.

    Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
