New Swells Expected from NE and SSW
A Small Craft Advisory is posted for waters to the south and west of the Big Island as well as the Alenuihaha channel through 6 a.m. Thursday. East winds up to 25 knots and seas up to 12 feet are expected. Inexperienced mariners should avoid navigating in these conditions.

Hilo side: Wave heights are expected shoulder/head high today. The best breaks could get up to overhead or more on the sets.
Kona side: Wave heights knee/thigh high are expected today. Spots not catching swell will be flat.
South: Wave heights knee/waist high are expected for the breaks open to the south-southwest. Trade swell mix is expected up to waist/shoulder high.
Trade winds will continue to generate short-period surf along east facing shores and combine with a mid-period northeast swell through Friday. Solid shot of north-northeast expected this weekend, building Friday night and peaking late Saturday, early Sunday.
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.
