Trade Swell Builds, SSW Fades Today
A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as waters to the west and south of the Big Island through 6 a.m. Monday. East winds up to 25 knots are expected along with rough seas of up to 11 feet. Inexperienced mariners should avoid navigating in these conditions.

Hilo side: Wave heights are expected chest/head high today. The best breaks catching the trade swell could get a bit bigger on the sets in the afternoon.
Kona side: Wave heights knee/thigh high are expected today. Swell is fading through the day.
South: Wave heights knee/thigh high are expected for the breaks open to the fading south-southwest swell. Spots catching the trade swell could get up to waist/shoulder high.
Trade winds will continue to generate short-period choppy surf at moderate levels along east facing shores through the weekend. Other than that, there is nothing of note out of the NPAC.
Tropical Depression 6-C may bring us a bump soon. We will keep an eye on the forecast to see what develops.
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.
