Series of SSW Swells Expected
Alerts (as of 1:00 a.m.)
A Small Craft Advisory is posted for the ʻAlenuihāhā channel and waters to the west and south of the Big Island through 6 p.m. Friday.
**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: Wave heights for spots exposed to the swell are expected to be knee/shoulder high today.
Kona side: Wave heights are expected to be knee/thigh high to start. Surf will be near chest/head high by sunset.
South: Wave heights are expected to be knee/waist high to start, getting up to chest/head high by end of day.
We expect a series of overlapping south-southwest swells to move in over the next few days. Wave heights will build with the peak expected Sunday. Standout spots could be a few feet overhead on the weekend with a slow decrease through the week.
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.
