New Southerly Swell Expected Soon
Alerts (as of 1:00 a.m.)
A Small Craft Advisory is in effect through 6 a.m. Thursday for all Big Island coastal waters (except windward waters).
**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 trade swell are expected to be around waist/head high.
Kona side: Wave heights are expected to be ankle/knee high today or even flat.
South: Wave heights are expected to be knee high or less today. Strongest around South Point with trade swell filling in.
Trade swell will bring surf to northeast exposures but onshore breeze will pick up quickly during the day to chop it up.
Quiet in the North Pacific at this time. A possible swell may be generated in the Eastern Pacific later this weekend or early next week. If everything stays on track we could see some energy building around the 9th and 10th.
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.
