A Small Craft Advisory is posted for all Big Island waters A Small Craft Advisory is posted for Big Island windward waters and the ʻAlenuihāhā channel through 6:00 a.m. Monday for rough seas of 10 to 15 feet. Inexperienced mariners should avoid navigating in these conditions.
**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 to double or even triple overhead or more at the best breaks on the sets early in the day.
Kona side: Surf heights are forecasted to be waist to chest high. Possibly up to head high on the sets at the best breaks.
South: Kona side and around South Point wave heights of waist to chest high are expected. Possibly up to head high on the sets at the best spots.
Shorter period mix of northwesterly swells expected to hold today mainly showing for the Hilo side. Kona side is blocked from that particular swell but catching south-southwest swell along with wind chop and a bit of wrap. Swell fades late in the day.
A recent storm near New Zealand has brought some fun waist to chest high waves for southern exposures. The swell should hold through Monday. A small new south-southwest is expected midweek. A fun sized swell is possible the middle of next week.
If the storm develops as models are indicating, we could see a west-northwest swell late this 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.
