Advisory Level Swell Maintains Wave Heights Today
A Small Craft Advisory is posted for most Big Island waters (except right off of South Point) through 6:00 p.m. Wednesday for southwest winds of 20 to 30 knots and rough seas up to 16 feet.
A High Surf Advisory is posted through 6:00 p.m. Wednesday. Surf from 8 to 10 feet is expected along west facing shores. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.
A Gale Warning is posted for all off shore 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: Surf heights are expected head high or more. The best breaks open to the swell could see larger waves. Some spots could get up to double overhead on the sets.
Kona side: Surf heights are forecasted to be head high or more. Possibly up to a couple of feet overhead.
South: Southerly spots open to the west-northwest wrap should get head high to overhead waves. Breaks not open to the swell will be much smaller at ankle to knee high.
Our current swell is maintaining wave heights today. This large swell prompted a High Surf Advisory for the Kona coast which is still in effect. The Big Island is shadowed from this swell but will still see decent size. The Kona side should see the swell fading Thursday as the swell shifts from a more northwest direction. Meanwhile, the Hilo side is expected to maintain surf heights through the end of the week.
If the storm develops as models are indicating, the next west-northwest swell is expected next week (18/19th).
A recent storm near New Zealand is expected to bring some fun knee to chest high waves for southern exposures Thursday and Friday.
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.
