**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 around head high. The best breaks open to the swell could see larger waves on the sets. Strongest early in the day.
Kona side: Surf heights are forecasted to be waist to shoulder high. Possibly up to head high, especially early in the day.
South: Southerly spots open to the west-northwest wrap should get waist to shoulder high waves. Spots open to the south-southwest wrap should get knee to chest high surf.
Our current swell is slowly fading today. The Kona side is no longer under a High Surf Advisory. The broader angle of the swell today will bring bigger waves to the Hilo side than the Kona side as it shifts a bit more out of the north.
If the storm develops as models are indicating, the next northwest swell is expected to build late Saturday into Sunday for the Kona side. A larger swell is also expected to build late Sunday and peak Monday bringing waves to the Hilo side. Another west-northwest is expected next week (19/20th).
A recent storm near New Zealand is expected to bring some fun knee to chest high waves for southern exposures. The swell should fill in Friday and peak Friday afternoon, holding through Saturday. Swell eases Sunday and through early next 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.
