Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

Surf is expected to increase tonight in response to a long period NNW swell (330) with surf peaking at High Surf Advisory (HSA) levels late Saturday morning. Surf will hold at advisory levels through Saturday night, and a High surf advisory is in place for that time frame for N and W facing shores. A short period NNE swell, associated with an approaching front with gale winds, is expected to arrive Sunday, and primarily impact the surf at the western end of the state where it will mix with the longer period NNW swell. This boost will likely bring HSA level surf back to Kauai and Oahu by Sunday afternoon and will gradually fade out next week. A moderate to large swell is then possible around the middle of next week.

Surf along east facing shores will remain small to moderate through Saturday, and then be impacted by the short period NNE swell mentioned above. South shore surf will decrease tonight and remain small through the weekend.
