Forecast for Big Island Leeward

HIGH SURF ADVISORY FOR SOUTH FACING SHORES

Swell Summary

Surf along south facing shores will remain up through early next week due to expected overlapping, long-period south-southwest swells. The first swell will peak today, then linger through Saturday, likely hovering around the advisory level. Expect rough conditions for most southern exposures today due to a combination of the onshore winds, swell, and periodic heavy showers moving through over the western end of the state. As this swell slowly eases later in the weekend, a fresh, long-period south-southwest swell will begin to fill in through the day Sunday. This will peak near the advisory level early next week before easing through midweek. The ongoing short-period northwest swell will keep surf along north and west facing shores up into Saturday before easing. Surf along east facing shores will remain well below average through the weekend. An upward trend is possible next week as the trades return locally and far upstream over the eastern Pacific.
