Forecast for Big Island Leeward

Swell Summary

Surf along exposed north and east facing shores will remain rough due to a mix of locally-driven wind waves and a large medium- to long- period north-northeast (020 deg) swell moving through. Surf will hold at warning levels for eastern exposures today, then lower to advisory levels tonight as the north-northeast swell slowly eases. Surf along north and west facing shores will trend up late Sunday through early next week as a long-period (forerunners expected to arrive through the day Sunday) northwest (310-320 deg) swell arrives. This swell will peak on Monday (advisory to near warning- level surf), then ease Tuesday through the second half of the week. Models show the next significant northwest swell arriving late next weekend.
