Forecast for Big Island Leeward

Swell Summary

Surf along north and west facing shores will remain small this morning, then trend up later today through Thursday as overlapping north-northwest swells arrive and move through. Heights will exceed advisory levels tonight through Tuesday along exposed north and west facing shores, then potentially to warning levels Wednesday. An upward trend is anticipated once again next weekend as a large, west- northwest swell arrives. Surf along south facing shores will trend up later tonight through midweek due to a mix of fresh to strong south- southwest winds locally and a small, long- period south swell arriving. A downward trend is expected through the second half of the week. Small surf will continue along east facing shores, except for eastern shores exposed to large north swells, which is expected Tuesday.
