Forecast for Big Island Leeward

Swell Summary

A small northwest swell arriving early Saturday will likely cause a modest increase in surf along north and west facing shores of the smaller islands this weekend. A new moderate, long-period northwest swell arriving late Sunday is expected to gradually build, and may cause surf to approach the High Surf Advisory criteria along some north and west facing shores of the smaller islands from late Tuesday into Wednesday. Small south and southwest swells will keep small background surf along south facing shores through Saturday. A new, long-period south-southwest swell arriving Sunday is expected to cause surf to increase well above the summertime average along south facing shores for an extended period early next week. Expect the choppy surf along east facing shores to increase to above average heights from this weekend through early next week due to the strengthening trade winds.
