Swell Summary
Overlapping moderate to large, medium period northwest (320 degree) and north-northwest (340-350 degree) swells will maintain advisory- level surf, with little change through Wednesday evening. A High Surf Advisory for north and west facing shores of Niihau, Kauai, Oahu, and Molokai and north facing shores of Maui remains in effect through the day on Wednesday. These swells will then gradually decline starting late Wednesday, with surf falling back below advisory criteria at that time. A moderate, medium period north (360-020 degree) swell will then move across the waters later this week.
Choppy east shore surf will continue though mid-week as locally breezy trade winds strengthen. Surf along south facing shores will remain tiny to small through the forecast period.
