Swell Summary
Existing N (350) moderate, medium swell has been modeled to slowly subside through today. After hovering around 2 feet above guidance throughout the day, NDBC buoys 51001, 51101, and 51000 have shown signs of subsiding N swell late this afternoon. Meanwhile, the Hanalei PACIOOS buoy still indicates High Surf Advisory conditions going strong at press time. Surf should begin to noticeably subside during the next few hours. However, the High Surf Advisory will be extended through tonight mainly to capture the trailing end of the high surf period during the first half of the overnight period. Surf along west facing shores remains slightly elevated with the influence of the north swell during the next couple days. Surf along E shores increases today and Wednesday in response to short period trade wind swell over and upstream of the islands. Surf then declines in concert with weakening trades during the latter half of the week. However, east facing shores exposed to the north swell will continue to see some wrap during the next couple days. South shore surf will remain small with mainly background south and southeast swells during the next 7 days.
