Swell Summary
Long period forerunners of a pair of NNW (330) swells have registered on the Waimea Bay PacIOOS Buoy this afternoon. At present, the bulk of wave action along the N shore remains tied to NE trades, but the swell will build until it peaks late Wednesday night into early Thursday. then briefly subsides Thursday into Thursday night only to be followed by renewed long period energy from a slightly larger and slightly more NNW (340) swell that will peak Friday into Saturday. Background medium to long period S to SSW swells will filter into the area through the week keeping surf along S facing shores from going flat. Rough, choppy surf along E shores will continue through the forecast period and will see a slight increase during the second half of the week into the weekend.
