Swell Summary
Surf along north and west facing shores will continue to slowly trend down into this evening as the current north-northwest swells fade. A series of small to moderate, long-period northwest to north- northwest swells (320-340 degrees) will fill in throughout the week, keeping surf elevated. The first of these swells (320-330 degrees) is expected to fill in tonight, before peaking Monday morning, producing above average surf. The next swell (330-340 degrees) will peak late Tuesday before fading Wednesday. A larger, moderate, long-period swell (330-340 degrees) could produce advisory level surf for north and west facing shores late Wednesday into Thursday. And yet another moderate, long-period swell (330-340 degrees) will fill in Friday through Saturday, bringing another chance for north facing shores to see advisory level surf.
Background, medium- to long-period south to southwest swells will continue to filter into the area through the upcoming week, keeping surf along south facing shores from going flat. Rough, choppy surf along east facing shores will persist into this evening before dropping a notch Monday as trades trend down slightly through mid week. Then rough, choppy surf will return for the latter half of the week at the trades strengthen.
