Swell Summary
A more northerly 350-010 degree swell at around 4 ft 12 seconds will continue to slowly decline through today. Long- period forerunners from the next northwest swell will arrive early Tuesday, and the swell will peak at 9 to 10 ft Tuesday night and Wednesday. While the resulting surf will easily exceed High Surf Advisory levels on north and west facing shores, the peak of the swell will coincide with fresh to near gale northeasterly winds, leading to rough conditions and the potential for high surf along east facing shores due to large wind waves. On Thursday, the swell will shift out of the north- northwest and may be briefly reinforced, keeping surf elevated around advisory levels. The swell is then expected to becoming more northerly and decline late Friday into the weekend.
Small short-period wind waves and small wrapping northerly swell will produce moderate east shore surf through today, followed by a rise to around the advisory level Tuesday and Wednesday as strengthening northeasterly trade winds produce large wind waves. Above average east shore surf and rough conditions can be expected Thursday and Friday due to fresh to near gale trade winds and additional wrapping northerly swell. A small south- southwest swell will fill in late Monday into Tuesday.
