A small medium-period north swell will continue to decline today. Long-period forerunners from in incoming long-period northwest swell have reached Kauai and Oahu, and will continue to build down the island chain through the day and peak around 10 feet tonight 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 along some east facing shores due to large wind waves. Late Thursday into Friday, the swell will be reinforced and shift out of the north-northwest, likely keeping surf elevated above advisory levels. Another northerly swell reinforcement is possible on Saturday, potentially extending the advisory level surf for north facing shores. This swell is then forecast to lower Sunday into early next week.
Small short-period wind waves and wrapping northerly swell will produce small east shore surf today, followed by a rise around Kauai and Oahu tonight and Wednesday as strengthening northeast 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. Tiny south shore surf will prevail through the weekend, followed by a small pulse from the south-southwest early next week.
