Swell Summary
A series of small northwest to north-northwest swells will produce surf below April average on northern shores this week. As the current north-northwest swell fades on Thursday, a similarly sized northwest swell will fill in. This new swell will shift out of the north- northwest and hold on Friday, then decline through the weekend. A slightly larger northwest swell is expected early next week.
The current south-southwest swell will decline to summertime average heights tomorrow. A small reinforcing pulse is expected Thursday and Friday, falling back to summertime background levels during the weekend.
A belt of strong trade winds will produce an increase in rough surf along east facing shores tonight through through Friday, with the largest waves affecting Kauai and Oahu. Surf along eastern shores will be near April average statewide on Saturday and decline below average Sunday into early next week.
