Swell Summary
A diminishing north northeast swell will maintain small surf along north and northeast facing shores through Saturday. An area of strong to near gale force winds along the southern periphery of a broad low near the west Aleutians will be focused along a northwest great circle path directed at the islands. This small, short to medium period northwest swell is scheduled to arrive and boost north and west surf late Saturday night into Sunday morning, hold this surf through Monday with a decline on Tuesday. A subtle increase in east facing shore surf will hold through early next week in response to trade wind wave swell propagating from fresh easterlies over and upstream of the islands. The arrival of a series of small, long period background south swells will provide a minor boost to south shore surf. A slightly higher, long period south southwest swell arriving Tuesday may hold southern coast surf to near seasonal levels through the middle of next week.
