Swell Summary
Overlapping west-northwest to north-northwest swells will produce surf around High Surf Advisory levels for exposed north and west facing through Friday. The latest west-northwest swell will produce surf just below advisory levels along north and west shores of Kauai and Oahu during its peak tonight, with gusty winds along the front producing rough conditions on Kauai and possibly on Oahu closer to daybreak. Overlapping pulses of west-northwest swell, similar in size, will arrive later Wednesday and keep surf near advisory levels, mainly on Kauai and Oahu, through Friday. A sharp downward trend and shift out of the north-northwest is expected during the weekend, followed by a potentially large northwest swell next Tuesday.
East shore surf will remain below seasonal average through the week, though a brief increase is possible on Kauai tonight due to strong northerly winds behind the front. Surf along south facing shores will remain very small through the week.
