Moderate, medium period NW swell gradually declines through Saturday. N pulse will move through today and Saturday in maintenance of elevated surf into weekend. A developing gale just NW of the offshore waters will send a similar moderate, medium period NW swell toward the state. This swell is advance through area waters Sunday and Monday raising surf to the High Surf Advisory (HSA) threshold. A mix of smaller, medium period N swells will arrive this weekend. These swells will maintain elevated surf along exposed N shorelines into early next week.

Surf along E shores remains small during the next several days given the lack of trades. Expect minimal background surf for S shores. S and SW exposures will see increased short period fresh swell and wind waves emanating from strengthening SW flow ahead of the approaching front. This will particularly be the case for Kauai and Oahu.
