Swell Summary
Very small northwest to north swells are traveling around the islands. These have and will continue to generate small surf along many north and west facing shorelines through Tuesday. A larger medium period northwest swell associated with former Typhoon Malakas is timed to arrive late Tuesday and Wednesday. This approximate five foot, 10 to 14 second period northwest swell will boost north and west facing shore surf up to near head high to slightly above head high along more northern exposures going into mid week. These heights will persist through the end of the week.
East shore surf will remain elevated and choppy in the short term before subtly falling off in the coming days as the relatively longer period east swell diminishes in response to weakening upstream trades.
Recent seasonal south shore surf from the passage of a slightly larger south swell will retain these weekend heights through Monday.
