Swell Summary
The current tiny northwest (320-330) swell will dissipate today and will be followed by another tiny north (360-010) swell building Tuesday and peaking Tuesday night. Moderate, medium period northwest (300-310) swell developing from a developing low northwest of the islands will build Wednesday, eventually peaking Wednesday night into Thursday. Another moderate but longer period northwest (310-320) swell is expected next weekend.
Small long- period south swells will continue to linger over the next few days. Breezy southerly winds will bring an increase of rough and choppy surf along south facing shores Tuesday into Wednesday. A slightly larger, long period south (190) swell is expected to arrive late Friday, bringing average to slightly above average surf to south facing shores next weekend. Surf along east facing shores will gradually decline through the upcoming work week as the winds veer to the south.
