Swell Summary
A series of overlapping small, long period south southeast swells will hold slightly below average surf along south facing shores the next couple of days. A slightly larger swell, with more long period energy is passing over the Samoa buoy early this morning. This swell should reach the islands sometime Monday and pick south surf back up to near seasonable heights Tuesday and Wednesday.
Recent observations have verified that more southern exposures along western shorelines have and will benefit from some of this south swell wrapping around to the west.
Small wind wave swell from slightly stronger trades will maintain choppy surf along many east faces this weekend.
A small, medium period northwest swell arriving Sunday may bring surf to just above flat into early next week for north facing shores.
