Swell Summary
A series of small overlapping medium and long period S (170-190 degree) swells continues through Saturday maintaining surf near the summertime average along S shores. Surf then diminishes to background levels early next week as swell energy fades. Another small, long period S swell arrives by Tuesday. Short period chop continues for E facing shores through the forecast period due to persistent fresh trades. Surf along N facing shores remains nearly flat.
