Swell Summary
Weakening trade winds will result in diminishing surf along east facing shores the next couple of days. Surf along east facing shore will be rising over the upcoming weekend as trade winds are slated to strengthen. A series of north-northwest and north swells are due in this week, with the largest swell arriving Friday, which may warrant a high surf advisory for the north facing shores. Surf along south facing shores will remain small through the week.
