Swell Summary
Surf along south facing shores will remain near or slightly above the September average for the next couple of days. The current small, medium-period south swell will gradually decline through Saturday, but a smaller long-period reinforcement on Sunday will maintain small south shore surf into next week.
A small north northwest swell is currently moving through the region and producing elevated surf along north facing shores, but expect it to gradually decline through late Saturday. Another short- to medium- period north northwest reinforcement could cause a slight bump in surf along north facing shores on Sunday, then decline through midweek.
