Swell Summary
A small, medium-period north northwest (320-330 degree) swell will continue to decline through Sunday night, with surf along north- facing shores following suit. A medium-period north northwest reinforcement may provide another small bump in surf along north- facing shores by early morning on Monday, followed by another small reinforcing swell on Tuesday. Surf along west-facing shores will remain mostly steady through the rest of the weekend as the northwest swell influence gradually declines, but a new, long- period south southwest swell fills in.
A mix of small, medium- to long-period south swells will maintain small surf along south-facing shores for the next several days. The long-period south southwest swell described above will increase surf along south-facing shores through Sunday. Additional small, medium to long-period south swell reinforcements will arrive Sunday through mid-week.
Moderate to fresh trades will maintain rough and choppy surf along east-facing shores for the next several days.
