Swell Summary

The recent small, medium period north swell will slowly decline through Monday. Another medium period north swell arrival Thursday may cause a slight bump in late week surf along north-facing shores.

A small, medium to long period south swell will keep surf along south-facing shores near the September average into the first part of Monday. This swell will then gradually decline late Monday through mid-week. A couple of very small reinforcements are expected throughout the week, though surf will remain small. A slightly larger, long-period swell is forecast to arrive in the islands Friday night, boosting south shore surf next weekend.
