Swell Summary

A northwest swell arriving today will lead to rise in the surf along the north and west facing shores. Expect this well to gradually decline after Thursday. Small surf is expected for the south facing shores through the weekend due to a continuous series of small but long period south and southwest swells. Expect a rise in the surf for the east facing shores between Thursday and Saturday as the trade wind strengthens. Surf will stay below advisory levels into early next week.
