Swell Summary

While the fetch of trade winds to the E of the islands is somewhat limited, short- and medium-period wind waves/swells will be arriving from the NE and NNE over the day or two, due to the strong high, and the strong gradient between it and a slow-moving, gale-force low off the U.S. W coast. This will result in increased seas, with rough and choppy surf along shores exposed to the N and E. Surf along exposed E facing shores may become large enough to warrant a High Surf Advisory by tonight or Tuesday. Very little swell energy from the NW is expected this week, but a small pulse of swell will persist through today, with another pulse possible Thursday and Friday.
