Swell Summary
While the fetch of trade winds to the E of the islands is somewhat limited, a steady supply of short- and medium-period wind waves/swells will be arriving from the N through NE for the next several days, primarily due to the gradient between the high 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. High surf along exposed E facing shores is expected, and a High Surf Advisory (HSA) is in effect starting this morning. Surf heights along N facing shores will be similar to those on E facing shores, but differing criteria between shorelines means peak surf heights along N facing shores will remain below HSA heights. Very little swell energy from the NW is expected this week, with increased potential for long-period NW swell to arrive late next weekend.
