A long-period northwest (305-325 degrees) swell is quickly building down the island chain and is expected to peak tonight through early Monday. Surf has been upgraded to a High Surf Warning (HSW) for most north and west facing shores of the smaller islands through Monday. The swell will gradually ease Tuesday through midweek as it shifts out of the north.
Choppy east shore surf, already below seasonal averages, will drop further through the rest of the weekend and remain small through the upcoming week as wind speeds remain on the lighter side. South shore surf will remain seasonably small, though a small bump is possible around midweek.
