A series of long period south and southwest swells will keep surf along south facing shores near to slightly above the September average through Thursday, before gradually lowering Friday through early next week. Small surf will prevail along north facing shores through the remainder of the work week, with a small bump from a northwest swell expected this weekend. Another small but slightly larger northwest swell is possible Tuesday and Wednesday of next week. East shore surf will remain well below normal today, rise to near seasonal levels Thursday through Saturday as trade winds ramp up over and upstream of the islands, then lower a notch Sunday into early next week as the trade winds ease.
