A moderate, medium period northwest swell (320 degrees) has filled in across north and west facing shores bringing surf heights above High Surf Advisory (HSA) criteria. This swell is expected to peak this morning, then ease into the weekend. A HSA is in effect for north and west facing shores of Kauai, Oahu and Molokai and north shores of Maui. This swell will hold today, then gradually fade and veer to the north northwest through the remainder of the weekend and into early next week and bring below average surf for December for north and west facing shores.

East shore surf will gradually build and become choppy today as trade winds increase. Expect minimal background energy for south facing shores through much of the week.

Peak monthly tides combined with water levels that are running higher than predicted will likely lead to minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible around the daily peak tide, which will be during the early morning hours. This could also magnify effects of the high surf on coastal areas along north and west facing shores around the same time frame.
