A reinforcement swell arriving today should keep south shore surf at advisory levels with 8-foot waves for a third day.
The National Weather Service extended a high surf advisory for south-facing shores of all islands until 6 p.m.
Forecasters say surf should be in the 6- to 8-foot range today. The south shore surf should slowly decline to the shoulder- to head- high range Wednesday and Thursday. Another south swell is predicted to roll in Friday, keeping waves elevated through Saturday.
The surf could create hazardous conditions for novice swimmers and boaters.
Surfers should enjoy decent-sized waves on all shores today.
West shores should see 5 to 7 feet waves with locally higher sets to 8 feet through Tuesday. Surf along north facing shores will decrease to 1 to 3 feet today, but another north swell could arrive Saturday.
