Swell Summary
Surf along north facing shores will lower through weekend as a north swell eases. Surf will trend back up early next week as a new north- northwest swell arrives. Heights may near the advisory level for exposed north and west facing shores of the smaller islands as early as Monday, then remain up through much of the week. Surf along south facing shores will remain above average today, then lower over the weekend as a long-period, south-southwest swell moves out. Surf will rise again early next week as overlapping long-period, south- southwest swells arrive. Surf along east facing shores will remain up for Kauai and Oahu today as a moderate, short-period northeast swell and fresh to strong northeast winds continue. Expect the surf to quickly drop off over the weekend for these east facing shores.
