Forecast for Big Island Windward and Southeast

HIGH SURF ADVISORY FOR NORTH FACING SHORES

Forecast for Big Island Leeward

Swell Summary

North swell (360 degrees) energy has been slow to fall along many north-facing shores and has remained steady through the early morning hours. Thus, the High Surf Advisory (HSA) for all islands (except Lanai and Kahoolawe) has been extended through Noon today to account for this slowly declining swell. A similar size, slightly longer period northwest swell will begin building in late Saturday into Sunday morning. This will lift surf to near or slightly over HSA levels as it peaks out late Sunday going into Monday. Another much larger north northwest swell associated with a cold front is timed to reach the islands around Thanksgiving and increase surf along north and west-facing shores to possible High Surf Warning thresholds. East- facing shore surf will remain small through the day but will be on the rise over the weekend and into early next week per strengthening trades. The recent south swell will be fading from tonight through Saturday morning.
