Swell Summary
Surf along S shores is trending down as S to SW winds ease. A new long period south swell will then arrive late tonight and Tuesday giving an extended boost to S shore surf through late this week.
A moderate short-period W swell associated with the recent kona storm is affecting N and W facing shores today, but surf remains below the advisory threshold. The short-period W swell will lower tonight and Tuesday while a new medium-period NNW swell fills in. This NNW swell could elevate surf to near the advisory threshold Tuesday night and Wednesday. The swell then shifts more N and lowers Thursday into the weekend.
Surf along E facing shores will remain well below normal through late week as trades over and upstream of the islands remain disrupted.
