Swell Summary
Surf along south facing shores will gradually decline through the weekend as the small medium to long period energy slowly fades. Currently a low in the south pacific near Australia and New Zealand will bring the potential for a moderate long period swell for Hawaii late next week.

East facing shores will also remain at small to moderate through the forecast period due to the fresh to locally strong trade winds. Flat to tiny surf along north facing shores is expected through the forecast period.
