Swell Summary
The current south-southwest swell will produce slightly elevated surf along south facing shores today. This swell will gradually lower from tonight into the weekend. A larger, long-period southwest swell arriving Sunday will likely continue to build through early next week. A small, medium-period west-northwest swell will cause surf to trend up along exposed north and west facing shores today. This swell may lower by Thursday morning, with another small, reinforcing west- northwest swell reaching Kauai late Thursday. A slightly larger west- northwest swell may arrive this weekend. Surf along east facing shores will remain small through this weekend due to the lighter trade winds locally and upstream of the islands.
