Swell Summary
The current moderate size, medium period west northwest swell that peaked Friday is holding steady. The very slow decline of this ongoing swell through Sunday afternoon will keep Niihau, Kauai and Oahu's north and west-facing shore surf heights at High Surf Advisory levels through the afternoon. A storm complex near the date line will generate a larger, longer period west northwest (310-320 degree) swell that will arrive on this swell's heels late tomorrow into Monday. This swell will likely produce warning level surf along many north and west-facing shores Monday.
