Swell Summary
The moderate size, medium period north northwest swell has reached Kauai and is filling into the central islands this afternoon. It will peak this afternoon and decline Thursday. Surf will increase to just below High Surf Advisory criteria along better exposed north and west-facing shores this afternoon. A similar sized west northwest swell is scheduled to arrive Thursday night and peak under advisory levels Friday.
Fully-developed rough east seas will persist as a result of days of strong trade winds over and upstream of the islands. Fresh to strong trades into late week will hold this wind wave-driven swell to near advisory levels. As winds begin to fall off late this week, so will this east chop heading into the weekend.
