Swell Summary

Warning level surf generated by Calvin has peaked and will trend down through this afternoon. The High Surf Advisory will continue for east facing shores of Kauai and Oahu through this afternoon, but may need to be extended as the swell propagates north through the island chain. Even though low tide will coincide with the peak surf heights, minor overwash and erosion can occur for exposed low- lying coastal areas, especially through the morning hours. South facing shores will see a slight bump in surf as the fetch from the east side of Calvin generates a small, short period south swell through tonight. Otherwise, no significant swells are expected through the weekend.
