Swell Summary
Two overlapping north-northwest swells with similar heights and periods will cause surf along north and west facing shores to peak into the early evening, then will gradually fade into Friday. A High Surf Advisory will remain in effect for north and west facing shores of Kauai, Oahu and Molokai and north facing shores of Maui through tonight. A combination of north-northwest and north swells will keep surf heights elevated through the weekend, then surf heights are expected to drop into early next week.
East facing shores will remain small given the lack of trade winds upstream of the islands, but areas exposed to the north swell will see an uptick through the rest of the week. As trade winds fill in later this weekend, east shores could become rough and choppy by early next week. Surf along south facing shores will remain small through this evening due to short period wind wave chop, mainly over the western islands along the boundary, but elsewhere should remain flat to tiny through the weekend into early next week.
