Swell Summary
A series of large to extra large northwest to north-northwest swells will continue to move through the islands over the weekend, peaking on Sunday. A High Surf Warning (HSW) for north and west facing shores of Niihau, Kauai, Oahu, Molokai and north facing shores of Maui has been extended through 6 PM Sunday. A High Surf Advisory (HSA) for north facing shores of the Big Island has been extended through 6 PM Sunday. More swell energy is reaching west facing shores of the Big Island than expected this afternoon, resulting in higher observed surf there. The HSA for west facing shores of the Big Island has therefore been upgraded to an HSW, which is in effect through 6 PM Sunday.
Surf may briefly dip below advisory levels late Saturday afternoon and evening before the largest of the swells arrive late Saturday night into Sunday. This swell is expected to bring the largest surf of the season to north facing shores on Sunday.
Aside from areas exposed to wrapping northwest swell, surf along east and south facing shores will remain small through the weekend. East shore surf will trend up early next week as the trades over and upstream of the islands strengthen.
