Swell Summary
An extra large, medium to long period northwest (320-340 degrees) swell which peaked early this morning will gradually decline overnight, but is expected to hold above warning levels through the evening before dropping rapidly on Saturday. The High Surf Warning has been extended through 4 AM HST Saturday for exposed north and west facing shores of Niihau, Kauai, Oahu, Molokai, and north facing shores of Maui. Additionally, a High Surf Advisory for west facing shores of the Big Island has also been extended through the same time. This swell will gradually transition to become more northerly (350-010 degrees) as it fades through the weekend. Another reinforcing northwest swell arrives Sunday into Sunday night. This swell looks to briefly bring surf heights above advisory levels. The swell will then gradually decrease through Monday before a WNW swell arrives Tuesday and peaks near advisory levels.
Surf along east facing shores will remain small, though will increase slightly tonight into the weekend as trades become re- established across the area. Additionally, some east facing shores sensitive to northerly swells may experience a slight uptick in surf heights this weekend as the fading northwesterly swell becomes more northerly. No noteworthy swells are expected for the next few days for south facing shores.
