Swell Summary
The current, extra large northwest swell will gradually decline tonight, but the biggest in an extended series of overlapping, winter-caliber northwest swells will arrive in the predawn hours and peak on Sunday. Surf along exposed north and west facing shores of from Kauai to Maui will remain above High Surf Warning levels tonight, followed by giant and extremely dangerous surf during the peak of the swell on Sunday. Surf will fall into the High Surf Advisory range sometime during the day on Monday and should decline below advisory levels later Tuesday. On the Big Island, surf will be at advisory levels on north and west facing shores through most of the night, followed by a rise to warning levels along western shores Sunday afternoon and night. Another large northwest swell is expected Thursday and Friday, but it is not anticipated to be as large as the current swells.
Aside from areas exposed to wrapping northwest swell, surf along east and south facing shores will remain small through Monday. As trades return, some increase in rough, short period energy is expected for eastern shores late Monday through the holiday week.
