Swell Summary
A large to extra large, long-period northwest (310-330 degrees) swell is finally starting to show signs of a very slow downtrend, but is still running a foot or two higher than model guidance this afternoon. Therefore, the High Surf Warning for most north and west facing shores of the smaller islands has been downgraded to a High Surf Advisory (HSA), in effect through Tuesday afternoon. The HSA for exposed west facing shores of the Big Island has been extended through Tuesday afternoon as well. The swell will slowly ease Tuesday through midweek. A small, medium-period, northerly (350-010) swell is forecast to build in Thursday night, peak Friday, then ease slowly over the weekend.
East shore surf will remain below seasonal averages through the rest of this week as wind speeds remain on the lighter side. South shore surf will remain seasonably small as well, though a small bump is possible around midweek.
