Swell Summary
Large trade wind-driven seas will maintain high surf along east facing shores into Wednesday. Nearshore buoys have been holding at 9 to 11 feet with near 11 second periods. Fully-developed seas will continue to produce rough east shoreline surf above the 8 foot High Surf Advisory (HSA) threshold through Wednesday afternoon. As trade winds over and upstream of the islands weaken through the middle of the week, surf along eastern exposures will lower to borderline HSA levels by Wednesday evening. Expect east shore surf to be just below HSA levels late this week and during the weekend.
Surf will remain below advisory levels on all other shores through Thursday. Exposed sections of both north and south-facing shores will pull in some trade wind swell wrap and keep south shore surf near winter averages today to be followed by a decline from today through Wednesday. Moderate height, long period northwest swells will begin arriving Wednesday afternoon and evening, peaking surf along north and west-facing shores late Thursday into Friday. Fortifying secondary north swells will arrive on Friday and clip the islands. While the bulk of this northern swell energy will pass to the east of the chain, there will be enough energy to keep surf at, or slightly above, HSA heights both Friday and Saturday. These swells will diminish through the weekend and lower surf below HSA thresholds by Saturday evening.
