Swell Summary
Large trade wind-driven seas will maintain east shoreline surf at or above the 8 foot High Surf Advisory (HSA) threshold through this afternoon. As trade winds over and upstream of the islands weaken, surf along east facing shores will decrease, becoming small by Thursday. Increasing trade wind swell and an arriving northerly swell at the end of this week and into the weekend will provide a bump in east shoreline surf.
A northwest swell will begin arriving this afternoon and evening, peaking surf along north and west-facing shores late Thursday into Friday. The secondary north swell will arrive Friday and, in addition to the returning trade wind swell wrap, may boost surf heights to, or slightly above, HSA heights from the end of this week into the weekend.
Surf along south-facing shores continues to pull in some trade wind swell wrap, with an expected decline today with the easing trades. A southwest swell will fill in late today through Thursday before slowly declining through the weekend, which will keep south shore surf from going flat.
