Swell Summary

The current northwest swell will continue to decline and plateau later today at small to moderate levels. A small to moderate long period northwest swell is expected to start building in this afternoon and keep surf heights elevated over the weekend near High Surf Advisory levels for north and west facing shores. Long period forerunners have started to fill in from this new swell slowly this morning at the NDBC 51101 buoy northwest of the islands. A slight reinforcement of similar magnitude is expected from the northwest, building in Saturday, and peaking Saturday evening into Sunday. In the long range, a potentially larger northwest swell is expected around the middle of next week. Stay tuned for more details as the low starts to develop to the far northwest of the islands.

As the trade winds gradually weaken over the coastal waters and upstream of the islands, the current rough and choppy surf along east facing shores will slowly decline into the weekend and into early next week. Surf along south facing shores will decline today as the south-southeast swell eases. Surf looks to remain tiny to small through the forecast period with tiny background southerly energy.
