Swell Summary
A mix of a small, medium period northwest swell and a small, short period north northeast swell will maintain small surf for north facing shores through Saturday. Another small medium period northwest swell will fill in late Saturday followed by a moderate to possibly large medium to long period northwest swell that is expected to fill in Sunday and peak on Monday near or above High Surf Advisory criteria. Recent model guidance has exhibited a low bias, compared with observed nearshore buoy readings running higher than forecast guidance. As a result, surf heights may come in larger then currently indicated by the model output.
Surf along south facing shores will remain small through the weekend with a series of small medium to long period south and southwest swells. East facing shores will remain tiny to small through Friday except for select shorelines exposed to the current small north northeast swell. A slight uptick is expected this weekend as easterly trade winds return. In addition, a small, medium to long period easterly swell from Tropical Cyclone Priscilla in the East Pacific is forecast to arrive late Saturday into Sunday.
