Swell Summary
Surf along south facing shores will be small over the next few days with mainly background south and southeast energy. A small to moderate, long-period, south southwest swell will build Saturday into Sunday and help boost south shore surf heights back up to near or above the September average.
Surf along north facing shores should see a small increase tomorrow as a short period northerly swell fills in. This small bump is expected to peak on Friday out of the north to north- northeast direction, followed by a short period north northwest swell this weekend. Moderate to locally strong trades near and upstream of the area will lead to choppy conditions along east facing shores over the next several days. A slight increase of windswell is expected over the weekend due to a fetch of strong winds northeast of the state.
