Swell Summary
A moderate to large, long period, northwest swell will enter the coastal waters late tonight into Sunday morning, then swiftly rise and peak during the afternoon. Surf heights along north and west facing shores should once again breach HSA criteria. This swell will fade though Monday. The next moderate, long period, northwest swell will keep surf elevated Tuesday through mid- week for north and west facing shores.
Rough, choppy surf along east facing shores will hold through Sunday. Additionally, some east facing shores sensitive to northerly swells may be experiencing a slight uptick in surf heights through Sunday as the fading north northwesterly swell becomes more northerly. No noteworthy swells are expected for the next few days for south facing shores.
