Swell Summary

The current south swell will slowly decrease over the next several days. Overlapping small, long- and medium-period south swell energy will keep small surf along south facing shores through the week. The next boost in south swell energy will arrive and fill in from Tuesday to Wednesday at around 2 to 3 feet with an 18 second period. This swell will peak on Wednesday, just below south shore advisory thresholds, and then slowly decline through the end of the week. Trade wind swell energy will continue to keep elevated surf heights along all east facing shores through the coming week. Surf along east and southeast facing shores could become especially rough and choppy Thursday into Friday as Lowell passes by to the south.
