Swell Summary

A moderate medium period north swell has begun to rise and will peak later today before steadily declining Monday. Surf along east facing shores will remain small today, except for shores exposed to the north swell which could see a slight rise. As the trades strengthen early this week, short period wind waves will bring elevated seas. South facing shores will continue at small levels as a series of small, medium to long period energy will persist over the next several days.
