Swell Summary

The northwest swell, currently producing north shore surf near the advisory level, will gradually decline this afternoon and may be briefly reinforced by an overlapping northwest swell on Sunday before fading on Monday and Tuesday. Another small northwest swell is possible mid week.

Strengthening trade winds will produce increasing, short period seas over the next several days. This trade wind swell will become large and rough Monday into Wednesday and will be mixed with a short period north-northeast swell. During this time, surf along east facing shores may reach the advisory level.
