Outlook through Monday January 07: A new small northwest swell will build today, then peak well below advisory levels tonight. A larger northwest swell will build Tuesday and Tuesday night, then peak at or near advisory levels Wednesday through Thursday. Persistent moderate to strong trades will result in elevated surf along east facing shores through much of the week, with advisory level surf possible at times, Tuesday through late in the week.
