Swell Summary
A new north swell is expected today which will boost surf, peaking just below advisory levels tonight. This swell could elevate surf along east facing shores with northerly exposure. A series of small north and north-northwest swells are then expected Sunday through Wednesday. Small, mainly background south and southeast swells are expected through Monday with a slightly larger south swell expected to fill in Tuesday and Wednesday.
