Swell Summary
While small surf will prevail in the short term, increasing swell energy from the NNW is expected to bring a modest increase in surf tonight and Tuesday. Surf will then rise more significantly from Tuesday night through Friday, becoming extra large and necessitating a High Surf Warning for exposed N and W facing shores during its peak. More extra large surf along N and W shores is anticipated next weekend.
