Swell Summary

A northwest swell will gradually ease through today. A larger north-northwest swell should begin to fill in tonight and peak Friday, with surf likely below advisory levels along exposed north and west facing shores of the smaller islands. This swell will slowly fade into the weekend. Surf along south facing shores will remain elevated through the second half of the week as a long-period south swell moves through. This should peak today before fading into the weekend. Surf along east facing shores will remain small and choppy due to the fresh/strong trades locally and just upstream of the state.
