Each cell: significant wave height / largest wave in about an hour. Above 2 ft: caution.

Wave heights are model estimates from forecast wind, not measurements, and actual waves can be 25% or more higher. Check the marine forecast and the water at the launch before you go. The decision to go out is yours. Full text
