Manually produced forecasts of Sea State are produced twice a day. These charts depict the expected significant sea state with a 1 meter height contour interval. Where appropriate, relative maximum and minimum wave heights are centrally depicted with a sea state value in a box. Also, included are forecast winds (knots) greater than 15 kt. Maximum significant wave heights analyzed does not take into account higher individual wave heights. Remember that significant wave height is defined as the average height of the highest 1/3 of wave heights observed.
