Sea state according to the Beaufort scale:

0 Sea like mirror 1 Ripples with appearance of scales, no foam crests 2 Small wavelets, crests of glassy appearance, not breaking 3 Large wavelets, crests begin to break, scattered whitecaps 4 Small waves becoming longer, numerous whitecaps 5 Moderate waves, many whitecaps, some spray 6 Larger waves, whitecaps everywhere, more spray 7 Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind 8 Moderately high waves; edges of crests begin to break into the spindrift; foam is blown in well-marked streaks along the direction of the wind 9 High waves; dense streaks of foam along wind; crests begin to topple, tumble and roll over; spray may affect visibility 10 Very high waves with long overhanging crests; foam in great patches blown in dense white streaks along wind; sea surface takes a white appearance; tumbling becomes heavy and shock-like; visibility affected 11 Exceptionally high waves (medium sized ships may be lost to view behind waves); sea covered with long white patches of foam lying along the wind; everywhere edges of crests are blown into froth; visibility affected 12 Air is filled with foam and spray; sea completely white with driving spray; visibility seriously affected

Because this is an official scale to measure wind, I used the scale descriptions, and added the sea state descriptions in long description. See https://en.wikipedia.org/wiki/Beaufort_scale, https://www.metoffice.gov.uk/weather/guides/coast-and-sea/beaufort-scale For the long description, the wording given by ESAS was used.
