From time to time we see people posting about the conditions that they have encountered.
Do people count the Swell height as well as the wave height?
Or is it just that I am not as game as some of the posters here.

BEAUFORT LEVEL WIND SPEED SEA STATE AND WAVE HEIGHT LEVELS
FORCE 0 LESS THAN 1 KNOT SEA LIKE A MIRROR
FORCE 1 1 - 3 KNOTS WAVE HEIGHT .1 M(.25 FT.); RIPPLES WITH APPEARANCE OF SCALES, NO FOAM CRESTS.
FORCE 2 4 - 6 KNOTS WAVE HEIGHT .2 - .3 (.5 - 1 FT.); SMALL WAVELETS, CRESTS OF GLASSY APPEARANCE, NOT BREAKING.
FORCE 3 7 - 10 KNOTS WAVE HEIGHT .6 - 1 M (2 - 3 FT.); LARGE WAVELETS, CRESTS BEGIN TO BREAK, SCATTERED WHITECAPS.
FORCE 4 11 - 16 KNOTS WAVE HEIGHT 1 - 1.5 M (3.5 - 5 FT.); SMALL WAVES BECOMING LONGER, NUMEROUS WHITECAPS.
FORCE 5 17 - 21 KNOTS WAVE HEIGHT 2 - 2.5 M (6 - 8 FT.); MODERATE WAVES, TAKING LONGER FORM, MANY WHITECAPS, SOME SPRAY.
FORCE 6 22 - 27 KNOTS WAVE HEIGHT 3 - 4 M (9.5 - 13 FT.); LARGER WAVES FORMING, WHITECAPS EVERYWHERE, MORE SPRAY.
FORCE 7 28 - 33 KNOTS WAVE HEIGHT 4 - 5.5 M (13.5 - 19 FT.); SEA HEAPS UP, WHITE FORM FROM BREAKING WAVES BEGINS TO BE BLOWN IN STREAKS ALONG DIRECTION OF WIND.
FORCE 8 34 - 40 KNOTS WAVE HEIGHT 5.5 - 7.5 M (18 - 25 FT.); MODERATELY HIGH WAVES OF GREATER LENGTH, EDGES OF CRESTS BEGIN TO BREAK INTO SPINDRIFT, FOAM IS BLOWN IN WELL MARKED STREAKS.
FORCE 9 41 - 47 KNOTS WAVE HEIGHT 7 - 10 M (23 - 32 FT.); HIGH WAVES, SEA BEGINS TO ROLL, DENSE STREAKS OF FOAM ALONG WIND DIRECTION, SPRAY MAY REDUCE VISIBILITY.
FORCE 10 48 - 55 KNOTS WAVE HEIGHT 9 - 12.5 M (29 - 41 FT.); VERY HIGH WAVES WITH OVERHANGING CRESTS, SEA TAKES WHITE APPEARANCE AS FOAM IS BLOWN IN VERY DENSE STREAKS, ROLLING IS HEAVY AND SHOCKLIKE, VISIBILITY IS REDUCED.
FORCE 11 56 - 63 KNOTS WAVE HEIGHT 11.5 - 16 M (37 - 52 FT.); EXCEPTIONALLY HIGH WAVES, SEA COVERED WITH WHITE FOAM PATCHES, VISIBILITY IS STILL MORE REDUCED.
