WebIn December the K3 buoy measured a significant wave height of 18.2 m and in March K2 measured a wave height of 17.6 m - the two highest wave events ever recorded by the network. The maximum wave heights (crest to trough) were probably several times higher than the significant wave height. WebIn a wave spectrum with a significant wave height of 47 feet, the highest 10% of waves (H1/10) would equal 1.27 x 47 = 60 ft. And the theoretical maximum wave height in that spectrum is 94 feet (2 times Hs)!! Prudent mariners know the physical limits of their vessels with respect to wind speed and wave height.
