We've had this descussion before. I believe it's measured from trough to peak.
Look at time between waves (frequency) on the data chart.

It is measured Trough to peak. The bouy falls and rises and they measure the preasure change inside the bell. (at leaste that is how they used to do it.) 22 feet aint nothing for size however with the shallow water down there it can be devastating. We see wave heights like that all the time but we have deep water so it is not the same effect. In the "Perfect Storm" they were recording over 150 footers off the Grand Banks. Wicked stuff in that storm.
