I always enjoyed the discrepancy between sizing ocean waves and sizing river
waves. Ocean waves are assumed (fairly correctly) to be centered on the
local sea level, with a trough in front and a peak between the troughs. In a
4-foot ocean wave, there is a 4 foot deep trough in front, and a 4 foot high
peak on the wave, leaving an 8 foot wave face.

This is not the way they're forecast by NOAA. A 4' sea is 4' from trough to
peak. Either that, or their forecasts are wildly inflated.
