Is that "14+" the average height?
it's something called the Significant Wave Height. as a rule of thumb it's the mean wave height (peak to trough) of the highest 1/3rd of the waves.
Cheers, knew I'd read something about that before. From your link, and the red blobs (>10m waves) on the map posted by wwaswas above:
1 in 10 will be larger than 10.7 metres (35 ft)
1 in 100 will be larger than 15.1 metres (50 ft)
1 in 1000 will be larger than 18.6 metres (61 ft)
