Re: Determining storm distance by wave freq. or ampl.

Here in Hawaii, if a wave train has periods in the teens of seconds say 13-17 seconds, those waves are generated by storms at least 2-3,000 miles away. Short period waves under 10 seconds are generated by winds within say 800 miles.

the long period waves (13-17 seconds) can have wave heights up to 30 feet or more. That will lead to a breaking wave face of 60 feet or more. The longer the wave period the more energy for equivilent height ocean swell.
