Subject... wave terminology in marine coastal waters forecasts
... Effective June 1 2015

Beginning June 1, 2015, the National Weather Service in Portland
Oregon will begin adding wave direction and period to the wind wave
terminology in the coastal waters forecast.

Also, when the swell and wind wave components cannot be clearly
distinguished, we will characterize the sea state as mostly wind
waves with little to no swell. In these situations, we will be use
wave terminology such as wind waves, NW at 6 ft and 8 seconds, NW
swell less than 1 ft in the coastal waters forecast.

When the wind wave and swell wave components can be distinguished,
we will continue to use existing swell and wind wave terminology
such as NW swell 10 ft at 8 seconds, wind waves, NW at 4 ft and 9
seconds.

Questions concerning this change should be directed to:
