Using the numerical wave model SWAN, 42 hour predictions of the wave conditions using NAM wind-fields (courtesy NCEP) for Bristol Bay are made once a day.

Hs links provide plots of  Significant Wave Heights (m) along with plots of  input Wind Directions (scaled by the input Wind Speed).

Tp links provide plots of Peak Wave Periods (sec) along with plots of Peak Wave Directions (scaled by the Significant Wave Height). 

Sd links provide plots of Stokes drift Directions (scaled by the drift velocity). 

Predicted wave conditions can be viewed by clicking on the corresponding link in the table below.
