Lake Wind and Wave Forecasts

Welcome to the Lake Wind and Wave Forecast page for Lake Sakakawea and Lake Oahe! Click on the images below to be directed to the forecasts for each lake. Since Lake Sakakawea and Lake Oahe have a large areal extent, Lake Sakakawea was divided into west, central, and east, and Lake Oahe into north and south. The text version of these forecasts is below.

Wind and wave forecast graphics are created twice daily, once in the early morning and again in the early evening. The forecasts are depicted as a series of images every three hours over a two day period.  Images show significant wave heights in feet and 10-meter winds above the ground in knots. 

These forecasts are created using the wind-wave model from the Great Lakes Environmental Laboratory (GLERL). Several other NWS offices also utilize this model for the Great Lakes and Lake Champlain. NWS Grand Forks also produces wave forecasts for Devils Lake in eastern North Dakota.

These are experimental forecasts as there is no bouy data available on either lake to verify forecast wave heights. We welcome your comments and reports about these experimental wave forecasts. Please send all comments and reports to w-bis.webmaster@noaa.gov.

*** Disclaimer: Models used to produce wave forecasts do not account for locally strong winds produced by thunderstorms. Wave heights can increase rapidly in and near thunderstorms. The best place to be during a storm is on shore in a reinforced shelter.***
