Wind-Wave Forecasts

Wind-Wave Forecasts
for
Devils Lake (ND), Red Lakes (MN), and Lake of the Woods (MN)


The National Weather Service Office in Grand Forks North Dakota invites you to visit the “Lake Wind-Wave Forecast” web page for the three major lakes in our forecast area; Devils Lake, Upper and Lower Red Lakes, and Lake of the Woods.

The forecasts are given as a series of maps for each 3 hours covering the next 2 days. The forecast shows the significant wave heights* over the lakes and the 10-meter winds the model uses to generate them.

The wind-wave forecast will be updated when the weather forecast is updated, at least every 3 hours. Weather and wave grid resolution is set to 2.5 km grid boxes.

The wind-wave model is from the Great Lakes Environmental Research Laboratory (GLERL) and is currently used by NWS forecast offices for the Great Lakes, and selected inland lakes across the region.

To directly view the Lake Wind-Wave forecasts go to:
