About these Forecasts

This forecast is available during the boating season, usually April through the end of October. The forecast, both graphical and text, is generated several times per day with updates made when weather conditions become unrepresentative. Use with caution. Be sure to check the product creation time to verify that the forecast you are viewing is current. Forecasts are valid for either 36 or 48 hours dependent on issuance time. Forecast elements include winds, significant wave heights, sensible weather, and associated restrictions to visibility if applicable over the open lake waters.

A wave model is run by NWS in Green Bay which produces the wave height forecast for Lake Winnebago. Forecasters at NWS Green Bay develop the wind forecast that is used in the wave model. The wave model has been used on the Great Lakes and has been shown to do reasonably well.

The latest observations for sites along the lake are also being provided. You may ask “Are these really the kind of winds you can expect on the open area of a lake or reservoir?” Any lake recreationalist will probably tell you that the winds are often found to be stronger than what was forecast or seen at the surrounding observation sites. Studies have shown that there is approximately a 4 to 5 mph increase in sustained wind speeds on open bodies of water compared to the nearest airport. Keep in mind that this difference is over an open waterway and is not necessarily what one would find if they were boating in a protected pocket of the waterway or near a wind protected structure such as a tree line, an island or point.
