Background reading: Green Lake on Wikipedia
Set in Green Lake County, Wisconsin, Green Lake is a 7,651-acre natural lake.
We read the level from USGS gauge 434840089000001, listed as Green Lake at Green Lake, WI. Wind and weather come from the National Weather Service grid cell over the lake, so the numbers describe open water rather than the nearest airport.
It is big enough for a proper sail but small enough that waves rarely get serious. Gusts off the shoreline are usually the bigger story than wave height.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
