The Definitive Green Bay & the Fox Cities Weather Portal
Every forecast across Green Bay & the Fox Cities, highway-clear.
Official National Weather Service forecasts for Green Bay and the Fox Valley — nine counties up the Fox River and around the bay, from Oshkosh and Appleton through De Pere and Green Bay to Oconto, Marinette and the Michigan line.
Every Wisconsin region shares one system — the same maps, the same live radar, the same climate record. The bay freezes and the lake does not, and the difference shows up in the forecast all winter. Cold air crossing open Lake Michigan piles snow on the counties east of the Fox, Lambeau sits in the lake-effect shadow more often than people think, and the spring ice-out on Winnebago is its own local season.
