Wisconsin is a four-season Midwestern state celebrated for its dairy heritage, vibrant craft beer scene, and remarkable natural beauty spanning two Great Lakes shorelines, thousands of inland lakes, ancient glacial landscapes, and dense north-woods forests. Milwaukee anchors the south with world-class museums, a famous Harley-Davidson legacy, and a dynamic food scene, while state capital Madison blends Big Ten university energy with progressive culture and farm-to-table dining. Door County's limestone bluffs and cherry orchards draw visitors north, and Wisconsin Dells delivers the nation's greatest concentration of water parks. Green Bay is home to the storied Packers NFL franchise and passionate cheeseheads who travel the state's back roads in search of supper clubs, Friday fish fries, and local craft breweries.
Wisconsin has a humid continental climate with four distinct seasons. Summers are warm and humid (June–August, highs 75–85°F/24–29°C), perfect for outdoor recreation. Falls are spectacular with brilliant foliage from late September through mid-October. Winters are cold and snowy (December–February, averages 15–30°F/-9 to -1°C; north Wisconsin regularly sees -20°F/-29°C). Spring arrives gradually in March–May with unpredictable weather. The northern third of the state (Northwoods) runs 5–10°F cooler year-round than southern Wisconsin.
