September is one of the best times to visit Wisconsin with beautiful weather conditions. The average high temperatures hover in the 60°F (15.6°C) to 74°F (23.3°C) range, while the average low temperatures are in the warm 55°F (12.8°C) to 65°F (18.3°C) range. Peak summer temperatures hold no more in September, but the days are long and bright with a drop in the amount of rain. Though cloudy days are in fair numbers, the overall weather gives a feeling of pleasantness as the autumn spreads its wings. Leaves start to turn color by mid-September, and the northern lands attain brilliant shades of orange, amber, yellow, red, and golden by the end of the month. The bright conditions are perfect for hunting, fishing, and exploring the wilderness. Even in the peak tourist season, Wisconsin has plenty of space for everyone, and the fall feels much more spacious with the dispersal of the summer crowds. Keep an eye on the weather, as tornadoes are common in September!
