Sheboygan Weather: Warm Midweek, Cooler Weekend, Showers Returning by Sunday

Right now in Sheboygan, it’s a sunny and warm 82°F this Wednesday afternoon (September 17, 2025). The National Weather Service radar out of Milwaukee/Sullivan shows clear skies across much of eastern Wisconsin, giving us a stretch of late-summer weather that feels more like July than mid-September.

Midweek Outlook: Sunshine and Comfortable Breezes

This afternoon will stay bright with highs near 80°F and light south winds. Tonight dips to around 61°F under partly cloudy skies. Thursday brings a shift, with cooler north winds keeping the high closer to 72°F. By Thursday night, temperatures fall into the upper 50s under partly cloudy skies.

Friday stays on the cooler side, topping out near 69°F, with light northeast breezes and lots of sunshine. Friday night will be mild with lows in the upper 50s.

Weekend Weather: Clouds Build, Showers Possible

Saturday continues the pleasant streak with highs around 69°F, though clouds increase by evening. A slight chance of rain showers enters the picture Saturday night as temps hold near 59°F.

Sunday warms up to 74°F but brings the first real chance of unsettled weather in a while. Expect scattered showers and thunderstorms through the day and into the evening.

Early Next Week: Warm with Storm Chances

Monday looks a lot like Sunday—partly sunny, warm at 76°F, but with scattered showers and thunderstorms. Rain chances linger into Monday night and Tuesday morning before skies clear. Highs Tuesday reach the mid-70s before dipping into the 50s overnight.

What This Means for Sheboygan

This week offers a little bit of everything—plenty of sun for outdoor plans midweek, comfortable temps for weekend activities, and the chance for rain to water late-summer gardens by Sunday. If you’re planning a fall hike, beach walk, or evening out, Thursday and Friday look especially nice. Keep an umbrella handy for Sunday through Tuesday.
