From April to October, during the warmer time of year, precipitation falls as rain.

When planning a trip to Sturgeon Bay, it is important to consider the variable weather throughout the year and dress in layers. This will allow you to easily adapt to temperature fluctuations, especially during the transitional seasons. Regardless of the timing of your visit, comfortable walking shoes are a must-have, as you will likely be doing a lot of exploring. Given that on average 9-12 days per month may have precipitation (though light in volume), it is worth bringing a light umbrella or a compact waterproof jacket.

For a visit during the cold months, which in Sturgeon Bay last roughly from November to March (average temperatures from -4.4°C to 0.2°C, with lows reaching -7.6°C), you will need warm winter clothing. Pack an insulated and preferably windproof jacket, warm sweaters or fleeces, a hat, scarf, and gloves. Thermal underwear can also be very useful, especially on the frostiest days of January and February. Don't forget waterproof and warm footwear to comfortably navigate snow or slush.

During the warmer months, from May to September, when average temperatures range from 11°C to 21.6°C (July being the warmest month), your wardrobe should consist of light and breathable clothing. T-shirts, shorts, light trousers, skirts, and dresses will be very appropriate. However, even in summer, evenings can be cool, especially if you plan walks near the water, so bring a light sweater, cardigan, or windbreaker. In the summer months (June-August), be sure to use sunscreen, wear a hat, and sunglasses for UV protection.
