This is the ideal time for active leisure, when the days are warm but not exhaustingly hot.

Precipitation falls quite regularly throughout the year. Even in the warmest summer months, the number of rainy days remains consistent (about 12 days per month), so travellers are advised to carry an umbrella or raincoat regardless of the season. Spring and autumn serve as smooth transitional periods when the weather can be changeable, gradually preparing the city for winter chills or summer warmth.

The climate in Wausau is characterised by distinct seasonality with a significant difference between winter and summer figures. The winter period here is truly severe: the coldest months are January and February, when the average temperature holds at the level of -7°C...-7.6°C. Nights during this time are frosty, with the thermometer often dropping to -11°C...-12°C, and sub-zero temperatures prevail from December to March, requiring travellers to have warm winter gear.

Summer, on the other hand, brings pleasant and mild warmth to the region, avoiding extreme heat. The warmest month of the year is traditionally July, with an average temperature of about 21.4°C. During the day, the air usually warms up to a comfortable 26°C, creating excellent conditions for tourism, while August remains almost as warm, with average highs around 24.8°C.

It is worth noting the noticeable daily temperature fluctuations characteristic of this region, especially in the warm season. In summer, the difference between the daily maximum and nightly minimum is about 10 degrees: after a warm day when the temperature reaches 26°C, it can drop to a crisp 16°C at night. Such shifts ensure cool and comfortable evenings but suggest the need to carry light outerwear even at the height of summer.

In Wausau, the nature of precipitation depends directly on the time of year and temperature regime. Since the thermometer consistently drops below freezing in winter, precipitation from December to February falls mainly as snow. January can be called the "driest" month of the year in terms of precipitation volume, with snowy days occurring on average about 7 times a month.

The summer period brings not only warming but also increased humidity. June, July, and August are the rainiest months: precipitation falls most frequently during this time, roughly 12 days per month. Summer rains are a common occurrence here, so travellers planning a trip in the middle of the year are advised to keep an umbrella or raincoat with them.

In autumn, the frequency of precipitation begins to gradually decrease. While about 11 rainy days are still observed in October, by November their number drops to eight, and rain begins to give way to wet snow as winter approaches. Overall, the city does not have a pronounced dry season, though the wettest period is definitely summer.

Winter in Wausau requires serious preparation: temperatures often drop significantly below freezing, reaching lows of around -12°C in January and February. Be sure to bring high-quality thermal underwear, a warm down jacket, a hat, a scarf, and gloves. Since precipitation is possible even in the cold months, waterproof and insulated shoes with non-slip soles will be your best friend during walks.

Summer here is comfortable and warm, with average highs around +26°C, so t-shirts, shorts, and light trousers are suitable for daytime walks. However, considering the statistics on rainy days (up to 12 days a month in summer), do not forget to pack a compact umbrella or a light raincoat in your suitcase. Sunglasses and sunscreen will also come in handy, especially if you plan to spend a lot of time outdoors.

For a trip during the off-season (spring and autumn), the best strategy is the principle of layering. The weather can be changeable: from cool morning hours to warm afternoons. It is recommended to bring a fleece jacket, a windbreaker, or a cardigan that can be easily removed or put on as needed. Comfortable walking shoes are mandatory at any time of the year so that you can explore the city with comfort.
