December weather forecast

Snow becomes a more consistent feature, particularly in the northern and western uplands where accumulation can reach significant levels. The snow cover remains longer, often laying the groundwork for winter recreational activities. Lake-effect snow is common near Lake Superior and, to a lesser extent, Lake Michigan, affecting cities like Superior and Milwaukee respectively. In December, blizzards are not uncommon, adding an extra layer of challenge to travel and daily life.

In terms of daylight, the month is one of the darkest of the year. The winter solstice occurs in December, making for the shortest day and longest night. Cloud cover is frequent, further limiting the already scarce sunlight. This contributes to a quieter, more introspective atmosphere.

Although outdoor activities like hiking and biking are largely off the table, December is the kickoff for winter sports. Skiing, snowboarding, and ice fishing gain prominence as residents and tourists adapt to the winter conditions. Snowmobile trails begin to open, weather permitting, offering another avenue for winter enjoyment.

Agricultural activities are at a minimum during this month. Farmers focus on maintenance and planning for the next growing season, while also tending to livestock in indoor settings. December in Wisconsin is a time of holiday celebrations, winter sports, and preparation for the even colder months that January and February will bring.
