January weather forecast
Connecticut, USA

January is typically the coldest month in Connecticut, characterized by freezing temperatures and significant snowfall, especially in the northern hilly regions. During this month, average low temperatures range from 1°F (-17.2°C) to 3°F (-16.1°C), making it considerably colder compared to the preceding December and subsequent February. The coastal regions may experience milder weather, owing to their proximity to the water bodies.

The variation in snowfall across the state is noteworthy, with the south and east averaging 20" (508mm) annually, while the northern regions can receive up to 60" (1524mm). In higher elevations, snowfall can reach even greater depths, exceeding 150" (3810mm) in an unusually cold winter.

January is also a month when cold fronts from the Canadian North frequently invade the state. These conditions often lead to roads becoming slippery and black ice forming, making travel more challenging. Heavy fog is a common occurrence in coastal regions during late winter, further complicating visibility and travel.

There are no particular cities within Connecticut that stand out in terms of climate or weather during January, as the conditions are fairly consistent across the state. However, the varying topography may result in localized differences in snowfall and temperature, especially between the coastal areas and the inland northern regions.
