January is the coldest month of the year in Montana as the temperatures are in the frigid zones. The average low temperatures in the eastern half dive to 2°F (-16.7°C) in Glasgow, while they are around 22°F (-5.6°C) in Flathead Lake in western Montana. Average high temperatures are in the 22°F (-5.6°C) to 32°F (0°C) zone as the days are short and cold in the absence of strong sun. January is also the snowiest month of the year that receives one-third of the average annual snowfall across the state. The southwestern mountain ranges receive a vast amount of snow to the tune of 40" (1016mm), while high elevation plateaus like Cooke City in the south accumulate 35" (889mm). January is a slow tourist season but sees winter enthusiasts for activities like dog sledding, sleigh riding, snowshoeing, and ice fishing, among others. Expect a deep snowpack in the mountains up to 100" (2540mm) and the sunshine to last only for 4 hours a day amid cloudy skies in the west and mostly clear skies in the east.
