Weather in January

January is the coldest month of the year in Colorado, with the temperatures even below 0°F (-17.8°C) in many parts of the west. The average low temperatures are between -8°F (-22.2°C) to 22°F (-5.6°C), while the average high temperatures are in the 25°F (-3.9°C) to 49°F (9.4°C) range. Denver, the capital in eastern Colorado, averages between 17°F (-8.3°C) to 45°F (7.2°C), while Alamosa in western Colorado is cold and averages between -2°F (-18.9°C) to 34°F (1.1°C).
Snowfall is heavy in the west, and places such as Steamboat Springs and Crested Butte register approximately 40" (1016mm). Days are short with fading sunlight, and nights are severely cold. January is mostly dry, and rainfall scarcely registers above 1" (25mm) statewide.
Chinook winds help Front Range cities to maintain relatively warm conditions. Microclimates exist in Colorado that range from alpine to cold desert type, and conditions may be radically different in the space of a few miles.
Skiers and snowboarders find the thick snow fascinating in the Colorado Mountains. New Year attracts a few tourists, but overall, January is an off-season for tourism.
