Weather in January

January is usually the coldest month of the year in Wyoming, with the average low temperatures even below 0°F (-17.8°C) in the northwest regions - low temperatures go well below the average in many places. Central and southwest Wyoming is in the frigid 1°F (-17.2°C) to 32°F (0°C) average range with short days as the daily sunshine lasts for an average of 4 to 5 hours. The eastern and southern parts of the state are generally warmer than the rest: Buffalo averages between 14°F (-10°C) to 36°F (2.2°C), while Cheyenne, the capital of Wyoming, is in the cold range of 18°F (-7.8°C) to 40°F (4.4°C).
Winds are regularly in the 30 to 40mph (64.4km/h) range, while many a time the gusts blow with speeds in the 50 to 60mph (96.6km/h) range - strong winds from the west and southwest directions force trees to lean towards east or southeast in many localities. Chinook winds help to resist the drop in temperatures and corresponding snow accumulation.
Beware, January is the snowiest month of the year, particularly in the higher ranges of the mountains where it can easily cross 50" (1270mm).
