Weather in December

December brings the cold winter season to Utah, with a significant amount of snowfall. The average high temperatures are in the mild 30°F (-1.1°C) to 53°F (11.7°C) zone, and the average low temperatures are in the frigid 10°F (-12.2°C) to 30°F (-1.1°C) range. Richfield in the west is between an icy 16°F (-8.9°C) to mild 41°F (5°C), while Provo in the north-central region registers temperatures between a cold 24°F (-4.4°C) to mild 40°F (4.4°C).
Rain is scarce, but snowfall ranges from 5" (127mm) in much of the state to 15" (381mm) in the north. The mountains in the north and east restrict the entry of arctic air to no small degree. Cold air masses occasionally escape through the mountain passes and descend in the lowlands. Extremely cold temperatures are a regular occurrence in the cold desert lands.
Winter is the time of powdery snow that attracts snow lovers from all over the country. Skiing, snowshoeing, and snowmobiling are popular activities in the mountains. December is generally a month to avoid a visit to Utah.
