January is usually the coldest month of the year in North Dakota, with the average low temperatures in the icy -4°F (-20°C) to 6°F (-14.4°C) range. Bottineau and Rugby in the central region witness frigid temperatures in the -4°F (-20°C) to 17°F (-8.3°C) zone. January is the snowiest month with 9" (229mm) to 12" (305mm) of snow in the majority of the state. The strong northern winds face scarce resistance on the vast prairie. Parkas and boots are mandatory with the increase in the snow depth and snow cover. Despite its location on the northern boundary of the United States, the average snow depth rarely goes above 15" (381mm). Dense fog is prevalent during the mornings in many places, and the daily sunshine rarely lasts for 5 hours. Frost, sleet, and ice make driving dangerous even during the day when the sunlight is weak at best. Occasional blizzards stall the highways, so keep an eye on the weather if the objective is to visit North Dakota for enjoying the snow in January.
