January is usually the coldest month of the year in Alabama with wet days and occasional freezing nights. The precipitation is to the tune of 4.5" (114mm) to 6" (152mm), with the northern part slightly wetter than the coast and significantly more than the central portion. The average low temperatures are between 28°F (-2.2°C) in the north to 46°F (7.8°C) along the Gulf Coast. Montgomery, the capital in the south, registers in the cold 36°F (2.2°C) to mild 57°F (13.9°C) range. Severe cold seldom occurs due to the interaction of dry, cold continental air with the moist and warm air from the Gulf. However, the average low temperatures are cold at the peak of the winter. The Tennessee River Valley occasionally registers temperatures below 0°F (-17.8°C), while they are rare and brief in the south. A winter jacket protects from wind chill and sudden rainfall. Alabama is one of the few states with considerable tourist footfall in January due to the warm conditions compared to the rest of the United States.
