January is the coldest month of the year in Maine, as the daily high temperatures are regularly below freezing. Day high temperatures even in coastal areas like Portland average cold 31°F (-0.6°C), while the nightly lows are approximately 13°F (-10.6°C). The lake areas like Moosehead Lake and Chesuncook Lake in the north freeze during the winter with average low temperatures of -1°F (-18.3°C). Many parts of the state see temperatures below 0°F (-17.8°C) regularly as the sunshine reduces to an average of 4 hours a day, and the sun is visible only for 15 days during the month. January sees a drop in humidity to 70% as the rainfall averages 4" (102mm) in Maine; it is also the snowiest month with many places accumulating north of 20" (508mm), the lake areas, particularly gathering more snow. Few visitors step in Maine during the winter - the arctic cold mandates layers of winter clothing such as gloves, warm coats, caps, and shoes. Watch out for Moose crossings when driving automobiles as these animals casually walk across the roads!
