Weather in December

December is the beginning of the cold winter season in Maryland with gloomy skies, icy rain, and ample snow. The average high temperatures are in the cold 39°F (3.9°C) to 50°F (10°C), while the average low temperatures lie in the freezing 21°F (-6.1°C) to 33°F (0.6°C) zone. The Atlantic Ocean moderates the eastern shore, while downslope winds keep temperatures warm by 10°F (-12.2°C) on the eastern side of the mountains.
Western Maryland receives the heaviest snowfall in the state in the range of 5" (127mm) to 10" (254mm) barring the mountains which register above 15" (381mm). The precipitation is to the tune of 3" (76mm) to 5" (127mm) and occasionally mixes with the ice. Slush and icy roads are a dangerous driving combination along with low visibility in the winter.
Cascade Falls and Muddy Creek Falls, like many of their kind, offer breathtaking views with frost fingers and icicles hanging from the steep rocks. Wear warm winter coats in December in Maryland to protect from the numbing cold.
