Weather in December

December heralds the onset of winter in Maryland, with temperatures typically ranging from 30°F (-1.1°C) to 50°F (10°C). The state experiences a substantial drop in temperature compared to November, and the landscape transitions into a winter wonderland, particularly in the western portions.

The coastal areas of Maryland continue to experience milder temperatures due to their proximity to the ocean, but even these regions are not immune to the cold. The humid subtropical climate gives way to more freezing conditions, while the western part of the state, influenced by a humid continental climate, prepares for snow and freezing temperatures.

Snowfall becomes a significant feature in Maryland's winter, particularly in the western highlands. The Allegheny Plateau and Appalachian Mountains can receive between 30" (762mm) and 40" (1016mm) of snow during the season. The town of Oakland is renowned for its heavy snowfall, often exceeding 100" (2540mm) annually.

Frost becomes a daily occurrence, and nights can often register below 0°F (-17.8°C), especially in the western regions where the Appalachian Mountains provide some barrier from arctic cold. Cold fronts, cyclones, and anticyclones contribute to rapid changes in weather, sometimes leading to blizzards and icy conditions.

Outdoor activities shift towards winter sports, such as skiing and snowboarding, particularly in the mountainous areas. The snow and cold create a festive atmosphere, aligning with the holiday season.

Compared to November's transitional weather, December firmly establishes the cold and snowy conditions that define Maryland's winter. The contrast with the mild and colorful autumn is stark, as the state embraces the chill, snow, and unique beauty of the winter season.
