December weather forecast
South Carolina, USA

December in South Carolina welcomes winter's onset, characterized by colder temperatures and occasional frosty mornings. Coastal regions, including areas like Myrtle Beach, witness temperatures fluctuating between 38°F (3.3°C) to 60°F (15.6°C). Days are moderately cool, but as darkness descends, the chill intensifies, hinting at the deeper cold of mid-winter.

The Midlands, where cities such as Columbia lie, experience the fresh chill of winter more acutely. The warmth of previous months becomes a nostalgic memory as residents navigate colder days and even frostier nights. The Upstate, nestled near the Blue Ridge Mountains, feels winter's touch most distinctly. This region, especially at higher elevations, sees the occasional snowfall, transforming the landscape into a serene white tableau, albeit briefly.

December is marked by sporadic rain showers, but they are typically light and infrequent. Snow is rare along the coast, but the interior and northwestern mountains might accumulate some, particularly as the month progresses. As one would expect in winter, humidity is at its lowest, resulting in clearer air and often brilliantly blue skies on days when clouds don't dominate.

In comparison to November, December's chill becomes more established, solidifying winter's grip on the state. The festive spirit of the holiday season provides a warm counterpoint to the cold outdoors. As December draws to a close, South Carolina awaits the depth of winter in the coming months, with January promising even colder conditions, particularly in the Upstate region.
