December in Big Bear establishes the rhythm for the entire winter season, setting a crisp and clear tone that defines the mountain experience. This month marks the heart of the ski and snowboard season, drawing visitors who seek both high-energy adventure and peaceful alpine escapes. While heavy snowfall is common, the region also enjoys crisp, sunny days that provide stunning visibility across the lake and surrounding peaks. Understanding the specific conditions of Big Bear weather in December helps travelers pack appropriately and plan activities with confidence.
Temperature and General Conditions
Average daytime highs in Big Bear during December typically hover between 40 and 50 degrees Fahrenheit, while nighttime temperatures often drop into the low 20s or even high teens. Snowfall is a near certainty, with the monthly average accumulation generally ranging from 8 to 14 inches, although individual storms can deliver significantly more. Lake-effect influences from the large surface area of Big Bear Lake frequently generate moderate snowfall that can persist for hours, creating dramatic whiteout conditions at times. Clear, cold snaps between storm systems produce sparkling snow and excellent visibility, making it ideal for photography and scenic drives.
Ski and Snowboard Season Peak
For skiers and snowboarders, December is arguably the most reliable month to visit Big Bear Mountain resorts. Natural snowfall combines with efficient snowmaking systems to ensure extensive terrain coverage and well-groomed slopes. Beginners appreciate the consistent conditions and manageable crowds compared to holiday weeks, while intermediate riders find plentiful cruising areas and gentle progression zones. Advanced skiers benefit from the higher elevations and varied tree runs that often remain open even during widespread storms. Families frequently choose this period for reliable powder days and discounted multi-day lift ticket packages.
Holiday Atmosphere and Local Events
The festive season transforms Big Bear with decorated streets, illuminated lodges, and a lively yet manageable holiday spirit. Many resorts host special events such as night skiing, holiday cookie decorating, and après-ski gatherings that emphasize community warmth. Local shops focus on winter-ready gear and souvenirs, while restaurants highlight hearty, warming dishes that reflect mountain traditions. Visitors should anticipate increased occupancy and higher demand for lodging, making early reservations essential for a smooth holiday experience. Balancing holiday cheer with off-peak travel days can yield a more relaxed and personal connection to the town’s charm.
Wildlife and Winter Ecosystem Activity Although less visible than in warmer months, the Big Bear ecosystem remains active throughout December. Black bears entering dens reduce encounters on trails, while deer and smaller mammals adapt their routines to conserve energy amid frequent storms. Birdwatchers may spot hardy species such as nuthatches, chickadees, and occasionally golden eagles riding thermals above the clouds. The quiet of a freshly snowed landscape reveals subtle details like animal tracks crossing open meadows and pine branches weighted with pristine snow layers. Respecting wildlife corridors and maintaining distance ensures minimal disturbance during this sensitive season. Preparation and Packing Recommendations

Successful visits to Big Bear in December begin with thorough preparation focused on warmth, mobility, and safety. Layered clothing systems that combine moisture-wicking base layers, insulating mid-layers, and waterproof outer shells perform best in changing conditions. Waterproof boots with aggressive traction are essential for navigating icy sidewalks and packed snow trails, while gloves, hats, and thermal socks prevent heat loss during extended outdoor sessions. Travelers should also include backup clothing, high-energy snacks, and a basic first-aid kit, particularly when venturing onto less-traveled backcountry roads or hiking paths.
Driving and Access Considerations
Road conditions in and around Big Bear demand attention during December, as snow and ice can create hazardous stretches on mountain passes and secondary roads. All-season tires are common but may be insufficient during heavy storms; vehicles equipped with snow tires or chains often experience significantly improved traction and control. Real-time updates from local transportation authorities help drivers choose optimal routes and avoid temporary closures due to avalanche control or accident response. Maintaining extra travel time and flexible schedules reduces stress and allows for safe navigation through picturesque yet challenging winter scenery.
