What's the Typical December Snowfall in Big Bear?

December in Big Bear is usually a magical time, especially if you're dreaming of a white Christmas. On average, Big Bear Lake sees a good amount of snowfall during this month, making it a popular destination for winter sports enthusiasts. Generally, you can expect anywhere from 20 to 40 inches of snow throughout December. However, keep in mind that this is just an average. Some years might bring heavier snowfalls, while others could be a bit drier. This variability is what makes checking the forecast so crucial before you pack your bags.

Now, let’s break that down a bit more. Early December often sees the first significant snowfalls of the season, building up the base for skiing and snowboarding. Mid-December usually maintains consistent snow cover, perfect for holiday adventures. Late December can sometimes bring the biggest storms, setting the stage for a snowy New Year. The key is to stay updated with the local weather forecasts as your trip approaches.

For those planning to hit the slopes, the two main ski resorts, Bear Mountain and Snow Summit, rely heavily on this natural snowfall, supplemented by snowmaking. The resorts typically aim to open in late November or early December, depending on the early season snow. By December, most runs are usually open, offering a fantastic variety of terrain for all skill levels. Whether you're a beginner or an expert, you'll find something to enjoy.

Beyond the ski resorts, the town of Big Bear Lake itself transforms into a winter wonderland. The snow-covered trees, cozy cabins, and festive decorations create a charming atmosphere. Imagine strolling through the village with a cup of hot cocoa, surrounded by snow-capped mountains – it's truly a postcard-perfect scene. Just remember to pack your warm boots and layers of clothing to stay comfortable while exploring.

Moreover, the consistent snowfall in December significantly boosts the local economy. Hotels, restaurants, and local businesses thrive during this peak season, providing numerous jobs and services for visitors. The community takes pride in maintaining the roads and facilities to ensure everyone has a safe and enjoyable experience. So, when you visit Big Bear in December, you're not just enjoying a vacation; you're also supporting a vibrant local economy.

Factors Influencing the Snow Forecast

Alright, let's get a bit nerdy and talk about the factors that influence Big Bear's snow forecast. Understanding these elements can help you make more informed decisions about your trip. Several key atmospheric conditions and geographical aspects play a role in determining how much snow Big Bear receives each December.

First off, the Pacific Ocean is a major player. Storms that develop over the Pacific are the primary source of moisture for Southern California, including Big Bear. The strength and track of these storms can vary greatly, impacting the amount of precipitation that reaches the mountains. Meteorologists closely monitor these systems to predict potential snowfall.

Another crucial factor is the elevation. Big Bear Lake sits at an elevation of around 6,750 feet, and the surrounding mountains rise even higher. Higher elevations generally experience colder temperatures, which are essential for snow formation. As moist air rises over the mountains, it cools and condenses, leading to snowfall. This orographic lift is a significant reason why Big Bear gets more snow than the lower-lying areas of Southern California.

The jet stream also plays a vital role. The jet stream is a high-altitude wind current that steers weather systems across the globe. When the jet stream dips southward, it can bring colder air and more frequent storms to California. Conversely, a more northerly jet stream can result in drier conditions. Predicting the position and strength of the jet stream is a key component of long-range weather forecasting.

El Niño and La Niña are also important climate patterns to consider. These are periodic variations in sea surface temperatures in the equatorial Pacific Ocean that can influence weather patterns worldwide. El Niño years tend to be warmer and drier in Southern California, while La Niña years often bring cooler and wetter conditions. Understanding which phase we're in can provide some insight into the potential for snowfall.

Local geographical features also contribute to the microclimate of Big Bear. The surrounding mountains can create localized weather patterns, such as wind shadows and enhanced precipitation zones. These small-scale variations can be challenging to predict but can significantly impact the amount of snow that falls in specific areas.

Finally, climate change is an increasingly important factor to consider. While natural variability has always influenced snowfall patterns, the long-term effects of climate change are becoming more evident. Warmer temperatures can lead to more precipitation falling as rain instead of snow, and can also reduce the overall snowpack. Monitoring these trends is crucial for understanding the future of winter sports in Big Bear.

How to Read a Snow Forecast

Okay, so you're checking the snow forecast – great! But how do you actually read and interpret it? It's not just about seeing a number and assuming that's exactly what you'll get. Let's break down the key elements of a snow forecast and how to make sense of them.

First, pay attention to the date and time of the forecast. Weather conditions can change rapidly, especially in the mountains. A forecast that's more than a few days old might not be very accurate. Look for forecasts that are updated frequently, ideally within the last 24 hours.

Next, check the snowfall predictions. Most forecasts will give you an estimate of how much snow is expected to fall over a specific period, usually in inches. Keep in mind that this is just an estimate, and the actual amount could be higher or lower. Look for forecasts that provide a range of possible outcomes, rather than just a single number.

Pay attention to the timing of the snowfall. A forecast might predict several inches of snow, but if it's spread out over several days, the impact might not be as significant. Look for forecasts that indicate when the heaviest snowfall is expected to occur. This can help you plan your activities accordingly.

Temperature is another crucial factor to consider. Snow is more likely to accumulate when temperatures are at or below freezing (32°F or 0°C). If the forecast calls for temperatures above freezing, the snow might melt quickly, especially at lower elevations. Also, be aware of the possibility of rain or mixed precipitation, which can make conditions icy and unpleasant.

Wind speed and direction can also affect snowfall. High winds can blow snow around, creating drifts and reducing visibility. If the forecast calls for strong winds, be prepared for challenging conditions on the slopes. Also, be aware of the potential for road closures due to blowing snow.

Look for forecasts that provide information about snow level. This is the elevation at which snow is expected to fall. If the snow level is higher than the elevation of Big Bear Lake, you might not see any snow in town, even if the mountains are getting a good amount. This is especially important if you're planning to drive to Big Bear, as the roads at higher elevations could be snow-covered.

Finally, consider the source of the forecast. Different weather models and forecasting agencies might produce slightly different results. It's a good idea to consult multiple sources to get a more complete picture of the expected weather conditions. Local weather websites and news channels are often the most accurate, as they have specific knowledge of the area.

Waterproof boots are a must, especially if you plan to spend time in the snow. Don't forget sunscreen and sunglasses, as the sun can be intense at high elevations, even on cloudy days.

Check Road Conditions: Before you head up to Big Bear, check the road conditions. Mountain roads can be treacherous in the winter, especially after a snowfall. Caltrans provides updated information on road closures and chain requirements. Make sure your vehicle is properly equipped for winter driving, and consider carrying chains, even if they're not required.

Plan Activities Based on the Weather: Be flexible with your plans and adjust your activities based on the weather. If it's snowing heavily, consider spending the day skiing or snowboarding. If the weather is clear and sunny, go for a hike or explore the town. Have a backup plan in case your original activity is not possible due to weather conditions.

Rent or Bring Winter Gear: If you plan to ski or snowboard, you'll need to rent or bring your own gear. Big Bear has several rental shops that offer a wide range of equipment. If you're not sure what you need, the staff can help you choose the right gear for your skill level.

Stay Hydrated: It's easy to get dehydrated in the winter, especially at high elevations. Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid excessive alcohol consumption, as it can worsen dehydration.

Be Aware of Altitude Sickness: Big Bear Lake is located at a high elevation, so it's possible to experience altitude sickness. Symptoms can include headache, nausea, and fatigue. To prevent altitude sickness, take it easy on your first day, avoid strenuous activities, and drink plenty of water. If you experience severe symptoms, seek medical attention.
