Wyoming weather in December is a fascinating topic that offers a unique glimpse into the state’s winter landscape. With its cold and unpredictable climate, December in Wyoming is a time for residents and visitors to bundle up and enjoy the winter activities and festivals that the state has to offer.
The content of this article will delve into the various aspects of Wyoming’s weather in December, including the temperature fluctuations, snowfall, humidity levels, and the impact on the state’s economy and winter sports.
Wyoming’s average snowfall in December is significantly greater than in other parts of the country, with the highest amounts recorded in the mountainous regions.

Wyoming, known for its rugged terrain and harsh winters, experiences heavy snowfall in December, which affects transportation in various ways. As one would expect, the snow-covered roads pose significant challenges to drivers, especially in areas with limited infrastructure.
With heavy snowfall comes increased road maintenance requirements. The Wyoming Department of Transportation (WyDOT) works tirelessly to keep highways safe and passable. Crews are dispatched to clear snow from roads, salt to prevent icing, and repair damaged sections of pavement. This process requires careful planning and execution, often taking place around the clock.
Road Closures and Maintenance Requirements
Road closures are a harsh reality in Wyoming during December, especially in areas with steep grades and winding roads. The heavy snowfall can cause roads to become impassable, leaving travelers stranded. To mitigate this, WyDOT has implemented an array of strategies, including:
- Real-time road monitoring systems to track snowfall and road conditions.
- Emergency service corridors, which are cleared and maintained year-round, to allow emergency responders and snowplows to navigate through heavy snowfall areas.
- Winter driving restrictions, which advise drivers to stay off roads during extreme weather conditions.
- Public outreach campaigns to inform residents and visitors of road closures and maintenance schedules.
In Jackson, one of the snowiest towns in Wyoming, residents have grown accustomed to the challenges of December snowfall. However, it’s not uncommon for roads to become impassable, leaving locals and tourists stranded. One local resident recalled, “I was driving home from work one evening when the snow started coming down in sheets. I knew I had to get home, but the roads were getting increasingly slippery. I ended up pulling over and waiting until morning when the snowplows had cleared the road.”
For tourists, navigating Wyoming’s snow-covered roads can be a daunting task. Visitors often rely on GPS and local guidance to stay informed about road conditions. As one visitor noted, “I’m from California, so I’m not used to driving in snow. I was a bit nervous at first, but once I got acclimated to the conditions, I felt more confident.”
Average Snowfall Amounts in Wyoming Cities
Here is a table detailing the average snowfall amounts in various Wyoming cities, including Jackson, Cheyenne, and Casper:
| City | December Average Snowfall (in) | Maximum Recorded Snowfall (in) | Record Date |
|---|---|---|---|
| Jackson | 33.4 | 66.5 | December 17, 1992 |
| Cheyenne | 12.1 | 23.5 | January 10, 1993 |
| Casper | 5.1 | 17.5 | February 10, 1968 |
Extreme Snowfall Events
Wyoming has experienced some of the most extreme snowfall events in recent history. For example, in December 1992, a blizzard dumped 62 inches of snow in Jackson, causing widespread power outages and disrupting transportation. Another notable event occurred in 1993, when a nor’easter brought 24 inches of snow to Cheyenne, causing treacherous road conditions and stranding hundreds of travelers.
The Low Humidity Levels in Wyoming During December Can Be Challenging for People with Respiratory Issues.
Wyoming’s December weather brings a mix of cold temperatures and low humidity, which can be harsh on the human body, especially for those with pre-existing respiratory conditions like asthma. The low air humidity can cause the airways to dry out, making it more challenging to breathe. In this context, it’s essential to take proactive steps to protect oneself from the dry air and monitor the air quality closely.
People with respiratory issues should take note of the humidity levels in their area, as dry air can exacerbate symptoms. Using a humidifier can help add moisture back into the air, making it easier to breathe. Additionally, drinking plenty of water and staying hydrated can also help alleviate respiratory issues. Furthermore, avoiding irritants like cigarette smoke and strong chemicals can also help minimize the risks associated with low humidity.
Using Humidifiers and Staying Hydrated
Using a humidifier can be an effective way to combat dry air. There are different types of humidifiers available, including cool-mist and warm-mist models. Cool-mist humidifiers are ideal for people with allergies, as they don’t release hot water vapor that can exacerbate respiratory issues. Warm-mist humidifiers, on the other hand, are better suited for people with congestion, as the warm vapor can help loosen mucus.
Staying hydrated is also crucial during the winter months. Drinking plenty of water can help keep the airways hydrated and prevent congestion. Herbal teas, such as peppermint and echinacea, can also help soothe the throat and promote hydration. In addition, warm liquids like soup and hot chocolate can help moisturize the airways and provide a warm, comforting drink.
The Role of Humidity in Contributing to Frost and Freezing Temperatures.
Low humidity levels play a significant role in contributing to frost and freezing temperatures in Wyoming. When the air is dry, it can’t hold as much heat, making it more susceptible to cooling down rapidly. As the temperature drops, the dew point also decreases, leading to the formation of frost and ice.
Humidity levels below 30% can lead to the formation of frost, while humidity levels below 20% can lead to the formation of ice. In areas with low humidity, the air can cool down rapidly, leading to the formation of frost and freezing temperatures. This can be particularly challenging for people with respiratory issues, as the cold air can exacerbate symptoms.
Air Quality in Rural Versus Urban Areas.
Air quality in rural areas of Wyoming can be different from that in urban areas during December. Rural areas tend to have lower levels of air pollution, as there are fewer emissions from vehicles and industrial activities. However, air quality can still be affected by agricultural activities, such as farming and ranching.
Urban areas, on the other hand, tend to have higher levels of air pollution due to emissions from vehicles, industrial activities, and other human sources. In areas with high levels of air pollution, the air can be particularly challenging for people with respiratory issues. Using air purifiers and staying indoors can help minimize exposure to pollutants.
Differences in Pollution Levels and Health Risks.
The health risks associated with air quality in rural and urban areas can differ significantly. In rural areas, exposure to pollutants from agricultural activities can lead to respiratory issues, such as asthma and chronic obstructive pulmonary disease (COPD). In urban areas, exposure to pollutants from vehicles and industrial activities can lead to a range of health problems, including respiratory issues and cardiovascular disease.
It’s essential to monitor air quality closely, especially during December, when humidity levels are low and air pollution can be exacerbated. Staying informed about local air quality conditions can help minimize health risks and protect oneself from the harsh weather conditions.
Wyoming’s Perfect Winter Playground

Wyoming’s winter landscape is a haven for winter sports enthusiasts, offering a wide range of activities that bring excitement and adventure to the state. As the snowflakes start falling in December, the mountains, valleys, and lakes transform into a picturesque winter wonderland that invites you to lace up your skis, grab your ice fishing gear, or strap on your snowshoes.
In order to brave the cold and enjoy the winter sports, it is essential to be well-equipped with the right gear and clothing. When engaging in activities such as skiing and snowboarding, a good pair of warm, waterproof boots and waterproof socks that can keep your feet dry and toasty are crucial. Additionally, wearing several layers of breathable clothing will help prevent overheating and allow for better sweat management.
A waterproof and breathable jacket is a must-have for both wind and rain protection, along with a warm hat and gloves to prevent heat loss. A scarf or neck gaiter can help cover your face and prevent windburn. It’s also important to wear sunscreen and protective eyewear to shield your skin and eyes from the harsh winter sun.
Packing the Essentials for Wyoming’s Winter Sports
A well-stocked first aid kit is always a good idea when venturing into the wilderness. This should include essentials such as bandages, antiseptic wipes, pain relievers, and any personal medications. A fully charged phone and a portable charger can also come in handy in case of an emergency or when navigating through remote areas with no cell signal. It’s also a good idea to bring a map, compass, and GPS device or a smartphone with a GPS app to help navigate through unfamiliar terrain.
