December in Seattle, Washington, is typically characterized by cool, wet, and often overcast conditions. The city experiences its highest rainfall during this month, and while significant snowfall is not as common as rain, it can occur. Residents and visitors alike should be prepared for a range of weather conditions when navigating Seattle in December.
Typical Weather Conditions in Seattle in December
Seattle weather in December generally involves a combination of cold temperatures, frequent rainfall, and limited sunshine. Understanding these typical conditions can help individuals prepare for the month and plan accordingly.
Temperature Range
The temperature in Seattle during December usually fluctuates within a narrow range. Daytime highs average around 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius). Nighttime lows often dip to around 35 to 40 degrees Fahrenheit (2 to 4 degrees Celsius). While these temperatures are relatively mild compared to other parts of the United States, the dampness can make it feel colder. Seattle's location near the Puget Sound and the Pacific Ocean influences the city’s moderate, marine climate. This proximity to water helps to keep temperatures from extreme fluctuations, resulting in milder winters compared to inland areas at similar latitudes. Despite the moderate temperatures, the consistent moisture and cloud cover contribute to a perception of cold, making warm clothing essential for comfort during December in Seattle.
Precipitation Levels
December is Seattle’s wettest month, with rainfall occurring on average for about 20 days. The city typically receives between 5 and 6 inches (127 to 152 mm) of rain during this period. The frequency and intensity of rainfall contribute significantly to the overall weather experience in December. The rain in Seattle is often a light, persistent drizzle rather than heavy downpours, which means that outdoor activities can still be enjoyed with proper rain gear. The high levels of precipitation are due to Seattle’s location in the Pacific Northwest, where moist air masses from the Pacific Ocean move inland and are lifted by the Olympic Mountains and the Cascade Range. This orographic lift causes the air to cool and condense, leading to frequent cloud cover and precipitation. Residents and visitors should carry umbrellas or wear waterproof jackets to stay dry throughout the month.
Daylight Hours and Sunshine
Seattle experiences some of its shortest days in December due to its northern latitude. The winter solstice, which marks the shortest day of the year, falls in December, resulting in fewer daylight hours. On average, Seattle sees only about 8 hours of daylight per day in December. The sun typically rises late in the morning and sets early in the afternoon, leaving long periods of darkness. Coupled with frequent cloud cover, the city often feels dim and gloomy during this month. The lack of sunshine can affect mood and energy levels, so many residents use light therapy lamps to combat seasonal affective disorder (SAD). Despite the limited sunshine, there are occasional breaks in the clouds, offering glimpses of blue sky and sunlight. These brighter days can be a welcome respite and provide opportunities for outdoor activities and photography.
Chance of Snow
While Seattle is known more for rain than snow, December does present a chance of snowfall. Snowfall in Seattle is variable, and some years see very little snow, while others experience several significant snow events. On average, Seattle receives a few inches of snow in December, but the exact amount can differ widely from year to year. The city’s proximity to both the Puget Sound and the Cascade Mountains influences the likelihood of snow. Cold air masses moving down from Canada can interact with moist air coming off the Pacific Ocean, creating conditions favorable for snow. However, because Seattle is at a low elevation and near the water, temperatures are often just above freezing, which means that precipitation frequently falls as rain rather than snow. When snow does fall, it often melts quickly, especially in the city center. Areas at higher elevations, such as the surrounding hills and mountains, are more likely to experience heavier and more persistent snowfall. This variability in snow conditions means that residents need to be prepared for the possibility of snow and ice, particularly if they plan to travel in or around Seattle during December.
Preparing for December Weather in Seattle
Being well-prepared for Seattle's December weather can make the month more enjoyable. This includes having the right clothing, staying updated on forecasts, and making necessary adjustments to travel plans.
Appropriate Clothing and Gear
Dressing appropriately for Seattle’s December weather is crucial for staying comfortable and healthy. The key is to wear layers, allowing you to adjust your clothing to the changing temperatures and conditions throughout the day. A waterproof and windproof outer layer is essential to protect against the rain and dampness. Look for a jacket or coat made from materials like Gore-Tex or other waterproof fabrics. Underneath your outer layer, wear insulating layers such as fleece, wool, or down. These materials will help trap body heat and keep you warm, even if they get wet. It's also important to protect your extremities. Wear a warm hat to prevent heat loss from your head, waterproof gloves or mittens to keep your hands dry and warm, and thick socks to insulate your feet. Waterproof shoes or boots are a must, especially if there is a chance of snow or icy conditions. Footwear with good traction will also help prevent slips and falls on wet or icy surfaces. Carrying an umbrella is a practical way to stay dry during the frequent rain showers. Having the right gear not only makes you more comfortable but also allows you to fully enjoy outdoor activities and explore the city, regardless of the weather.
Staying Updated on Weather Forecasts
Staying informed about the latest weather forecasts is vital for planning your activities and ensuring your safety during December in Seattle. Weather conditions can change rapidly, and knowing what to expect will help you make informed decisions about travel, outdoor plans, and other aspects of your daily life. There are several reliable sources for weather forecasts in the Seattle area. Local news channels, such as KING 5, KOMO 4, and KIRO 7, provide regular weather updates, both on television and online. These channels often have detailed forecasts, including hourly predictions, long-range outlooks, and special weather alerts. Weather websites and apps, like the National Weather Service (https://www.weather.gov/) and AccuWeather (https://www.accuweather.com/), offer comprehensive weather information, including temperature, precipitation, wind speed, and more. Many of these apps also provide push notifications for weather alerts, such as warnings for heavy rain, snow, or strong winds. Checking the forecast daily, or even multiple times a day, is a good practice during December. This is particularly important if you have outdoor activities planned or if you need to travel. Being aware of the forecast will allow you to dress appropriately, plan your route, and make alternative arrangements if necessary. If a severe weather event is predicted, such as a heavy snowstorm, it is crucial to follow the advice of local authorities and take necessary precautions to stay safe.
Adjusting Travel Plans
Travel in and around Seattle during December can be affected by the weather, so it's important to be prepared for potential delays and disruptions. The combination of rain, snow, and ice can make driving conditions hazardous, and public transportation may also experience delays or cancellations. If you are planning to drive, make sure your vehicle is in good condition and equipped for winter weather. Check that your tires have adequate tread and consider using snow tires if you live in or travel to areas that are prone to snow and ice. Keep an emergency kit in your car, including items such as a flashlight, jumper cables, a first-aid kit, blankets, and snacks. Before you set out, check the road conditions and traffic reports. Websites like the Washington State Department of Transportation (WSDOT) (https://wsdot.com/Travel/Real-time/Map/) provide up-to-date information on road closures, accidents, and other traffic incidents. If the weather is particularly severe, it may be best to postpone your trip or find alternative transportation. Public transportation, including buses, trains, and ferries, can also be affected by the weather. Check the schedules and service alerts before you travel, and be prepared for possible delays or cancellations. If you are flying into or out of Seattle-Tacoma International Airport (SeaTac), check the status of your flight before you leave for the airport. Weather conditions in Seattle and other parts of the country can impact flight schedules, so it's a good idea to stay informed and allow extra time for travel. Having a flexible travel plan and being prepared to make adjustments as needed will help you navigate Seattle’s December weather safely and efficiently.
