On average, Seattle experiences rain on about 20 days in December, contributing to a general perception of the month being quite damp and gray. The average total rainfall in December is around 5.5 inches (140 mm), which is considerably higher than many other months.
The type of precipitation is primarily rain, but Seattle does occasionally see snow in December. Snowfall is less common than rain, but when it does occur, it can sometimes lead to disruptions in transportation and daily routines. The chances of a significant snowfall event are relatively low, but light snow or flurries are not unusual. The combination of rain and the possibility of snow means that having appropriate footwear and outerwear is crucial for navigating the city comfortably.
Due to the consistent rainfall, Seattle's atmosphere in December is often humid, which can amplify the feeling of cold. This high humidity means that even temperatures in the 40s Fahrenheit can feel quite chilly. The city's location near the Puget Sound and the Pacific Ocean contributes to this maritime climate, which is characterized by wet winters and mild, relatively dry summers. For updated information on precipitation patterns and forecasts, the National Oceanic and Atmospheric Administration (NOAA) (https://www.noaa.gov/) offers comprehensive data and resources. To fully enjoy December in Seattle, it’s advisable to invest in waterproof clothing, including a reliable rain jacket, waterproof boots, and perhaps even waterproof pants.

Understanding the frequency and amount of rainfall helps in planning your days and ensuring you are adequately prepared for the weather conditions.
Daylight Hours and Sunlight in December
December in Seattle marks the time of year with the fewest daylight hours. The winter solstice, which usually falls around December 21st, represents the shortest day of the year, and daylight hours are significantly reduced throughout the month. On average, Seattle experiences around 8 hours of daylight in December. This limited sunlight can influence daily life, affecting everything from mood and energy levels to outdoor activities and travel plans.
The sun typically rises quite late and sets early, resulting in long evenings. Sunrise in late December occurs around 7:45 AM, and sunset is approximately 4:20 PM. This short window of daylight means that much of the day is spent in either twilight or darkness. The reduced exposure to sunlight can impact people's circadian rhythms and contribute to seasonal affective disorder (SAD), a type of depression related to changes in seasons.
Seattle's skies are often overcast in December, further diminishing the amount of direct sunlight. The combination of cloud cover and short daylight hours can make the city feel quite gloomy. To cope with the limited sunlight, many residents use light therapy lamps, which mimic natural light and can help alleviate symptoms of SAD. Additionally, planning indoor activities and events is a popular way to stay active and engaged during the darker months. Despite the limited daylight, Seattle embraces the holiday season with festive lights and decorations, adding warmth and cheer to the city's ambiance. Websites that track sunrise and sunset times, such as Time and Date (https://www.timeanddate.com/), can help you plan your day around the available daylight. Maximizing your exposure to natural light during the day, even if it’s limited, can positively influence your well-being. Understanding the daylight patterns in December allows for better planning of activities and helps in managing the effects of reduced sunlight exposure.

Effective preparation includes dressing appropriately, planning for potential travel disruptions, and taking necessary health precautions. The city's cool temperatures, frequent rainfall, and limited daylight hours require a thoughtful approach to daily activities and overall well-being. Dressing in layers is highly recommended. This allows you to adjust your clothing to changing conditions and maintain a comfortable body temperature. Start with a moisture-wicking base layer, add an insulating middle layer such as fleece or wool, and top it off with a waterproof and windproof outer layer.
Waterproof footwear is essential for navigating the wet streets, and a sturdy umbrella or a hooded rain jacket is a must-have. Gloves and a warm hat can also make a significant difference in staying warm, especially during colder snaps. Beyond clothing, it's crucial to plan for potential travel disruptions.

From a health perspective, the reduced sunlight can impact vitamin D levels, so consider taking a supplement if recommended by your healthcare provider. Maintaining a healthy diet and staying active can also help boost your immune system and overall well-being during the darker months. Additionally, being aware of the potential for seasonal affective disorder (SAD) and seeking help if needed is important. Overall, preparing for Seattle's December weather is about being proactive and informed.
