Seattle in December: Expect the Unexpected (But Pack Layers!)

Seattle in December is…complicated. Forget the stereotypical image of constant rain; while precipitation is high, it's not a simple case of relentless downpours. Understanding Seattle's December weather requires looking beyond simple averages. Let's explore what to expect based on scientific data and add some practical advice for your trip planning.

What's the average temperature in Seattle in December?

According to various meteorological data sources (and while specific numbers might slightly vary depending on the source and the precise location within Seattle), the average daily high temperature in Seattle during December hovers around 45°F (7°C), while the average low sits around 36°F (2°C). This means you'll experience a range of temperatures throughout the day. (This information is consistent with general climate data widely available, and I haven't pulled this directly from a ScienceDirect article as it's fundamental climatological data).

How much rain should I expect?

Seattle's reputation for rain is well-deserved. December is one of the wetter months. While precise rainfall amounts fluctuate annually, expect significant precipitation, often in the form of drizzle rather than torrential downpours. You'll likely need a reliable waterproof jacket and possibly rain pants. (Again, this is common knowledge reflected in numerous weather resources and not sourced from a specific ScienceDirect article).

Beyond the averages: What are the nuances?

This is where understanding goes beyond simple averages. While the average temperature might seem mild, Seattle's December weather can be surprisingly variable. You could experience a few days of unexpectedly sunny weather, interspersed with days of heavy rain and even the possibility of snow (especially at higher elevations). The crucial element is variability.

What about daylight hours?

December offers short daylight hours, typical of the northern latitude. Expect around 8-9 hours of daylight, with sunrise around 7:30 AM and sunset around 4:30 PM (times vary slightly throughout the month). This shorter daylight can impact outdoor activities and mood, so plan accordingly.

Practical Tips for a December Trip to Seattle:

• Layers are key: Pack clothing that allows for layering. A base layer, a mid-layer (fleece or sweater), and a waterproof outer layer are essential.
• Waterproof footwear: Invest in waterproof boots or shoes, as wet sidewalks and streets are common.
• Embrace the indoors: Seattle has a thriving indoor scene, with museums, art galleries, coffee shops, and restaurants providing great alternatives to outdoor exploration on rainy days.
• Check the forecast frequently: Seattle's weather can change rapidly, so checking the forecast regularly is crucial for planning daily activities.
• Consider transportation: Public transport is generally reliable, but be prepared for potential delays during periods of heavy rain.

Conclusion:

Seattle in December offers a unique experience. While the average temperatures might not be bitterly cold, the consistent rain and shorter daylight hours demand proper preparation. By understanding the nuances of Seattle's December weather and packing appropriately, you can enjoy your trip to the Emerald City, rain or shine. Remember that while I’ve used general knowledge of Seattle’s climate, detailed meteorological studies on specific aspects of Seattle’s December weather (such as the correlation between rainfall and temperature fluctuations) are available through sources like ScienceDirect, but would require specific research based on the desired focus of the analysis.
