Christmas in Washington usually brings gray skies, chilly air, and a mix of rain and snow depending on where you end up. You’ll find average temperatures around Christmas range from the mid-30s to mid-40s Fahrenheit in western Washington, while eastern Washington runs colder and drier. Snow shows up often in the mountains, but the lowlands—especially near Seattle—usually get more rain than snow.
The holiday season feels different in each part of the state. In the Cascades and mountain towns, snow creates classic winter scenes that are perfect for skiing or a festive getaway.
Along the coast and in the big cities, rain and overcast days tend to dominate, but holiday lights and events really brighten things up.
If you know what kind of weather to expect, you’ll plan better, whether you want snowy adventures or cozy city celebrations. Washington’s varied climate lets you pick the Christmas atmosphere that fits your plans, from snowy slopes to bustling holiday markets.
Overview of Washington’s December Climate
December in Washington brings short days, frequent rain or snow, and some of the coldest temperatures of the year. Weather patterns shift sharply depending on your location.
The state’s geography plays a major role in how conditions vary from coast to mountains to inland valleys.
Regional Weather Differences Between Western and Eastern Washington
Western Washington—including Seattle, Tacoma, and the Olympic Peninsula—stays relatively mild but very wet. Daytime highs usually land between 7–9°C (45–48°F), while nights dip close to freezing.
Rain rules the forecast, though higher elevations like Olympic National Park pick up heavy snow.
Eastern Washington, split off by the Cascade Range, feels colder and drier. Cities like Spokane and Yakima often reach daytime highs around 1–4°C (34–39°F) and nighttime lows well below freezing.
Snow falls more often here than rain, and icy roads can be a real concern.
This west-to-east contrast means you might drive from soggy gray skies into crisp, snowy landscapes in just a few hours. The difference jumps out if you cross mountain passes like Snoqualmie or Stevens, which often need chains in winter.
Influence of the Pacific Northwest Geography
The Cascade Range acts as the main dividing line for Washington’s December climate. Moist air from the Pacific Ocean rises over the mountains, dropping heavy rain and snow on the western slopes.
This pattern creates a wet, cloudy environment for western Washington.
On the eastern side, the mountains block most of the moisture. That leads to colder but drier conditions.
This “rain shadow effect” stands out in places like Yakima and the Columbia Basin.
The Olympic Peninsula adds another twist. The west side, near Olympic National Park, gets some of the heaviest rainfall in the continental U.S. during December.
In contrast, the northeast part of the peninsula, including Sequim, stays drier because the Olympics shield it from storms.
Typical December Weather Conditions
December is one of the darkest months in Washington, with barely any sunshine. Seattle averages only about 50–70 hours of sun for the whole month.
Cloud cover is frequent. Daylight lasts just eight to nine hours.
Rainfall is high in western Washington, often topping 140–170 mm (5–7 inches) in cities like Seattle and Bellevue. Snow is rare at sea level but common in the Cascades, where totals can reach several feet.
In eastern Washington, snow happens more often. Spokane, for example, averages several inches of snow in December, with temperatures often below freezing.
Roads get slick, and travel delays aren’t unusual.
If you plan to visit mountain areas, prepare for harsh winter conditions. Mount Rainier and the Cascades often see subzero temperatures and deep snowpack, so you’ll need proper gear and some preparation.
Average Temperatures Around Christmas
Temperatures in Washington during Christmas swing pretty widely depending on where you are. Coastal cities stay cool and wet, inland areas get colder and drier, and the mountains drop well below freezing with heavy snow.
Seattle Temperature Patterns
In Seattle, daytime highs usually reach about 45°F (7°C), with nighttime lows near 35°F (2°C). Rain is common, and December averages about 140–170 mm of precipitation spread across 18–21 days.
Snow doesn’t show up often, and when it does, it’s usually light and gone quickly.
The damp air and constant clouds make it feel colder than the thermometer says. You’ll want a waterproof jacket, warm layers, and shoes that can handle wet sidewalks.
Sunshine is in short supply, with only 50–70 hours during the month.
Seattle’s mild but wet conditions mean a white Christmas is rare, but you should get ready for chilly, damp air almost every day.
Spokane and Eastern Washington Temperatures
Spokane and the rest of eastern Washington feel much colder than the coast. Around Christmas, daytime highs usually hit 33°F (1°C), and nighttime lows often fall to 23°F (-5°C) or even lower.
Snow is much more likely here, and the region often has several inches on the ground by late December.
The drier climate east of the Cascades means less rainfall than Seattle, but frequent snow showers and icy roads are common.
Clear skies pop up more often, which can bring very cold nights.
If you’re heading to Spokane during the holidays, expect a strong chance of a white Christmas. Bring insulated clothing, gloves, and boots that work for snow and ice.
Mountain and Coastal Area Temperatures
The mountains, including Mount Rainier and Mount Baker, are some of the coldest places in the state. Around Christmas, daytime highs can hover near 20°F (-6°C), and nights drop well below 10°F (-12°C).
Snowfall gets heavy, with several feet piling up through December. These conditions make the mountains perfect for skiing, but also hazardous for travel.
Along the Washington coast, towns like Ocean Shores and Ilwaco stay milder. Daytime highs reach about 46°F (8°C), and lows hang near 39°F (4°C).
Rainfall is heavy, often passing 150 mm in December, and storms sometimes bring strong winds.
The coast offers a wet but less frigid holiday climate. Meanwhile, the mountains deliver true winter cold and deep snow.
Rainfall and Precipitation in December
December in Washington brings steady wet weather, with both rainfall and snowfall depending on your location.
Coastal cities get frequent rain, while the mountains receive heavy precipitation that often falls as snow.
Eastern Washington tends to be drier, though it still gets measurable rainfall.
Rainfall Amounts in Major Cities
If you’re in western Washington cities like Seattle, you can expect an average of about 5.7 inches of rain in December. Rain falls on roughly 18 days, making it one of the wetter months.
The rain usually comes as light to moderate showers rather than heavy downpours.
Farther south, Olympia averages nearly 8 inches of precipitation for the month. Vancouver and Tacoma each get about 6 to 7 inches, spread across 20 days or more.
These areas sit right in the path of Pacific storm systems that bring lots of wet weather.
In contrast, Spokane in eastern Washington averages only 2.3 inches of precipitation in December. Rain and snow mix more often here, and the number of wet days is lower, usually around 14.
This difference highlights the strong west-to-east divide in Washington’s winter climate.
Precipitation in Mountainous Regions
The Cascade Mountains collect some of the highest precipitation totals in the state during December. At places like Baker Lake Dam and Baring, totals often reach 14 inches or more.
Most of this falls as snow at higher elevations, building the winter snowpack.
Stevens Pass, a popular mountain crossing, typically gets heavy snowfall during December. While it’s tough to separate rain from snow totals, you can expect steady precipitation nearly every day.
Travel across the pass can be challenging, but ski areas in the region benefit from all that snow.
In the Skagit Valley, rainfall is shaped by its location near the mountains. Towns in the valley average 4 to 5 inches of precipitation in December, less than the higher Cascade slopes but still wetter than many eastern locations.
The valley often deals with cloudy, damp days and light rain.
Rainfall Table for Key Locations
Here’s a table showing average December precipitation for selected places across Washington. Totals include both rainfall and melted snowfall.
| Location | Inches | Millimetres | Days of Precipitation |
|---|---|---|---|
| Seattle | 5.7 | 145 | 18 |
| Olympia | 7.9 | 199 | 20 |
| Vancouver | 6.8 | 172 | 20 |
| Spokane | 2.3 | 59 | 14 |
| Stevens Pass* | High snow totals, often 100+ inches snow equivalent | , | 20+ |
| Skagit Valley | 4–5 | 100–125 | 17–19 |
*Stevens Pass values reflect snow-dominated precipitation rather than rainfall.
Snowfall and Winter Weather Conditions
Snowfall in Washington really depends on your location. Coastal cities see only light snow, while mountain regions build deep snowpack that supports skiing, snowboarding, and other winter sports.
Travel conditions can change quickly, especially around mountain passes.
Snowfall in Urban Areas
Western cities like Seattle, Olympia, and Bellingham get limited snowfall that often melts quickly. Seattle averages about 6 inches per year, while Olympia sees closer to 4 inches.
Snow events are usually brief, with rain returning soon after.
Eastern Washington cities such as Spokane and Pullman experience much heavier snowfall. Spokane averages around 45 inches annually, and snow often stays on the ground for weeks.
Towns like Yakima and Wenatchee also see regular snow, though totals are lower than Spokane.
Snow in urban areas can disrupt roads, but it rarely lasts long in the west. In the east, expect icy conditions and packed snow on side streets through late December.
Mountain Snowpack and Ski Destinations
The Cascade Mountains get some of the heaviest snowfall in the state. Places like Mount Baker average more than 600 inches annually, which is among the highest totals in North America.
Stevens Pass, Crystal Mountain, and Mount Rainier National Park also build a deep snowpack by Christmas.
These areas are prime spots for skiing, snowboarding, and snowshoeing. Resorts often open by late November, with December providing reliable conditions.
Leavenworth, a Bavarian-themed town in the eastern Cascades, draws visitors for its festive holiday atmosphere and easy access to mountain snow.
Snowpack in the Cascades isn’t just about recreation. It also supports water supply and ecosystems across the state, making early-season accumulation a key feature of the winter climate.
Travel Considerations During Christmas
If you plan to drive across Washington during Christmas, expect changing road conditions. Mountain passes such as Snoqualmie and Stevens see heavy snow, ice, and chain requirements.
Delays are common when storms roll through.
On the west side, you might face wet roads and occasional slush. In the east, snow-covered highways are more likely, with colder temperatures keeping surfaces slick.
Air travel can also take a hit when snow reaches Seattle-Tacoma or Spokane International Airport. To reduce stress, keep an eye on Washington State Department of Transportation (WSDOT) updates and allow extra time for winter travel.
Popular Christmas Destinations and Activities
Washington offers a mix of small-town charm, outdoor recreation, and cultural attractions during the holiday season. You’ll find festive lights, winter sports in the mountains, and indoor experiences that highlight the state’s history and arts.
Festive Towns and Holiday Events
Leavenworth stands out as one of the most visited holiday towns in Washington. Its Bavarian-style buildings glow with thousands of lights each December, and you can join in caroling, parades, and seasonal markets.
Families often plan whole weekends around the tree lighting and strolling through the decorated streets.
Other towns get festive too. Walla Walla hosts wine tastings paired with holiday events, while Lake Chelan offers winter festivals and waterfront light displays.
In coastal areas, the San Juan Islands feature small-town parades and local craft markets.
Seattle adds an urban twist with its Pike Place Market holiday displays and waterfront light shows. You’ll also find community events in Tacoma, Spokane, and smaller historic towns that decorate main streets with lights and host local performances.
Outdoor Activities and Winter Sports
Washington’s got such a mix of landscapes, so you can pick from all kinds of winter recreation. The Cascade Mountains usually get enough snow for skiing, snowboarding, or snowshoeing.
People flock to resorts near Stevens Pass and Crystal Mountain, but you’ll also find smaller hills with family-friendly slopes. That’s pretty handy if you want to avoid the crowds.
If hiking’s more your thing, you can still hit some lower-elevation trails in winter. Around Lake Chelan and the Columbia Gorge, you’ll see routes perfect for cold-weather walks with snowy views.
But always check the conditions before you go. Trails can get icy or sometimes close up after storms.
Ice skating rinks pop up in a bunch of towns, like Spokane and Seattle. It’s a fun way to get outside even if you’re not into skiing.
Out in rural spots, people love cross-country skiing and sledding. These activities let you mix festive town visits with some fresh air.
Indoor Attractions and Cultural Experiences
When you need a break from the cold, you’ll find plenty of indoor things to do in Washington. Seattle’s Museum of Pop Culture runs exhibits on everything from music history to movies, and honestly, it’s a solid pick for families.
The Pacific Science Center and local theaters put on holiday programs too. That’s always nice if you want something festive but warm.
Wine tasting? Absolutely—regions like Walla Walla and Woodinville do it right. Wineries decorate their tasting rooms with lights and offer seasonal pairings, so you can soak up the holiday spirit in a quieter spot.
Markets and galleries give you more ways to stay inside. Pike Place Market fills up with artisan stalls and holiday goods, and smaller towns set up craft fairs in community centers.
It’s a great way to experience Washington’s culture without spending your whole day out in the cold.
Tips for Visiting Washington at Christmas
Christmas in Washington means chilly weather, shorter days, and maybe even snow if you’re lucky. You’ll want to prep for the cold, think ahead about travel conditions, and figure out where to see the best seasonal scenes.
Packing and Clothing Recommendations
Daytime highs usually sit in the 40s °F (4–9 °C), but at night, temps often drop into the 20s °F (-2 to -6 °C). Snow might show up, but you can’t count on it, so pack with flexibility in mind.
Grab a warm winter coat, insulated gloves, a knit hat, and a scarf. Layering really helps since indoor places crank up the heat, but outside can feel pretty raw.
A thermal base layer under sweaters works well if you’re planning long days out.
Don’t forget about footwear. Pick water-resistant boots with decent traction for icy sidewalks. If you’re thinking about parks or trails, go for hiking shoes made for wet and cold weather.
For evenings out, locals tend to dress smart, even in the winter. A wool coat and leather gloves keep you warm and looking sharp.
Travel Planning and Safety
Holiday travel gets busy, and snow or ice can mess with road conditions. If you’re driving, leave extra time and keep supplies like a scraper, flashlight, and blanket in your car.
Public transit—especially the Metro—usually stays reliable when snow falls. Underground lines tend to remain open, even during storms.
Book a place to stay near the sights you want to visit so you don’t have to travel too far. If you’re heading to monuments or outdoor memorials, check the forecast first, since the weather can turn suddenly.
For air travelers, winter storms on the East Coast sometimes cause delays. Keep your plans flexible and watch airline updates closely.
Best Places for Scenic Winter Views
Washington itself gives you some striking winter scenery at spots like the National Mall and Rock Creek Park. The wider region also has some truly memorable landscapes.
If you venture farther, you’ll find the Columbia River Gorge delivers dramatic cliffs and waterfalls, all framed by winter mist. The Hoh Rainforest in Olympic National Park stays green year-round, and mossy trees often catch a dusting of frost.
Snow covers the peaks in North Cascades National Park or around Mount St. Helens, and those places offer excellent photo opportunities. In late December, the Skagit Valley feels quieter, but you still get those wide views of farmland and mountain backdrops.
Closer to the city, you can check out the Potomac River overlooks. The U.S. Botanic Garden also brings a mix of natural and festive scenery, which feels surprisingly cozy in winter.
