Rain Jacket Zip Layer
A black rain jacket over a white zip-up hoodie is the light-rain sporty combination that stays clean in colour. Fleece leggings and Chelsea boots handle the rest.
What to Wear in Seattle in December
December in Seattle is the city's wettest month, with highs averaging 46°F and lows near 37°F across roughly 17 days of precipitation — a genuine waterproof shell and waterproof footwear are not optional. Pike Place Market, the Capitol Hill neighborhood, and the Elliott Bay waterfront are atmospheric under persistent drizzle but require full rain gear to enjoy without arriving soaked. Seattle's rain tends to come as relentless light drizzle rather than heavy downpours, which makes a proper shell more essential than an umbrella.

Based on typical December conditions in Seattle. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
Seattle's December rain isn't dramatic — it's relentless. The Pacific storm systems deliver a persistent, fine drizzle across an average of 17 days, the Elliott Bay waterfront runs gray under low clouds, and the iconic view of Mount Rainier disappears for weeks at a time behind overcast. Highs average only 46°F with lows near 37°F, and the marine influence keeps the air damp in a way that penetrates non-waterproofed clothing quickly. The compensation is that Seattle's indoor and covered culture — Pike Place Market's arcade, Capitol Hill's dense coffee shop concentration, the Seattle Art Museum — is excellent precisely because it evolved for this weather. The local style tendency is Gore-Tex practical meets Pacific Northwest outdoorsy: Arc'teryx or Patagonia shells over fitted Merino wool layers, Blundstone or Danner waterproof boots, and dark technical fabrics that handle both the trail and the espresso bar. Locals don't use umbrellas — the sideways Pacific gusts render them ineffective, and a proper hood is always cleaner in practice. Visitors who arrive with only a stylish but unlined rain shell and canvas sneakers typically recalibrate their kit by day two.
Curated Looks
Cute
Lilac Vest Cream Stack
A pastel lilac vest over a cream cardigan and wide-leg sweatpants reads softly in light rain. Black Chelsea boots are the only contrast in this muted palette.
Casual
The Rust Shacket
A rust plaid shacket works as jacket and top layer in light rain. Suede knee-high boots and a cream maxi skirt carry the look when the weather clears.
Cozy
Hoodie Under the Parka
A black longline parka over an oversized hoodie and fleece-lined leggings handles everything light rain brings. Tan Chelsea boots and a grey scarf soften the all-black stack.
Formal
Grey Coat Formal Rain
A grey longline coat over camel trousers and a black turtleneck holds formal presence through light rain. The black mini shoulder bag keeps what needs carrying close.
Business Casual
Camel Coat Patent Thigh
A camel coat over dark jeans and a black crewneck gains editorial edge from patent leather thigh-high boots in light rain. A canvas tote keeps the rest functional.
Chic
Camel Coat Maxi Combat
A camel coat over a black turtleneck and cream maxi skirt cuts a strong silhouette in light rain. Black combat boots under the skirt are the editorial surprise that makes it.

Frequently Asked Questions
What should I wear in Seattle in December?+
A seam-sealed waterproof shell with an adjustable hood is the essential foundation — Seattle's December drizzle is nearly constant, and 17 days of precipitation means sustained exposure rather than brief showers. Layer a Merino wool or synthetic fleece mid-layer and moisture-wicking base underneath. Waterproof boots with a grip sole handle the Capitol Hill and Pike Place area's wet pavement and the uneven Elliott Bay waterfront boardwalk. Skip the umbrella — Pacific gusts make them ineffective.
Is December a good time to visit Seattle?+
Seattle in December is uncrowded and genuinely appealing for visitors who embrace the indoor culture. Pike Place Market is at its atmospheric best without summer tourist congestion, the Seattle Art Museum's winter exhibitions are accessible, and the city's legendary coffee shop culture (Victrola, Lighthouse, and the original Starbucks on Pike Place) provides constant warm refuge. ZooLights at Woodland Park Zoo runs through December. The weather is genuinely challenging — 17 days of precipitation — but the city is built for it.
What shoes are best for Seattle in December?+
Waterproof boots are the only practical choice — Seattle's December sidewalks and the Pike Place Market arcade stay perpetually wet. Blundstone-style Chelsea boots in waterproof leather handle urban walking with minimal weight and bulk. For any outdoor activities like Discovery Park or the Arboretum trails, a waterproof hiking boot with a grip sole handles the wet and muddy trail conditions. Avoid canvas sneakers, non-waterproofed leather, or any fabric shoe — they'll be soaked within the first hour outdoors.
How cold and wet does it get in Seattle in December?+
Temperatures average 37–46°F with rare extremes — Seattle's marine climate keeps temperatures from dropping far below freezing or rising far above 50°F in December. The defining characteristic is moisture: about 17 days of precipitation, almost entirely as fine drizzle or steady rain, plus persistent overcast that makes the cold feel more penetrating. Snow in the city proper is uncommon but possible; the Cascade Mountain passes see significant snow accumulation.
What should I pack for Seattle in December?+
Pack a seam-sealed waterproof shell with a hood, Merino wool or synthetic base layers, a fleece or wool mid-layer, waterproof boots, wool socks, and a wool beanie. Leave the umbrella at home. A waterproof daypack keeps electronics and dry layers protected during long outdoor stretches. Seattle's indoor venues are warm and well-heated, so you'll remove layers quickly once inside — plan for easy on/off outer layers.
