Packing List
December Packing List for Seattle — What to Wear & Bring
Pack a waterproof shell jacket worn daily, mid-weight sweaters, waterproof flat-soled ankle boots, and a waterproof bag. Seattle's December at 17 rain days is the city's wettest month — mild at 37–46°F but persistently drizzly for virtually every outing across Capitol Hill and the Pike Place waterfront.
Averages 37–46°F, ~17 days of rain
Clothing
Seattle's December is the wettest month at 17 drizzle days — the waterproof shell is the daily uniform for navigating Capitol Hill's steep wet streets, Pike Place Market's cobblestone ramps, and the Elliott Bay waterfront.
Seattle's December 37–46°F range requires mid-weight wool or fleece sweaters under the shell — the damp Pacific Northwest cold penetrates more efficiently than equivalent dry-climate temperatures.
December in Seattle requires reliable long-sleeve base layers for indoor/outdoor temperature management across the Capitol Hill coffee shop circuit, Pike Place Market, and the Seattle Center holiday events.
A chunky wool sweater is Seattle's December mid-layer under the waterproof shell outdoors and a comfortable standalone layer in the heated warmth of Capitol Hill restaurants and Pike Place Market stalls.
Seattle's December 37°F lows and 17 drizzle days make full jeans or mid-weight pants the practical choice for the persistent damp mild cold throughout the month.
Footwear
Seattle's December 17 drizzle days make Pike Place Market's cobblestone ramps and Capitol Hill's hillside streets wet for essentially the entire month — waterproof flat-soled boots are mandatory for safe navigation.
Seattle's most drizzly month requires wool socks inside all footwear — wool maintains insulation across 17 wet days, which cotton socks cannot match once damp.
For Seattle's heated indoor December destinations — Pike Place Market stalls, Capitol Hill holiday shopping, and the Seattle Center holiday events — lighter waterproof trail sneakers handle the wet approaches without full boot weight.
Accessories
Seattle's December 37°F lows and the Elliott Bay waterfront wind make a warm hat useful for all outdoor time — particularly the exposed waterfront walk between Pike Place Market and the Seattle Aquarium.
Seattle's 17 December drizzle days make light waterproof gloves practical for extended outdoor time between Capitol Hill holiday events and Pike Place Market's wet outdoor ramp approach.
The Elliott Bay waterfront at 37°F in December with Puget Sound wind is noticeably colder than the Pike Place Market covered areas — a light wool scarf adds meaningful warmth for waterfront exposure.
Seattle's December wet terrain and holiday shopping rewards hands-free carrying — a crossbody bag keeps both hands available for safe navigation of Pike Place's slippery cobblestones and Capitol Hill's steep rainy sidewalks.
Gear
Seattle's 17 December drizzle days — the rainiest of any month — make a waterproof daypack essential for protecting electronics and purchases during full days exploring Capitol Hill, Pike Place, and the waterfront.
Seattle's Pike Place Market holiday shopping and Capitol Hill boutique district are December highlights — a compact waterproof tote handles purchases in the persistent December drizzle without requiring a full backpack.
Seattle's December coffee culture is the city's primary social ritual during the gray rainy season — an insulated travel cup keeps drinks warm during Capitol Hill roaster walks between Victrola, Stumptown, and Lighthouse Coffee.
Local tips for Seattle in December
- 1.Seattle's Pike Place Market holiday season in December is the best time to buy local products — artisan food vendors, the winter flower market, and handmade craft stalls are at full holiday inventory, and the covered market provides welcome warmth during Seattle's wettest month.
- 2.Capitol Hill's holiday light installations and decorated storefronts make for a beautiful December neighborhood walk — the steep streets are wet across essentially all 17 December drizzle days, so waterproof flat-soled boots are not optional for the hillside sidewalks.
- 3.Seattle's December occasional clear days between the 17 drizzle days produce some of the year's most spectacular conditions — bright winter sun on snow-capped Mt. Rainier visible from the Elliott Bay waterfront and the Space Needle observation deck is worth planning around when the forecast clears.
