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.

December in Seattle ushers in the city's quintessential cool, damp, and decidedly grey weather. Expect average daytime temperatures ranging from the low to mid-40s°F (5-7°C), with nighttime lows hovering in the mid-30s°F (2-4°C). While heavy snowfall is uncommon, light flurries can occur, though persistent rain remains the primary precipitation. December is historically one of Seattle's wettest months, characterized by frequent drizzles and persistent overcast skies rather than intense downpours. The short daylight hours and pervasive dampness mean strategic layering is paramount for comfort. To navigate Seattle's December climate stylishly and practically, prioritize warmth and waterproofing. A high-quality, waterproof and windproof outer jacket is non-negotiable – ideally one with a hood. Beneath, build your outfit with moisture-wicking base layers, followed by insulating mid-layers like wool sweaters or fleece. For footwear, waterproof boots with good traction are essential for comfortable exploration of the city's hills and waterfronts. Don't forget accessories: a warm hat, gloves, and a scarf will provide crucial extra protection against the brisk air and persistent dampness, ensuring you stay cozy while enjoying the festive Pacific Northwest atmosphere.
