What to Wear in Portland in Winter: Month-by-Month Outfit Guide
Portland in winter sits in the 30 to 50°F range. This is the layer-by-layer outfit guide for Portland's winter weather — what to wear, what to pack for a visit, and the local context that shapes the recommendations.
WHAT TO EXPECT
Portland in winter — December, January, February. November through March. 40-50°F highs, 30-40°F lows. Rain rather than snow most years. Water-resistant breathable shell over wool layers. Quality treated leather boots or technical hikers. The temperature range is the headline; what you actually feel depends on humidity, wind, and what indoor spaces you'll cycle through.
THE FOUNDATION LAYER
A lightweight merino or technical long-sleeve under your shirt or sweater handles the temperature swing.
THE MID LAYER
A wool sweater or insulated vest carries you between the base and the outerwear. In Portland's winter, this layer comes off the moment you're indoors.
THE OUTERWEAR
A wool topcoat, trench, or insulated shell. A waterproof shell is more useful than a heavier wool coat — coastal rain has no off-season.
ACCESSORIES
Wool scarf, knit hat for cold mornings, gloves for the commute. Boots over sneakers.
WHAT TO PACK FOR A TRIP TO PORTLAND IN WINTER
Three layer permutations covering the 30 to 50°F range, plus accessories. If your trip spans the season's edge (late November or early March), pack toward the cooler end of the range — overestimating warmth is easier to recover from than underestimating.
LOCAL CONTEXT
Locally, hoods over umbrellas. The light persistent rain demands different gear than tropical downpours. A breathable shell with DWR is the most useful piece. Wool sweaters and casual outerwear define the Portland style.
