What to Wear in Seattle
Seattle's reputation for rain is mostly true — it rains ~150 days per year. The reputation for cold is overstated. The real Seattle climate is mild, gray, and damp. The right wardrobe is built around water-resistant outerwear, layered fabrics, and quality footwear.
What to wear in Seattle today
Today's answer depends on today's conditions, so the specific outfit comes from the live reading for Seattle rather than from this page. Check what to wear right now, or read on for what stays true here whatever the date.
Three things move the answer in Seattle more than the forecast number does: the feels-like temperature rather than the air temperature, how long you will be outside, and whether you run warm or cold. Oceanic (cool, wet) conditions make that gap wider here than the daily high suggests.
Locals do not use umbrellas — they use hoods. A water-resistant breathable jacket is the most useful single garment in Seattle. Light rain (Seattle's typical) demands a different jacket than heavy rain (a Gore-Tex shell with sealed seams).
