Seattle weather in October what to wear: highs around 60°F and mornings near 46°F with returning Pacific drizzle mean waterproof layers first — a hooded rain shell over sweaters and long sleeves for Pike Place, Capitol Hill, and waterfront walks, plus grippy waterproof shoes for wet sidewalks.

Based on typical October conditions in Seattle. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
October is when Seattle's rainy season returns in earnest. Highs near 60°F can still feel mild in a dry stretch, but marine air, overcast skies, and roughly eleven drizzle days make damp chill the real outfit problem — not freezing cold. City pages cover year-round Seattle style; this month guide is specifically for October rain, foliage, and cooler mornings. Dress like a local on wet days: breathable base layers, a mid-weight sweater, and a waterproof hooded shell you can bike or walk in for hours around Pike Place Market, the waterfront, and Capitol Hill. Waterproof sneakers or flat-soled ankle boots with grip beat fashion shoes on slick hills; a light scarf helps on 46°F mornings without jumping to winter parkas. Umbrellas work, but a good hood is more Seattle — and keeps your hands free on ferry decks and market stairs.
A black rain jacket over an oversized graphic tee and olive cargo trousers handles mild rain practically. White lace-up booties finish the look with enough contrast to lift the palette.
A grey longline coat over an ivory blouse and black wide-leg trousers handles mild rain without losing formal intent. Black Chelsea boots and a mini bag keep it focused.
A black longline parka over a cable knit sweater in mild rain keeps warmth without overdressing. Black mule heels under leggings are an unexpected and intentional detail.
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.
A cream oversized puffer over a navy striped cardigan and wide-leg ivory linen trousers handles mild rain with a considered mix of textures. Black ballet flats are the restrained finish.
An olive anorak handles mild rain without abandoning the polish of wide-leg navy trousers underneath. The crossbody stays tucked and close.
A blush cropped jacket over a grey cardigan and black sweater mini skirt handles mild rain with charm. A black bucket bag and ankle boots keep the proportions balanced.
Wear waterproof-first layers: long sleeves, a sweater or fleece, and a hooded rain shell for highs around 60°F and damp wind. Add water-resistant shoes and a light scarf for mornings near 46°F. Jeans or trousers dry better than light summer fabrics in persistent drizzle.
Prioritize a truly waterproof (not just water-resistant) jacket with a hood, then warm mid-layers underneath. October drizzle is frequent and lingering; staying dry matters more than packing a heavy winter coat you will overheat in during daytime walks.
It is cool rather than freezing: roughly 46–60°F. Damp air and wind off the Sound make it feel colder than the number, especially morning and evening, so plan insulated mid-layers under your shell.
Waterproof sneakers or ankle boots with grip. Pike Place, Capitol Hill hills, and waterfront pavement get slick; open shoes and smooth fashion soles struggle in the returning rainy season.
