What to expect
Daytime
Cool days in Seattle: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.
Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.
Rain
Mixed skies in Seattle in October. Dry days and wet days share the month. Outdoor plans need a backup, not a cancellation policy.
Pack a shell you will actually carry. The monthly table is the place for totals. This is the feel: usable, interrupted.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
Rain jacket
A layer for cooler evenings
