Best Time to Visit Pacific Northwest (Seattle & Olympic) (North America)

North America · Month-by-month weather, seasons and what to do — from Noura's Destination Finder.

Noura's timing tip: This is the Northwest, so expect grey skies and drizzle from October through May; July to September is the reliably dry, sunny window. Mount Rainier's Paradise road and Olympic's Hurricane Ridge road can close for snow well into spring, so check conditions before mountain day-trips.
