Washington Climate & Atmospheric Dynamics
Atmospheric Systems & Prevailing Air Masses
Washington is divided by the Cascade Mountain Range into two distinct meteorological worlds: a mild, temperate maritime western basin and an arid, continental semi-arid plateau in the east.
Key Atmospheric Drivers
Shaped by the Pacific mid-latitude cyclone storm track bringing persistent light winter rain and maritime air to the west, contrasted with the Cascade rain shadow that produces dry, sunny conditions in eastern Washington.
Statewide Seasonal Baselines
Topography & Climate Sub-Zones
Divided by the Olympic Mountains, the Puget Sound maritime depression, the formidable Cascade volcanic cordillera, and the vast Columbia River Basin and Palouse hills to the east.
Travel & Thermal Comfort Guidance
Water-resistant shells and breathable wool layers are year-round staples in western Washington, while eastern Washington requires sun protection in summer and thermal coats in winter.
