Washington, Oregon, California: Not Uniformly Mild & Rainy – Diverse Climates

The premise is incorrect. These three states span extraordinary climate diversity:

Washington

• West Cascades: Marine west coast – mild, wet (Seattle: 37" rain, 150+ cloudy days)
• East Cascades: Rain shadow – semi-arid (Spokane: 17", 300 sunny days), hot summers, cold winters

Oregon

• Coast/Willamette Valley: Mild, wet winter / dry summer (Portland: 36", Mediterranean)
• High Desert (East): Arid, extreme temps (Bend: 11", -10°F to 95°F)

California

• North Coast: Cool, foggy, wet
• Central Valley: Hot dry summer, foggy winter
• Deserts (Mojave, Colorado): Hottest/driest US (Death Valley)
• Mountains: Alpine, deep snow
• South Coast: Mediterranean (LA: 15", 284 sunny days)

Correction

Spelling: Washington, Oregon, California (not "washingtonoregonand"). Only west-of-Cascades lowlands are mild/rainy. The region encompasses rainforests, deserts, alpine, Mediterranean, and continental climates.
