Reply #5: Oregon has at least six climates [View All]

The Coast--almost always cool, but never too cold, very rainy during the winter
The Willamette Valley--warmer in the summer and colder in the winter than the coast, with rain in the winter, sometimes snow
The Gorge--wet in the west, dry in the east, and very, very windy, a prime spot for windsurfing
Eastern Oregon--high desert with rocks and sagebrush, but colder in the winter than the Willamette Valley. Surprising to people who think of Oregon as "the place where it rains all the time."
The Cascades--mountains with lots of snow in the winter, cool in the summer
Southern Oregon--like the Willamette Valley, but much hotter in the summer

West of the Rockies, the climate bands tend to run vertically rather than horizontally, and they're dependent on closeness to the ocean and/or mountains.
