If your definition of "the West" only includes coastal states, then you've only got CA, OR, and WA to choose from. 14 US states touch the Atlantic Ocean proper, not counting the ones that abut the Gulf of Mexico which is an arm of the Atlantic, and there are vast differences in climate along either coastline. CA is a massive state with a wide range of different climates. There's New England, the Mid-Atlantic region, the South, Florida, Southern California, Northern California, and the Pacific Northwest. The climate in places in the Pacific Northwest is far more mild than places along a similar latitude on the Atlantic Coast. Winters in coastal WA state are much milder than winters in New England. And CA, OR and WA reach much farther inland than most East Coast state do. The weather in Spokane is different from the weather in Gray's Harbor County.
