The Willamette Valley is a region of the U.S. state of Oregon. Centered around the Willamette River, and home to the state's three largest cities and much of the state's agriculture industry and the Oregon Wine Country. This area of the Pacific Northwest was one of the first Western areas to be settled, thanks to the Oregon trail that ended in Oregon City near Portland.
The Willamette Valley has a wet climate, with about 50 inches of rain a year. It is in between an oceanic climate and Mediterranean climate. Summers are dry and somewhat warm, the rest of the year, from November to April is very wet. Snow is rare, with on average only one to three light falls a year, and a major snowstorm only a couple times a decade.
