Trewartha climate types of Oregon. According to the Köppen climate classification, most of Western Oregon has a warm-summer Mediterranean climate (or Csb type), which features warm, dry summers, and wet winters with frequent overcast and cloudy skies. Eastern Oregon falls into the cold semi-arid climate (or BSk type), which features drier weather.
The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1
The patterns in a climograph describe not just a location's climate but also provide evidence for that climate's relative geographical location. For example, a climograph with a narrow range in temperature over the year might represent a location close to the equator, or alternatively a location adjacent to a large body of water exerting a ...
The climate of the Willamette Valley is a mix of Mediterranean (Köppen Csb) and oceanic (Köppen Cfb) influences. The Köppen climate classification system considers it Mediterranean, but compared to a true Mediterranean climate it is cooler and moister, with a longer rainy season.
"Climate change can increase the frequency and severity of fires that burn forests, grasslands, and desert vegetation. Since 1984, about 4 percent of the land in Oregon has burned per decade. The changing climate is likely to more than double the area in the Northwest burned by forest fires during an average year by the end of the 21 st century.

The Willamette Valley ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington.Slightly larger than the Willamette Valley for which it is named, the ecoregion contains fluvial terraces and floodplains of the Willamette River system, scattered hills, buttes, and adjacent foothills.
