Köppen climate types of Oregon, using 1991-2020 climate normals.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.
West of the Cascade Range, winters are chilly with frequent rain and occasional snow. Temperatures can get very cold, but only occasionally, as the result of Arctic cold waves. The high desert region of the state is much drier, with less rain, more snow, colder winters, and hotter summers.[1]
