<P> Oregon 's climate is generally mild . West of the Cascade Mountains , winters are chilly with frequent rain , while light snowfall occurs a few days a year ; 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 . An oceanic climate ( also called `` marine west coast climate '' ) predominates in Western Oregon , and a much drier semi-arid climate prevails east of the Cascade Range in Eastern Oregon . Major factors determining Oregon 's climate include the large semi-permanent high pressure and low pressure systems of the north Pacific Ocean , the continental air masses of North America , and the Cascade mountains . Oregon 's population centers , which lie mostly in the western part of the state , are generally moist and mild , while the lightly populated high deserts of Central and Eastern Oregon are much drier . </P>
