Oregon

Climate in Oregon

Oregon's climate is generally moderate, divided into east and west by the Cascade Mountain Range. The mountains block the moist winds blowing in from the sea, which moderates the temperature and brings heavy rainfall to the western part of the state, where most of the main cities are situated.

The eastern part of Oregon has drier weather and more extreme temperatures. Average temperatures range from 45F (7C) in winter and 68F (20C) in summer along the coastal belt, to 25F (-4C) and 78F (26C) in the eastern part of the state. Heavy snowfalls are common in the Cascades in winter.
