Climate - Climate in Eastern Oregon varies greatly with elevation. The higher elevations experience colder temperatures and higher precipitation than the lower elevations. The region is much more arid and experiences greater temperature variations than western Oregon. Much of Eastern Oregon is considered high desert, where in some areas annual precipitation is less than 10 inches. Summer temperatures often reach 90 degrees in the lower elevations. Winters can be bitterly cold here, although there is little humidity. The mountains can receive heavy snowfall. If visiting the region during the summer months be prepared for afternoon thunderstorms and chilly evening temperatures. Snow may be encountered on high country trails throughout the summer months.
