Climate - Elevations on the Forest range from about 1,500 feet above sea level to 10,495 feet at the snowcapped top of Mt. Jefferson, Oregon's second highest peak. Climate on the Willamette changes with elevation. The area receives a high amount of precipitation. Much of the precipitation comes from October to April in the form of rain at the low elevations and as wet heavy snow in the higher elevations. Although snow is possible in the lowest elevations, it is infrequent. Late spring, summer and early autumn tend to bring clear, sunny days with moderate temperatures.
