The climate of Oregon (United States of America)
The state of Oregon is located in the northwestern part of the United States. Several mountainous regions can be found in Oregon due to the influence of plate tectonics. Impressive mountains are alternated by even more impressive lakes. The combination of high mountains and large lakes attract many people who like peace and quiet. One of the most important attractions in Oregon is Crater Lake, with a depth of 600 meters this is the deepest lake in the United States. Oregon has a mix of Mediterranean and continental climate types with dry summers and fairly wet winters in the entire state. Based on precipitation figures a small region in the southern part of Oregon has a cold steppe climate. during the winter depressions are supplied from the relatively warm Pacific Ocean causing precipitation figures to be high during this period. However, there are large differences in precipitation figures. This is mainly caused by the mountainous regions which may cause very high precipitation figures in one particular region. Precipitation figures are much lower on the leeward side of the mountains. Because of the influence of the ocean chances of subzero temperatures and snowfall are much smaller here than in the interior.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The figures below apply to Salem. For climate figures on specific regions and places please, visit the relevant individual climate pages
