Barometric pressure

Salem is situated in the Willamette Valley. The valley is surrounded by mountains to the east and west. These mountains restrict air movement. They block air from the Pacific Ocean and the eastern United States.

This blockade affects the atmospheric pressure in Salem. It creates a rain shadow effect. Moist air from the Pacific Ocean hits the western mountains. It cools and drops most of its rain. The dry air then moves into the valley.

As a result, Salem's weather is generally mild and dry. The city experiences some rainfall throughout the year. However, it is less than in the surrounding mountains.
