## **Overview of Marysville's Climate**
Marysville’s climate is classified as a Warm-summer Mediterranean climate (Csb in the Köppen climate classification). This results in mild, wet winters and warm, relatively dry summers. The city benefits from the Olympic Mountains to the west, which provide a rain shadow effect, lessening the rainfall slightly compared to other areas along the Puget Sound.
