Climate - The climate of Washington varies within each region. The Cascades split the state and alter the weather patterns. The terrain east of the mountains, which includes Potholes State Park, receives approximately 12 inches of rainfall per year, generally much less than west of the mountains. Since the area east of the mountains is landlocked, temperatures in this region are lower during the winter months. Frequent winds coming down from the mountains also contribute to the low temperatures of eastern Washington.
Potholes State Park, in south central Washington, is located In Grant County, 20 miles southwest of Moses Lake.
