Yellowstone Weather

Yellowstone Weather

Since most of the park lies at an elevation of 6,000 feet above sea level or higher, unpredictability characterizes Yellowstone’s weather. Expect big temperature swings, rain, or snow during every month of the year. No matter when you visit, bring a warm jacket, rain gear, and lots of layers. Temperature and precipitation can vary dramatically depending on where you are in the park. The northern range, and particularly the North Entrance region, are the driest locations in the park throughout the year.
