Weather in Denali is extremely variable. Often changes in weather occur without warning. Many of our rangers tell visitors to expect sun, wind, rain, and clouds, and expect them all on the same day. Average summer temperatures range from 33 to 75 degrees Fahrenheit. While we hope it doesn't, it has been known to snow in July, so be prepared. Wearing layers of clothing makes it easy to regulate your body temperature. Also, you'll find that a good waterproof raincoat is invaluable.

Winters can be extremely cold with temperatures ranging from -40 degrees Fahrenheit and below to high 20s on warm days. Specialized cold weather gear is necessary for mountaineering and winter visits. For more information on winter visits contact park headquarters at (907) 683-2294. A winter trails map is available here in pdf format of the trails located at the front of Denali National Park.
