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.
