Factors Influencing Denali's Weather

Several factors contribute to the extreme weather conditions on Denali:

• Altitude: The higher you go, the colder it gets. Temperatures decrease by approximately 3.5°F (1.9°C) for every 1,000 feet gained in elevation.

At base camp (around 7,200 feet), summer temperatures may reach the 50s°F (10-15°C) during the day, but at higher elevations, temperatures can remain well below freezing year-round. Winter temperatures can drop to -40°F (-40°C) or colder.
