What & Why: Understanding Donner Pass Weather

Donner Pass weather is characterized by its dramatic shifts and extremes, largely due to its high elevation (over 7,000 feet) and location in the Sierra Nevada mountain range. The pass acts as a significant barrier, intercepting moisture-laden air masses from the Pacific Ocean, resulting in heavy snowfall during winter and variable conditions throughout the year.

Winter Weather in Donner Pass

Winter (November to April) is the most challenging season in Donner Pass. Heavy snowfall is common, with average annual snowfall exceeding 400 inches. Temperatures frequently drop below freezing, and blizzards can occur, reducing visibility and creating hazardous driving conditions. Chain controls are often in effect, and road closures are possible.

• Risks of Ignoring Winter Weather: Disregarding winter weather warnings can lead to accidents, getting stranded, and potential health risks such as hypothermia.
