Weather A wide range of weather conditions may be experienced during your visit to Great Basin National Park. Nightly low temperatures are often in the between 10 and 30 degrees, sometimes dropping as low as -10 degrees. Weather conditions can change rapidly, so come prepared for all possible weather. Wind is not usually a problem for hikers or skiers in wooded valleys, but the winds at ridgelines above 10,000 feet are very often 30-40 miles per hour. Hazards Avalanches are common at the high elevations in the Snake Range during the winter and spring months.
Many ski trails cross avalanche paths and run outs.
Skiers should be alert for avalanche hazards, carry proper equipment, and check with park rangers about current avalanche conditions. Winter mountaineers are urged to register at the Visitor Center. Hypothermia is always a potential danger. It is a condition in which a person's entire body temperature is lowered. It can be avoided by wearing proper clothing and being prepared for sudden changes in the weather.
