Winter Weather

A wide range of weather conditions may be experienced during your visit to Great Basin National Park. Winter days can range from mild (50's) to cold (high in 30's). Nightly low temperatures are often between 10� and 30�, sometimes dropping as low as -10�. 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.
