Great Basin National Park - Climate

Climate

The park lies in an arid region and receives very little rainfall during most of the year. Most precipitation is winter snow or summer thunderstorms. All precipitation in this region evaporates, sinks underground or flows into lakes. No water reaches the ocean.

Winters are cool and summers are mild to hot. Weather can change quickly, especially in the back country or on Wheeler Peak at high elevations. Lehman Caves maintains a fairly constant temperature of 50 °F (10 °C) with 90% humidity year round.
