The climate classification of the Great Basin is semi-arid to arid, characterized by dry conditions and low precipitation.

The Great Basin has a semi-arid to arid climate, making it one of the driest regions in North America. This climate is marked by hot summers and cold winters, with significant temperature variations between day and night. Precipitation is scarce and mostly occurs during the winter months, with rainfall often insufficient to support extensive vegetation. As a result, the landscape is dominated by desert scrub and grasslands. This dry climate shapes the Great Basin’s ecosystems, making it a challenging environment for both plant and animal life.
