The temperature variation between day and night in the Basin and Range Province is extreme.

This significant diurnal temperature range occurs due to the arid climate and clear skies typical of the region. During the day, temperatures can soar, often exceeding 100°F (38°C) in the valleys. However, at night, the lack of cloud cover allows heat to dissipate rapidly, leading to much cooler temperatures that can drop to the 40s°F (4-9°C) or lower. This extreme temperature fluctuation is a defining characteristic of the Basin and Range Province, impacting local ecosystems, agriculture, and the survival strategies of plants and animals adapted to these
conditions.
