An arid climate is typically marked by very little to no rainfall, leading to dry and desert-like conditions.

Arid climates, often found in deserts, are characterized by extremely low levels of rainfall, generally receiving less than 10 inches (25 cm) of rain per year. This lack of precipitation results in dry conditions, with limited vegetation and a harsh environment for most plants and animals. Arid regions experience significant temperature variations, often being very hot during the day and cooler at night. Examples of areas with arid climates include the Sahara Desert in Africa, parts of the Middle East, and southwestern U.S. deserts like the Mojave.
