Arizona is most commonly associated with an arid climate, particularly in its desert areas, where rainfall is scarce and temperatures can be extremely hot.

Arizona, located in the southwestern U.S., is a prime example of an arid climate, especially in regions like the Sonoran Desert. These areas receive very little rainfall, often less than 10 inches per year, leading to dry, desert-like conditions. The state experiences high temperatures, particularly during summer, with some areas reaching over 100°F (38°C). The lack of moisture and extreme temperatures support desert ecosystems, including cacti and other drought-resistant plants, making Arizona a typical arid region in the U.S.
