Mesa has a tropical and subtropical, hot desert type of climate (Köppen climate classification BWh) with scorching summers and mild winters, and a meager amount of rainfall. It is a suburban city in the Maricopa County of Arizona, east of Phoenix, in the southwestern United States.

The town lies in one of the driest and hottest regions in the United States with annual precipitation of barely 9.3" (236.2mm). The rainfall occurs in small quantities throughout the year, but the area is prone to thunderstorms and flash floods. The flatlands and arid landscape are unable to hold water, and a sudden burst of rain causes flooding. Snow is mostly absent in the far southern desert areas of the United States.

The worst time to visit Mesa is during the period from June to September when the sun is scorching, and the blistering heat is unbearable most of the time. Summer is prone to thunderstorms, and moderate rainfall causes flash floods, as the landscape is unable to hold even small quantities of water due to lack of vegetation.
