The Arizona Climate Guide shown above is based on the Phoenix Climate Guide. Please note that the weather may vary across this region. Below is a list of all the destinations in Arizona with available Climate Guides.

  Flagstaff   Grand Canyon   Lake Havasu City   Monument Valley   Phoenix   Show Low   Sierra Vista   Tucson   Yuma  

Located in the southwest, Arizona is one of the largest US states. Famous for its clear, sunny skies and dry weather, and boasting spectacular, diverse scenery, the state is a major tourist magnet. Many Native Americans live in Arizona, and the Navajo Reservation in the north is the nation's largest.

Flat terrain and gently sloping valleys make up the southern and western third of the State, which is home to giant saguaro cacti with their trademark candelabra branches. In summer expect extreme heat and humidity in the south, with low rainfall in the sub-tropical southwest.

Other southern areas experience the 'summer monsoon', when moisture-laden air from the Gulf of Mexico brings thunderstorms in July and August. On occasions these can also penetrate far into the northern highlands. In winter temperatures in the south are mostly comfortable with no significant rain.

From Phoenix the ground rises steadily northwards towards Flagstaff and the highlands of the Colorado Plateau. Desert cacti give way to pine and fir trees as elevation increases. Temperatures in the north are cooler in all months, but rainfall levels still remain low.

The Grand Canyon slices into the flat, dry semi-desert of the north. Over millions of years, the Colorado and other rivers have carved deep canyons, revealing coloured rocks and soil now thousands of metres deep in places. Despite the increased elevation, the north of Arizona is still warm to hot in summer. However, winters are cold to below freezing with snows on the central peaks around Flagstaff.
