Weather InformationFor pleasant weather, the best time to visit is in the temperate spring or fall. Summer can be extremely hot in the south, with highs in the triple digits during the day. However, the north enjoys pleasant summer weather with temperatures in the 70s and 80s. The occasional thunderstorm or strong wind is common in July and August. In the south, winters are sunny and mild, with temperatures averaging 68 degrees in the afternoon. During this time, the north and east experience snow and colder temperatures.
Crowd InformationThe dramatic rise in temperature means that with the exception of families on vacation, fewer people visit the Grand Canyon in the summer. Events that attract large numbers of people include the Tostito's Fiesta Bowl in January, P.F. Chang's Rock 'n' Roll Marathon in January, Tucson Gem and Mineral Show in February, and the Cactus League Spring Training in March.
Closure InformationRestaurants, hotels, and shops stay open year-round.
When to SaveThe summer months are the most affordable in the southern part of the state.
