There’s no doubt that Arizona is a gorgeous state to visit. Arguably the best time to visit Arizona’s most popular destination, the Grand Canyon, is during the winter months of December through February. During this time, the weather is mild and quite sunny. September through April, on the other hand, is the most ideal time to pay a visit to the southern cities of Arizona such as Phoenix and Tucson. Festival goers should plan their trip to Arizona in April or May, as this largely festival season. If your main desire to avoid the tourist crowds, however, plan your visit anywhere between early May and late October.
