What are the most comfortable times to visit Tucson?

The most comfortable times to visit Tucson are in May and April before summer begins, and in September and October when it’s coming to a close. In late April, May, and early June, the giant saguaro cacti flower, making the already beautiful landscape even more picturesque. The rainiest and hottest months in Tucson are July and August, when daytime temperatures often exceed 100°F. The desert does get chilly when the sun goes down, so bring some layers for late nights around the firepit.
