Saguaro in July: what the park service says

July is monsoon time at Saguaro. The park service says the rains come mostly in the afternoons over the mountains and send water down the drainages, so washes and canyons can flash flood; stay out of canyons when rain is forecast, and climb up if caught. Mid-summer is also when saguaro fruit ripens, food and moisture for wildlife in a lean season.
