Flowering trees and cacti are not as sensitive to rainfall and temperature and usually have a good bloom each year. The saguaro cactus bloom peaks in May and June. Summer heat reaches its peak in June and July. Throughout the summer, almost all animal activity occurs in early morning, late evening or at night. July and August also bring our summer monsoon season.
Rainfall can be very intense.
Quiet time, cooling temperatures make for good hiking conditions, especially in the mountains. Pace yourself and rest often. There is no water available at picnic areas or along most trails. Beware of painful encounters with cacti and other prickly plants. Be especially careful near cholla cactus spines that, with just the slightest touch, can become embedded in your skin.
