Madera Canyon Road climbs from the Sonoran Desert floor in Green Valley at around 2,700 feet where the temperature in summer may be from 85° to 105°F (30° to 40°C) to 5,500 feet where the temperature will be some 20°F cooler. Monsoon rain storms begin in early July and continue through August into September. The storms do not occur every day and usually the cells are small and highly localized, but when they are over you, prepare for hail and a brief downpour with falling temperatures. Dry washes fill with rushing water and Madera Creek can flood so be careful. In winter, expect snow above 5,000 feet and temperatures near freezing in the canyon. For all these climate conditions, be prepared with adequate foot gear and layered clothing. |
