Weather in September

September welcomes the beautiful autumn season with comfortable weather in Arizona. The average high temperatures are in the warm range of 73°F (22.8°C) to 100°F (37.8°C), while the nights are temperate in the average low temperature zone of 42°F (5.6°C) to 76°F (24.4°C).
Moisture from the Gulf of California occasionally reaches the interior of Arizona to bring moderate rainfall in the range of 1" (25mm) to 2" (51mm) in the north and the south. The skies remain clear, with at least 25 sunny days amid a low degree of humidity. The early fall season sees a significant drop in temperatures and thunderstorms compared to the summer.
Wildlife is active during dawn and dusk when the conditions are comfortable to forage for food. Many tourists prefer to visit the national parks and forests during the fall season due to moderate conditions. The northern hilly areas are a favorite destination for many with cooler temperatures and are the first places in the state that see leaves changing colors in fall. The hunting season is in full swing in September in Arizona.
