How It WasThe Sonoran Desert, including Southern Arizona, has a climate with two distinct precipitation seasons. There are longer, low-intensity rains during the winter months (December/January) while the summer monsoons (typically July-September) feature violent pop-up thunderstorms that can drop torrential rains in a short span of time. These rainy seasons allow for a broad diversity of flora and fauna to exist in this otherwise semi-arid environment. How It Is NowDeserts, like the Sonoran Desert of the Pimería Alta, appear timeless. We still have winter rains and summer monsoons. Winter often brings snow to the mountain tops and frosts to the lower elevations. Spring brings the glorious blooms from cactus, trees, and wildflowers. Yet there are changes occurring to the weather and climate of southern Arizona. |
