Summers are hot, although temperatures vary greatly between the desert floor and the Chisos Mountains. The rainy season extends from mid-June to October with locally heavy thunderstorms and some flash flooding. However, the water recedes rapidly and the rainy season can be a delightful time to visit the desert. Winters are generally mild, although periods of cold weather (including light snow) are possible. Winter visitors must prepare for a variety of conditions.
