The best time to go to Aztec is during the spring (late March to May) and autumn (September to October) months when the weather is most pleasant for outdoor activities.During springtime, the temperatures are mild, typically ranging from 15°C to 25°C, making it ideal for exploring the Aztec Ruins National Monument without the heat of summer. The desert landscape also begins to bloom with wildflowers, adding to the scenery.Autumn offers similar comfortable temperatures, usually between 10°C and 20°C, and the skies are often clear and sunny. This season is superb for hiking, cycling, and enjoying the natural beauty of the surrounding area. The changing colours of the cottonwood trees along the Animas River are also a highlight.While summer (June to August) can be hot, with temperatures often exceeding 30°C, it's still a good time to visit if you plan your outdoor activities for the cooler mornings or evenings.
