For most travellers, the best time to visit Datong is during the spring (April to May) and autumn (September to October) months. These periods offer the most comfortable weather for exploring the city's historical sites.
During spring, the temperatures are mild and pleasant, typically ranging from 10°C to 20°C. The landscape begins to green, making outdoor excursions, such as a visit to the Yungang Grottoes, particularly enjoyable without the intense heat of summer or the chill of winter. It's a great time for those who prefer to explore at a relaxed pace.
Autumn also provides agreeable conditions, with temperatures similar to spring, usually between 8°C and 18°C. The skies are often clear, offering excellent visibility for sightseeing. This season is ideal for couples interested in photography, as the natural light is often very good, and the cooler air makes extended walks around sites like the Hanging Monastery more comfortable.
While summer (June to August) can be warm, with temperatures sometimes exceeding 30°C, it's still a great option for those who don't mind the heat, especially as many hotels offer air conditioning.
