The best time to visit Tianshui is during the spring (April to May) and autumn (September to October) months.
During these periods, the weather is pleasantly mild, with comfortable temperatures that are ideal for exploring the region's historical sites and natural landscapes. Spring brings blooming flowers, especially around Maijishan Grottoes, making for picturesque scenery. Autumn offers clear skies and comfortable conditions for outdoor activities, without the intense heat of summer or the cold of winter.
For those interested in hiking and outdoor exploration, particularly around the Maijishan Grottoes and the surrounding scenic areas, these seasons provide the most agreeable conditions. The paths are generally dry, and the moderate temperatures make extended walks enjoyable for travellers who appreciate being outdoors.
If your primary interest is visiting the cultural and historical sites, such as the Fuxi Temple, these seasons avoid the peak tourist crowds and extreme weather, allowing for a more relaxed and reflective experience.
