Visiting Nanjing in September
September feels like early autumn
September is warm and often humid in Nanjing, but it's more comfortable than August. Highs reach 29°C, and rain falls on about 10 days. You'll get some sunny spells, though showers can interrupt a long day outdoors.
It's a good month for the city's outdoor sights, including the Ming Xiaoling Mausoleum and the tree-lined paths around Xuanwu Lake. Keep indoor stops such as the Nanjing Museum in mind for rainy afternoons. The heat can still feel sticky, so avoid packing too many exposed, uphill walks into the middle of the day.
Festivals and crowds
The Mid-Autumn Festival sometimes falls in September, though its date changes each year. Families gather, and you'll spot mooncakes, round pastries traditionally shared at the festival. If it overlaps with your visit, expect more people travelling around China.
If you hate crowds, September is usually calmer than October, when China's National Day holiday brings a major travel rush. It's also outside the peak summer holiday period, so stays can be less costly than in summer or October. Prices still vary, especially around the Mid-Autumn break.
Make the most of your visit
Travelling with kids? A gentler outing around Xuanwu Lake can work better than a long climb at Zhongshan.
For a practical route, take the metro to the Sun Yat-sen Mausoleum area, then allow time for the walk and its many steps. After rain, the paths can be slippery, so don't rush the climb. If showers arrive, head back towards the city for Nanjing duck blood vermicelli soup, a local noodle soup often served hot. September's mix of warm afternoons and rainy spells makes flexible plans more useful than trying to fit every sight into one day.
