Nanjing (Nanjing), capital of Jiangsu province, sits on the Yangtze River about 300 km (186 miles) west of Shanghai. Once the capital of six dynasties and the Republic of China, it is now a modern city of 9 million with a 2,500-year-old historic core. The Ming dynasty city wall, a UNESCO-listed imperial tomb, and a Republican-era presidential palace share the landscape with glass skyscrapers and a 10-line metro system. Nanjing’s humid subtropical climate brings furnace-like summers and cold damp winters, but the brief spring and autumn seasons are among the best in eastern China. Below you will find our complete Nanjing travel guide covering weather, attractions, neighborhoods, hotels, and practical tips.
Nanjing Weather at a Glance
Nanjing has a humid subtropical climate (Koppen Cfa) with four distinct seasons. Summers (June-September) are hot and oppressively humid , July averages 32C (90F) with 80% humidity and a heat index that regularly surpasses 40C (104F).

The city receives about 1,100mm (43 inches) of rain annually. Most falls during the plum rain season (mid-June to mid-July), a stretch of near-daily downpours with 80% humidity. Autumn (October-November) is the driest and most comfortable season , October averages 22C (72F) with just 8 rainy days. Spring (March-May) warms quickly but is unpredictable, with 20C swings between day and night in March, making layers essential.

Where Is Nanjing and What Influences Its Weather?
Nanjing sits at 32N latitude on the southern bank of the Yangtze River, roughly 300 km (186 miles) inland from the East China Sea. At 15 meters (50 feet) above sea level, the city occupies the Yangtze floodplain with Purple Mountain (448 meters/1,470 feet) rising to the east. The inland location means no moderating ocean breezes , summer heat builds and winter cold settles in without the buffering effect of coastal waters.
The East Asian monsoon drives Nanjing’s seasonal extremes. In summer, the monsoon pushes hot, moisture-laden air from the South China Sea inland, producing the infamous plum rains and 32C+ temperatures. In winter, the Siberian High sends cold, dry air masses across eastern China, dropping temperatures near freezing. Spring and autumn are transitional periods when competing air masses create the pleasant, settled weather that makes these the prime tourist seasons.
