Planning a trip to Nanjing? Understanding the city's climate is key to packing smart and making the most of your visit. As one of China's historical capitals, Nanjing experiences four distinct seasons, each offering a different face of the city—from plum blossoms in spring to golden ginkgo leaves in autumn.
Here is a practical, season-by-season breakdown of Nanjing's weather, what to expect, and how to plan accordingly.
Nanjing at a Glance: A Subtropical Monsoon Climate
Nanjing sits in the Yangtze River Delta and enjoys a humid subtropical climate. This means you can expect hot, humid summers and chilly, damp winters. The city is also known for its "furnace" summers—it ranks among the hottest major cities in China—and for significant rainfall throughout the year.
One key thing to know: the weather can change quickly, especially during the transitional seasons. Always check the forecast before you head out for the day.
Spring in Nanjing: Mild, Floral, and Occasionally Rainy
Months: March to May
Spring is one of the most beautiful times to visit Nanjing. Temperatures gradually warm from around 10°C in March to a pleasant 25°C by May. The city bursts into color, most famously with the Nanjing Plum Blossom Festival at Plum Blossom Mountain, which typically peaks in late February and March.
However, spring is also a wet season. April often brings light and persistent drizzle, so pack a compact umbrella and a waterproof jacket. Layering is your best strategy: start with a light sweater in the morning and shed layers by midday.
Packing tips: Light long-sleeved shirts, a medium-weight jacket, comfortable walking shoes, and an umbrella.
Summer: Hot, Humid, and Stormy
Months: June to August
Summer in Nanjing is intense. From late June through July, the city endures the Meiyu (plum rain) season—a period of continuous, heavy rainfall. Temperatures hover around 30°C, but with humidity levels often above 80%, it feels significantly hotter.
Temperatures and humidity reach a peak in July and August. This is the "major heat" period, when the city is often compared to a furnace. Expect daily highs above 35°C, sticky evenings, and frequent afternoon thunderstorms.
If you visit during summer, plan your sightseeing for early mornings or late afternoons. Many travelers use this time to visit indoor attractions, such as the Nanjing Museum, and stay hydrated throughout the day.
Packing tips: Lightweight, breathable clothing (cotton and linen), a wide-brimmed hat, sunscreen, sunglasses, and a portable fan.
Autumn: The Golden Window for Travel
Months: September to November
Autumn is widely considered the best season to visit Nanjing. The harsh summer heat breaks in September, leaving behind crisp, clear days with temperatures ranging from 15°C to 25°C. The humidity drops, making it incredibly comfortable for outdoor exploration.
The city is blanketed in golden colors in late October and November, especially along the famous Winged Sycamore avenues and within the Sun Yat-sen Mausoleum scenic area. The "Stone City" truly shines in fall.
Packing tips: Light layers, a light jacket for cooler evenings, and comfortable walking shoes for long, leisurely explorations.
Winter: Cold, Damp, and Atmospheric
Months: December to February
Winter in Nanjing is colder than many travelers expect. Temperatures average between 0°C and 8°C. While it rarely snows heavily, the air is damp, which makes the cold feel more penetrating—a "wet cold" that goes right through you.
This is the off-season, meaning significantly fewer crowds at major attractions. For a different experience, a wintry visit to the Linggu Temple, where the scenery is stark yet serene, can be rewarding. Indoor activities, like a visit to the Nanjing Massacre Memorial Hall or the Porcelain Tower heritage park, are also popular this season.
Packing tips: A heavy winter coat, thermal layers, a scarf, gloves, and warm socks are essential if you visit around January.

Travel Tips for Any Season
- Rain gear is non-negotiable: Shenzhen-like downpours can occur in any season. A foldable umbrella is your constant companion.
- Book in advance for peak seasons: Spring (around Qingming holiday in April) and National Day (October 1st week) are extremely busy. Book accommodation and train tickets well ahead.
- Air quality: Like many large Chinese cities, air quality can vary. Check an air quality index app before planning strenuous outdoor activities.
- Currency and payments: While contactless payments (Alipay and WeChat Pay) are ubiquitous, keep some cash on hand for smaller vendors and street stalls.
