Nanning Weather

Nanning has a subtropical monsoon climate. Summers are quite long and hot, lasting from May to September; winters from late December to February are not particularly cold compared with China’s northern cities; spring and fall are generally mild with occasional variable temperatures. It is humid year-round, while in spring, it has some extremely humid days. Rainfall is abundant yet sunshine is ample. 
 1. Located in southern China at a low latitude, Nanning experiences above-freezing temperatures year-round, generally ranging from 3 to 37 degrees Celsius (37-99 degrees Fahrenheit).

2. Overall, the temperature difference between day and night is not particularly large, typically ranging from 6 to 8°C (11-14°F). In summer, especially on cloudy or rainy days, thick cloud cover acts as an insulator, so the daily temperature range is relatively small. However, in spring, autumn, and winter, when skies are clear, the daily temperature range can be quite large, hovering between 10 and 15°C (18-27°F). 
 July and August are the hottest months of the year. 

This is because Nanning lies near the Tropic of Cancer, so during July and August, it receives the strongest solar radiation, leading to a significant increase in accumulated heat. Consequently, temperatures rise noticeably. 

In this period, daily high temperatures frequently exceed 35 degrees Celsius (95 degrees Fahrenheit), especially between 14:00 and 16:00. Extreme heat can reach 40 degrees Celsius (104 degrees Fahrenheit). What’s worse, due to high humidity levels, sweat evaporates very slowly, so even in the shade, people continue to sweat profusely. 
 January is the coldest month in Nanning, with daytime highs ranging from 13 to 22°C (55-72°F). However, when a cold front sweeps through, daytime highs can drop as low as 4 to 7°C (39-45°F). Although temperatures don’t fall below zero, the damp air and cold wind would make one feel bone-chilling cold, a challenge for new-comers.
 Nanning’s average annual rainfall is approximately 1,300 mm. The rainy season runs from April to September, with rainfall accounting for 70% to 85% of the annual total. June through August is the peak rainfall period, with monthly rainfall exceeding 200 mm. 

Why is Nanning’s rainfall abundant? Influenced by the southeast and southwest monsoons, large amounts of water vapor from the Sea bring abundant precipitation to Nanning. Additionally, as Nanning is surrounded by mountains on three sides, the uplift of warm, moist air creates relatively gentle rainfall. Convective showers are also frequent. They usually come and go very quickly and only over a small area, but the rain intensity is pretty high.  

The dry season ranges from October to March, with the average precipitation of 35-72 mm monthly. 
 Nanning is the area affected by typhoons, particularly in July and August, when one or two typhoons may even make direct landfall. These usually bring prolonged, heavy downpours, with hourly rainfall reaching 60-80 mm. Other extreme weather events may also occur, including thunderstorms, hail, and gusty winds with force 6-8. Consequently, there is a risk of urban flooding and flash floods.
 Generally, the air of Nanning remains pretty humid throughout the year, with the average humidity level of 74%-82%. Autumn and winter are relatively less humid. 

The most humid period runs from February to April, which is known as “Huinantian” in Chinese. During the transition from winter to spring, as cold air from the north and warm air from the south converge in Nanning, humidity increases sharply; this leads to near-saturated air humidity, to the extent that moisture seeps through walls and clothes are impossible to dry out naturally. This unique weather condition usually lasts for about 3-5 days, and in severe cases can last more than a week. Therefore, it is very important to have a few extra sets of clothes on hand.
 Nanning has an average annual sunshine duration of about 1,800 hours, with the highest sunshine duration occurring in summer. In July, sunshine duration reaches as high as 308 hours, and ultraviolet intensity is very high, with an index exceeding 11. 

Winter and early spring have the shortest duration of sunshine, because of frequent gray days. From January through March, monthly total sunshine hours range from 123 to 186 hours. Also due to overcast skies and thick cloud cover, ultraviolet radiation is significantly reduced, with the UV index ranging from 7 to 9. 
 The best times to visit Nanning are from late October to December from autumn to early winter. 

During this time, Nanning’s climate is at its most pleasant of the year. The temperature is comfortable, neither too cold nor too hot, with daytime highs generally ranging from 17 to 24 degrees Celsius (62-75 degrees Fahrenheit). It is also the dry season, with limited rainfall and the lowest humidity levels of the year. The sunshine feels warm and comfortable on your skin, and you don’t need to put on heavy sun protection items.

November and December are months when temperatures drop rapidly in most parts of China, but in Nanning, thanks to its pleasant temperatures, many seasonal flowers are in bloom, such as chrysanthemums, plums, and osmanthus. Additionally, late December is the best time to view the metasequoias in Nanning, when their colors are at their most vibrant. At the same time, the trees in the city remain lush and green, giving visitors the feeling that spring and autumn overlap here.

Aside from the weather, there are no public holidays during this period, so visitor numbers are relatively low, making it a low season for tourism, ideal for price-conscious travelers.

  Average Monthly Precipitation: 125-216 mm
 Rainy Days: 8-13 days per month 

 Weather Overview: In summer, daytime highs range from 25-33°C (77-91°F), with extreme peak temperatures reaching 40°C (104°F). Nights are cooler, with lows of 23-26°C (73-79°F). Influenced by monsoon winds, summer receives most of the annual precipitation, which can easily lead to flooding. Frequent rainfall and plenty of moisture make the weather even more humid, which makes one feel stifling and unbearable. 

 Why Is Nanning’s Summer So Hot? 
Even though Nanning has a very high vegetation coverage rate, which can relieve the heat a bit, it can still be considered one of the hottest cities in China. Geographically, the city is located in a basin surrounded by mountains on three sides, causing hot air to linger and accumulate. Coupled with abundant moisture, this makes it more difficult for the heat to dissipate, resulting in a high number of hot days and heat lasting for long periods. What’s more, in recent years, due to global warming and the intensification of the urban heat island effect, summer temperatures have shown a trend of increasing year by year. 

 Clothes: Breathable and quick-dry T-shirts, shorts, skirts, light sun-protective jackets, sandals, and light sneakers. 

 Travel Recommendations and Tips:
1. As midday hours feel unbearably oppressive, visitors are highly advised to stay indoors with air-conditioning, such as the Nanning Museum and the Anthropology Museum of Guangxi. 
2. If you are traveling with children, water parks are also a good option, offering a wide variety of recreational activities. 
3. July and August are the summer holidays in China, when schools are out, so family tours and study trips are extremely popular, making it peak season when scenic spots are crowded and travel costs soar. What travelers should also avoid is the May Day holiday in early May, which is even more crowded and expensive than July and August.
