(1) As the transition from summer to autumn takes place in September, the weather of Changsha in this month gets a little cooler. In general, the temperature sees a gradual decrease. In the first half of the month, the city still experiences high temperature of 39 degrees Celsius (102 degrees Fahrenheit), making people feel extremely hot outdoors. After mid-September, cold air causes obvious temperature drops, and the high temperature can fall to 25°C (77°F), bringing some coolness and making it ideal to travel. The low temperature ranges from 29 to 18°C (84 to 64°F), and the temperature between day and night is relatively large after mid-September.
(2) Changsha gets low rainfall of about 84 mm in about 9 days, and the intensity of precipitation is not high. Showers happen frequently on days with rainfall, and will lead to a-few-degree decrease in temperature and make the weather cooler and more comfortable, especially in the first half of the month. In very rare cases, heavy rain falls down all of a sudden and lasts for a short period of time.
(3) Fog sometimes forms at dawn in Changsha in September, which is caused by the occasional temperature drops together and the high humidity, and visibility in the early morning will be affected. The fog usually disperses as the temperature rises.
In September, Changsha has shorter days from 12 hours and 40 minutes to 11 hours and 55 minutes. Meanwhile, the sunrise time is later from 06:10 to 06:22 day after day, and the sunset time is earlier from 18:50 to 18:17. If you want to wander along the Xiangjiang river and enjoy the sunset view, you’re suggested to get to the bank earlier than 18:30 in the first half of the month, and no later than 18:10 in the second half.
You need to further notice that the maximum UV index can be quite high at 10, and sunshine radiation is strong on sunny days, making sunburn prevention essential.
Note: You can bring more sets of warm and cool clothes, to cope with the change between sunny and rainy weather and also large temperature difference between day and night.
Clothes: On sunny days with 30°C-and-above (86°F) heat, recommended clothes are T-shirts, shorts, thin long pants, skirts, and dresses. On cooler rainy or overcast days, and also at cooler dawn and dusk to night, wear long-sleeved shirts and sweatpants.
Shoes: Breathable and non-slippery flats or sneakers.
1. Enjoy Drifting in Liuyang City
In view that the weather in the first half of September is still hot, you can add water activities into your travel plan in the afternoon on sunny days. The river channel in the Daweishan Mountain in Liuyang is relatively smooth, so you can enjoy your drifting in a more relaxing way. Plus, if enough drifting rafts gather together, people can sprinkle cool and clear river water over each other, having a lot of fun.
Tips: A waterproof bag is a must during drifting.
2. Immerse Yourself in Changsha Locals’ Life
As summer ends in mid-September, a stroll along the Xiangjiang River becomes a nice activity to experience the leisure life of local people. The stunning sunset, the sky with afterglow, and the illuminated buildings on the other bank are all so impressive. Besides, in the soft breeze at dusk, nothing beats sitting on a lounge chair, drink tea or bear by the river, and enjoy wonderful music shows presented by live-house bands.
3. Take Sightseeing Train to Visit around Orange Isle
As the must-go attraction in Changsha, the Orange Isle is not only famous for the great statue of Mao Zedong, but also boasts a large coverage of lush vegetable. You’re recommended to take the colorful sightseeing train to travel around the isle, and view rows of golden-rain trees with pink capsules. Just choose the trees as your photo background, and capture such beautiful autumn scenery with your camera.
