December is one of the drier months in Chengdu, though light rain can still occur. The city receives an average of 50 to 80 mm (2 to 3 inches) of rainfall during this month. Rain is typically light to moderate, but the frequency of rain showers can contribute to a sense of dampness in the air.

Humidity levels in December are relatively high, often ranging between 70% and 80%.

Fog is a common phenomenon in Chengdu during December. The combination of cool temperatures, high humidity, and stagnant air can lead to foggy mornings. This can occasionally affect visibility, so if you’re driving or navigating the city, be prepared for reduced visibility conditions.

5. What to Wear

Given the mild but cool temperatures, it’s best to wear warm clothing in layers. A medium-weight coat or jacket should suffice, but be sure to include warm sweaters and thermal wear if you’re sensitive to the cold. Rain gear, such as an umbrella or a waterproof jacket, is also recommended to handle any unexpected rain showers.

6. Activities and Attractions

December in Chengdu is a great time to enjoy indoor attractions or visit hot springs. The city’s famous Sichuan cuisine is a perfect way to warm up, with many restaurants offering spicy dishes that are ideal for the winter season. Additionally, exploring Chengdu’s historical sites, like the Wuhou Shrine and Jinli Ancient Street, can be pleasant with fewer tourists around.

If you’re interested in nature, consider visiting nearby areas like the Chengdu Research Base of Giant Panda Breeding, where you can see the pandas in a cozy, winter setting.
