May brings significant rainfall to Sichuan, particularly in southwestern regions like Panzhihua, marking the onset of the rainy season. 

Eastern Sichuan’ climate is slightly rainy this month. Take the example of Chengdu: the average precipitation is about 79 mm from 15 days; yet this won't disrupt your outdoor plans. Precipitation this month is featured in primarily light rain, followed by occasional thunderstorms. In addition, it is unevenly distributed: daily precipitation can range from under 2 mm to as much as 20 mm. Therefore, we highly recommend that you check the forecast in advance and schedule indoor activities like visiting the Sanxingdui Museum on heavily rainy days. Alternatively, carrying a raincoat adds flexibility and comfort for outdoor activities on lightly rainy days, such as watching pandas at the Chengdu Giant Panda Base.

Northwestern Sichuan in May also receives moderate rainfall. But you don’t have to worry about it affecting your enjoyment too much because it is usually light showers. After the rain in Jiuzhaigou, the air here is refreshingly crisp, and the scenery appears even more vibrant. Just slip on a waterproof jacket, and the misty atmosphere of the post-rain landscape won't disappoint you.

Daytime hours in Sichuan extend steadily throughout May, with up to 14 hours of daylight. This gives travelers ample time to explore the bustling streets, relatively peaceful cultural attractions and vibrant natural landscape. For instance, in Chengdu, you can spend a day wandering through Jinli Street or Chunxi Road, or immersing yourself in the long history at Du Fu Thatched Cottage and the Sanxingdui Museum at leisure. Even if you head to surrounding places like Mount Qingcheng or Dujiangyan, there’s no need rush thanks to the late sunset.

With an average of 10 hours of sunshine per day, the landscapes look even more charming and it’s easier to take beautiful photos. However, UV radiation is quite strong this month, so sun protection is essential.

Bottom Clothing: Light jeans or shorts work well. Female travelers can also wear long dresses for a stylish yet comfortable outfit. For tours in northwestern Sichuan, hiking pants are more practical. 

Footwear:
A pair of comfortable sneakers is always a safe choice, especially for long walks or hikes.

Frequent light showers mean that rain gear is necessary: a raincoat is more practical than an umbrella for mountain treks.
