Shanghai has a subtropical monsoon climate with four distinct seasons. The average annual temperature is 17.8 C in 2023.

Spring (March to May)

Spring in Shanghai is warm, with flowers in bloom, making it the best season for tourism. People are stepping out of their homes and strolling through parks, with light jackets becoming the standard attire for outings.

During this time, temperatures often fluctuate between chilly in the early morning and pleasantly warm by the afternoon. The average temperature ranges from around 11 to 21 C. Frequent drizzles are a common sight.

Summer (June to August)

Summer here is extremely hot and humid. The highest temperatures, typically in July and August, frequently soar above 35 C in 2024. Thunderstorms are a regular occurrence in the afternoon, providing a brief respite from the sweltering heat.

To escape the heat, residents and visitors often visit water parks, air-conditioned shopping malls, or cozy cafes.

Notably, from mid-June to early July, Shanghai enters its annual rainy season. Also known as the "plum rain season", this long period of continuous rainy or cloudy weather is not the most favorable time for travel.

Autumn (September to November)

In autumn, the temperature gradually cools down from around 25 C in early fall to about 15 C towards the end. The yellow plane tree leaves and gentle breezes make it an ideal time for outdoor activities like hiking or strolling along the Bund.

Peak typhoon season, generally lasting from late August to mid-September, often brings strong winds and heavy rainfall. If you plan to visit Shanghai during this time, make sure to carry an umbrella that can be used for both rain and sun protection.

Winter (December to February)

Winter is cold and damp. Although the average temperature ranges from 3 to 11 C, the humidity makes it feel much colder. Snowfall is rare, and some years may pass without any snow at all.

The coldest period typically falls between late January and early February, when the piercing north winds make it necessary to wear gloves, scarves, and hats for full protection.
