Extended data

Shanghai has a mild and humid climate, with shorter spring and autumn and longer winter and summer.

March to May is the best tourist season in full bloom in spring. What needs special reminder is that the rainy season is from mid-June to early July, both sunny and rainy. The rainfall of more than 20 days accounts for about 1/4 of the whole year, so it is not suitable to travel during this period.

From the end of August to the middle of September, typhoons are frequent, and there are often downpours. You must take a sun umbrella to Shanghai during these two periods. Fortunately, the climate is hot at this time, and sunny days can also be used as sun protection.
