Best Time To Visit Shanghai For Tourists

The best time to visit Shanghai for tourists is the fall, roughly late September to early November. Shanghai sits on the Yangtze River Delta and runs a humid subtropical climate with four genuinely distinct seasons: a damp, raw winter, a fast-warming spring, a hot and sodden summer, and an autumn that is the clear pick of the year. Summer is what catches people out. July and August average highs of 33 and 32 degrees Celsius, overnight lows sit around 26, and August alone drops 215 mm of rain. Winter swings the other way, with January averaging a high of 8 degrees and a low just under 2. This is a working port city before it is anything else: Shanghai has moved more containers than anywhere on earth for sixteen straight years, clearing 55.06 million TEU in 2025. It is also home to about 25 million people. Both facts show up in the queues.

Average weather in Shanghai

Shanghai collects roughly 1,165 mm of rain a year and close to half of it falls in June, July and August. The table below is the month-by-month baseline.

Month	Avg high (°C)	Avg low (°C)	Rainfall (mm)
January	8.3	1.6	75
February	10.3	3.3	60
March	14.4	7.2	95
April	20.4	12.5	75
May	25.6	17.8	84.5
June	28.3	22	180
July	32.8	26.2	145
August	32.3	26	215
September	28.4	21.8	85
October	23.3	16	55
November	17.4	10	50
December	11	3.7	45

Two patterns matter. The rain is lopsided: August alone brings more than October, November and December combined. And the temperature spread is wide, about 25 degrees between the January high and the July high, so a February trip and a July trip need entirely different luggage. Humidity stays between roughly 68 and 78 percent all year, which is why the summer figures feel hotter than they read and the winter figures feel colder. Shanghai gets around 1,775 hours of sun a year, and the sunniest months are July and August at about six hours a day, which is thin compensation for everything else those months bring.

When is the best time to visit Shanghai?

Late September to early November. Daytime highs run from 28 degrees down to a comfortable 17, the summer humidity has broken, and October and November are the two driest months of the warm half of the year at 55 mm and 50 mm. Mid-March to late April is the credible second choice, warm and green before the plum rains arrive. Everything else is a trade-off, which is fine as long as you make it on purpose.

Spring weather in Shanghai

Spring runs March to May and it climbs fast. March averages a high of 14 degrees Celsius; by May the average high is 26. Rain is moderate, 95 mm in March easing to 75 in April, and it arrives as showers rather than the sustained sheets of summer. This is blossom season. Cherry, peach and magnolia come through in late March and early April, and Gucun Park, Century Park and the Shanghai Botanical Garden are where the city goes to look at them. The catch is variability: a spring week here can hand you 25 degrees and sun, then 12 degrees and drizzle two days later. Pack layers and a light waterproof and do not trust a five-day forecast.

Summer weather in Shanghai

Summer is June to early September and it is a season to plan around rather than for. June opens the plum rains, the meiyu, when a front stalls over the Yangtze delta and delivers 180 mm across the month, mostly as days of heavy humidity broken by downpours. July and August are the hot months, and because the overnight lows hold at about 26 degrees the city never really cools off. August is the wettest month of the year at 215 mm. Typhoons can reach Shanghai from June to early November, with the risk concentrated in late summer, and a serious one will close the airports and erase a day or two of whatever you had booked. If you travel in these months, anchor the itinerary on indoor things, the museums, the Bund after dark, a Huangpu River cruise in the evening, and keep the outdoor half movable.

Shanghai weather in the fall

Fall is the reason to come. September still carries summer heat at an average high of 28 degrees, but by October the highs settle to 23 and the rain drops to 55 mm, with only November and December drier. November averages 17 degrees by day and 10 at night, crisp rather than cold. The foliage peaks later than most travelers expect: late November into early December is when the ginkgo, Chinese tallow, trident maple and callery pear turn, and Zhongshan Park and the Shanghai Botanical Garden are the dependable spots. This is also hairy crab season. The Yangcheng Lake mitten crabs run from September through November and are at their best in October and November when the roe is full, and it is the one food event the city organizes itself around. Nanjing Road, the Bund and the Oriental Pearl Tower are all better in this season for the simple reason that the crowds thin once the National Day holiday week ends on October 7, and hotel rates follow them down.

On the ground

Autumn is the window worth booking a private Shanghai tour for. The foliage, the hairy crab restaurants and the thinner post-Golden-Week crowds all land inside the same six weeks, and a guided day means you spend them looking at the city instead of working out the metro and the queue at the Oriental Pearl. It is the best-value guided stretch of the year here.

Winter weather in Shanghai

Winter is December to February, and the problem with it is not the temperature but the damp. January is the coldest month at an average high of 8 degrees Celsius and a low just under 2, with December and February two or three degrees warmer by day. Those numbers look mild written down, and they are, but Shanghai sits south of the line that divides China’s municipal heating, so buildings have no district heating the way Beijing’s do and the cold gets indoors with you. Snow is rare and never guaranteed; when it comes it is between late December and early February and it does not lie for long. The upside is real. Winter is the driest run of the year at 45 to 75 mm a month, the queues at Yu Garden and along the Bund are short, and hotel rates are the lowest they get. Bring a proper coat and do not assume inside will be warmer than outside.

Worst time to visit Shanghai

Three periods to avoid, for three different reasons:

• National Day holiday week, October 1 to 7. The whole country travels at once. Attractions, trains and flights run at capacity and prices climb to meet them. The weather is excellent, which is exactly the problem.
• Chinese New Year, late January or February depending on the lunar calendar. In 2027 it falls on February 6, with the public holiday expected to run February 5 to 11, confirmed by the State Council late the previous year. Transport books out weeks ahead and many family-run restaurants and shops close for the week.
• July and August. Hottest, wettest, most humid, inside typhoon season, and carrying the domestic school holidays on top.

December and January are not on that list. They are cold and damp, but they are also quiet and cheap, and a winter visit to Shanghai is a fair trade if you would rather have the Bund to yourself than have it warm. The dates that genuinely hurt are the two holiday weeks, and those are the ones to book around.
