When you’re planning a trip to Shanghai, you really have to think about the weather. This city experiences four distinct seasons, and each one changes how you’ll see its streets, parks, and skyline.
The best time to visit Shanghai is during spring (March to May) and autumn (September to November). The weather feels mild, the skies usually look clearer, and it’s just easier to enjoy the city outdoors.
You’ll spot big differences from season to season. Summers get hot and sticky, with heavy humidity, while winters feel damp and can be pretty chilly.
Spring and autumn, though, are perfect for strolling along the Bund, checking out gardens, or joining local festivals without having to worry about extreme heat or cold.
It helps to know what each season brings. When you get a sense of Shanghai’s climate—average temperatures, rainfall, and all that—it’s way easier to pack right, pick your travel dates, and actually enjoy the city’s best sights.
Overview of Shanghai Weather
Shanghai has a humid subtropical climate because it sits on the coast. You’ll see four real seasons, with summers that feel hot and damp, winters that are chilly and damp, and those pleasant in-between stretches in spring and autumn.
Climate Characteristics
Shanghai’s climate is humid and subtropical, which means long, muggy summers and short, cool winters. The city’s spot on China’s eastern coast lets both continental and ocean air shape the weather.
Rain falls pretty often, especially from late spring through early autumn. Typhoons can hit between July and September, bringing heavy rain and strong winds.
Humidity sticks around all year. In the summer, it often climbs above 80%, making the heat feel even heavier. In winter, the damp air and low temps combine, so it feels colder than the numbers say.
Air quality changes with the seasons. You might notice smog in the colder months, especially when coal heating picks up in nearby areas. Still, sea breezes help clear the air more than in inland cities.
Seasonal Weather Patterns
Spring (March–May) brings mild temps, blooming flowers, and moderate rainfall. You’ll get some of the best weather for being outside.
Summer (June–August) arrives hot, humid, and rainy. Afternoon thunderstorms pop up a lot, and July and August can feel relentless. Typhoons sometimes hit, but they don’t usually last long.
Autumn (September–November) is the most stable. Days are sunny, dry, and comfortable, with lower humidity. Sightseeing’s at its best here.
Winter (December–February) is cold and damp. Snow rarely falls, but you might get frost or icy winds from the north. Indoor heating isn’t as strong as in colder places, so you could notice the chill more inside.
Temperature Ranges
Shanghai’s temperatures swing a lot through the year. Winters typically hit around 3–9°C (37–48°F), while summers often rise to 27–35°C (81–95°F).
Spring and autumn feel moderate. In April, highs average 18–23°C (64–73°F), and October brings highs around 20–25°C (68–77°F).
Rainfall averages about 1,100–1,400 mm annually, with June often the wettest. Autumn gets the most sunshine, so you’ll see clearer skies than in the muggy summer.
You can see why spring and autumn are the most comfortable times to be in Shanghai.
Best Seasons to Visit Shanghai
Some times of year just make exploring Shanghai easier. Mild temps and less rain mean you can get outside more, and these seasons line up with some of the city’s best events and activities.
Spring: March to May
Spring in Shanghai slowly warms up, with temperatures between 10°C and 25°C (50°F–77°F). Early March stays cool, but by May, you’ll want lighter clothes. You’ll get occasional rain, especially around the Qingming Festival in early April.
This is a great season to explore outdoors. Yu Garden bursts with spring flowers, and the French Concession gets leafy and green. Parks like Century Park become hotspots for cherry blossoms and magnolias.
Crowds aren’t too bad, though public holidays can make attractions busy. Bring a light jacket, an umbrella, and comfortable shoes. If you’re heading out of town, Suzhou and Hangzhou look amazing with their tea fields and blooming gardens.
Spring just balances good weather, pretty scenery, and manageable crowds.
Autumn: September to November
Autumn is probably Shanghai’s most comfortable season. Temperatures range from 15°C to 28°C (59°F–82°F), with lower humidity and clearer skies than in summer. Rain falls less often, and the air feels crisp but not cold.
This is the time for walking tours and riverfront views. The Bund looks stunning under blue skies, and cycling in the French Concession is a breeze with cool air. Seasonal foods like hairy crabs pop up everywhere.
The only real downside is the National Day holiday in early October, when crowds fill up attractions and trains. If you skip that week, you’ll enjoy steady weather and great views from places like Shanghai Tower.
Autumn just gives you the most reliable conditions for seeing the city and its nearby cultural spots.

Rainfall and Humidity Levels
Rain falls steadily in Shanghai, but how much you get depends on the season. Spring brings light to moderate showers that freshen up the city. By June and July, the East Asian monsoon dumps heavy rain and humidity spikes. Those months can feel sticky, with lots of downpours.
August stays humid, but rain starts to ease off as you get into September. Autumn, especially October, is drier and the skies clear up. Winters don’t bring much rain, but you’ll still see a few drizzly days.
Summer humidity can climb over 80%, so the heat hits harder. Spring and autumn usually feel more pleasant, with moderate humidity levels.
Dry and Wet Periods
The wettest stretch in Shanghai runs from June to September. Typhoons and summer storms can show up, dropping heavy rain, but these showers often clear out quickly. Be ready for sudden rain during this time.
October through December usually bring the driest months. Rain falls less often, and you’ll get clearer skies and good visibility. January and February stay drier than summer, though the cold air makes things feel damp.
Spring, especially March to May, gives you a good mix. There’s some rain, but it’s not as intense as summer, and the mild temps make it easy to get outside.
Visiting Shanghai’s Iconic Attractions by Weather
Weather really affects how much you’ll enjoy Shanghai’s tallest landmarks. Clear skies and comfortable temps matter most, since the main draw is the view from those observation decks.
Best Weather for Oriental Pearl TV Tower
At the Oriental Pearl TV Tower, you can see the Bund, Huangpu River, and Pudong skyline. To catch those views, you’ll want days with low humidity and clear air. Spring (March–May) and autumn (September–November) usually give you the best mix of mild temps and good visibility.
Summer often brings haze, thick humidity, and rain, so the view from the glass decks isn’t as sharp. Winter feels cold, but after a cold front, you might get crisp air and great views.
Try to visit in late morning or early afternoon when the sky’s brightest. Average spring temps: 15–22°C (59–72°F). Average autumn temps: 17–23°C (63–73°F). Those are perfect for walking around the area and checking out the river.
If you want to walk on the glass-bottomed walkway, you’ll need dry weather. Rain can make the glass slick and mess up the view below.
Ideal Conditions for Shanghai Tower
Shanghai Tower, the country’s tallest building, has an observation deck up on the 118th floor. The higher you go, the more the weather matters. Clear, calm days mean you can see all the way across the city—and sometimes even farther if the air’s really clean.
Spring and autumn still work best for visiting. These months are comfortable, and you’re less likely to get heavy rain or typhoon winds. Spring averages: 13–20°C (55–68°F). Autumn averages: 16–22°C (61–72°F).
Summer brings thunderstorms and fast-moving clouds that can block the view. High winds up top sometimes shut down parts of the deck. In winter, it’s colder, but drier air after rain can clear out pollution and improve visibility.
Pick days with steady weather and check the air quality before you go. On a clear day, you’ll get some of the best photos in all of Shanghai from up here.
Travel Tips for Different Weather Conditions
Shanghai’s weather jumps from damp winters to muggy summers, with those nice, mild months in between. If you know what to expect, you can pack right, stay comfy, and dodge any surprises from rain or wild temperature swings.
Packing Essentials by Season
In spring (March–May), temps stay mild but rain’s pretty common. Bring a light waterproof jacket, an umbrella, and layers like sweaters or cardigans for chilly mornings and nights. Good walking shoes that can handle wet streets help a lot.
During summer (June–August), Shanghai gets hot and humid, with highs over 30°C (86°F). Stick to lightweight, breathable clothes. Don’t forget a hat, sunglasses, and sunscreen—the sun can be strong. A portable fan or cooling towel isn’t a bad idea either, especially when the humidity ramps up.
In autumn (September–November), the weather is dry and comfy. Short sleeves work during the day, but you’ll want a light jacket for the evenings. Packing’s easy since the weather’s pretty steady.
Winter (December–February) is cold and damp, and temps often hover near freezing. Bring a warm coat, gloves, and a scarf. Heating inside can be weak, so layering helps. Waterproof shoes are smart for rainy days, because the streets can stay slick.
Outdoor and Indoor Activity Planning
Spring feels like the perfect time for outdoor sightseeing. You might find yourself wandering the Bund, checking out Yu Garden, or just soaking in the cherry blossoms in local parks. Rain showers pop up pretty often, so it’s smart to keep your plans loose and have a few indoor ideas in your back pocket.
Summer in Shanghai? The heat and humidity can really wear you out. If you want to be outside, try going early in the morning or waiting until the sun starts to set. When the afternoon hits, most people duck into air-conditioned museums, shopping malls, or aquariums to cool off and escape the muggy weather.
Autumn usually brings the best weather for outdoor adventures. You can stroll through historic streets, hop on a river cruise, or plan a day trip to a nearby water town. Rain isn’t much of a problem, so you’ll likely get through a whole day outside with no big interruptions.
Winter’s damp chill drives most people indoors. The Shanghai Museum, art galleries, and cozy tea houses turn into popular escapes. If you’re up for it, outdoor walks are still doable, but you’ll want to keep them short if it’s windy or raining.
Other Considerations for Planning Your Visit
Weather shapes more than just your comfort in Shanghai. It also changes how crowded the city feels and when big cultural events happen, which can really affect your trip.
Crowd Levels and Tourist Seasons
Shanghai gets the busiest in spring (March–May) and autumn (September–November). Mild temperatures pull in lots of international visitors, so you’ll probably run into higher hotel prices and longer lines at spots like the Bund or Yu Garden.
Summer brings another rush of travelers, especially families on school break. June sometimes gets rainy, but July and August fill up thanks to vacation schedules and big draws like Shanghai Disneyland. If you’d rather avoid crowds, winter (December–February) is the quietest stretch, though it can get pretty chilly.
China’s Golden Week holidays in early October and around Lunar New Year always mean heavy domestic travel. Trains and flights sell out fast, and the famous landmarks get packed. If your trip falls during these holidays, planning far ahead makes things much easier.
Here’s a simple breakdown:
| Season | Crowd Level | Typical Costs | Notes |
|---|---|---|---|
| Spring | High | Higher | Pleasant weather, flowers in bloom |
| Summer | High | Moderate | Hot, humid, family travel peak |
| Autumn | High | Higher | Cool, clear, Golden Week crowds |
| Winter | Low | Lower | Cold, fewer tourists, cheaper stays |
Local Events Influenced by Weather
Shanghai’s festivals and seasonal events usually follow the city’s climate. In spring, you’ll spot cherry blossoms at parks like Gucun Forest Park. Mild weather draws people out for outdoor fairs and cultural exhibitions.
Summer gets pretty hot and humid, so most folks prefer evening activities. Night markets, river cruises, and light shows along the Huangpu River all pick up after sunset, when it finally cools off a bit.
In autumn, the city goes all out for the Mid-Autumn Festival. Lantern displays and mooncake traditions pop up everywhere. The crisp, dry air feels perfect for outdoor concerts and food festivals too.
Winter means fewer large outdoor events. Still, you’ll find Christmas markets, indoor exhibitions, and temple fairs during Lunar New Year. These gatherings move indoors or adapt to the chilly weather, but you can feel the season’s influence.
If you pay attention to how weather shapes crowds and activities, you’ll probably pick travel dates that suit your own comfort and interests.
