Christmas in Chengdu usually brings cool, damp weather that feels colder than the numbers on the thermometer. Daytime temperatures hover around 11–12°C (52–54°F), while nights often drop close to 5°C (41°F).
Snow almost never shows up, but the air stays heavy with moisture, and the city spends most days under a gray sky.
December barely sees any rainfall, which actually makes it the driest month of the year. Still, the lack of sunshine mixed with high humidity can leave you feeling chilled, especially since most homes and smaller hotels don’t use central heating.
The climate adds a unique wintery vibe that changes how you experience the city’s streets, food, and whatever holiday activities you might find.
If you know what to expect—temperature, humidity, and air quality—you’ll plan your trip a lot better. It’s also worth thinking about how December stacks up against other months, what clothes will keep you comfortable, and which seasonal activities let you make the most of Chengdu’s winter mood.
Typical Weather in Chengdu at Christmas
Late December in Chengdu means cool, damp conditions, short days, and clouds that rarely seem to lift. Temperatures stay mild compared to northern China, but the mix of high humidity and little sun makes it feel colder than you might expect.
Average Temperatures in December
You’ll usually see daytime highs around 8–11 °C (47–52 °F) near Christmas. At night, lows fall to 2–5 °C (36–41 °F), and some mornings might flirt with freezing.
The city’s basin traps moisture and cool air, so the chill cuts deeper than the thermometer says. While heavy snow almost never shows up in December, frost can appear in the outskirts and nearby mountains.
Here’s a quick look at late December averages:
| Date | Avg High | Avg Low |
|---|---|---|
| Dec 24 | 9 °C / 48 °F | 2 °C / 36 °F |
| Dec 25 | 9 °C / 48 °F | 2 °C / 36 °F |
| Dec 31 | 8 °C / 47 °F | 1–2 °C / 35 °F |
Dressing in layers helps, with a warm coat, sweater, and gloves for evenings. Indoor heating is pretty limited, so you’ll probably feel chilly even when you’re inside.
Rainfall and Precipitation Patterns
December stands out as the driest month in Chengdu. Rainfall barely reaches 5–10 mm for the entire month, so it’s nothing compared to the summer.
Showers are usually light and don’t happen often, so you probably won’t need to worry about heavy rain at Christmas.
Even so, the damp air and humidity keep everything feeling moist. Streets and buildings often seem wet, even without much rain.
Snow’s rare in the city, but you might spot it in the surrounding mountains, especially up at Xiling Snow Mountain.
You won’t need an umbrella every day, but a small travel umbrella or waterproof jacket might come in handy.
Sunshine Hours and Daylight Duration
Winter in Chengdu is famous for its overcast skies. Around Christmas, you’ll only get 1–2 hours of sunshine per day.
The sky sticks to a dull gray, and clear days don’t really happen.
Daylight is short too. The sun rises at about 7:30 AM and sets by 6:00 PM, which gives you around 10.5 hours of daylight. With all the cloud cover, the city feels dim most of the day.
If you’re planning outdoor activities, do them earlier to catch what light you can. Even during the day, expect a muted, shadowy vibe instead of bright sun.
Humidity and Air Quality During December
Chengdu’s December weather is damp and cool, with a lot of moisture in the air. Haze often blurs the view, and the cold always seems to bite deeper than the numbers say. Air quality can be a concern thanks to seasonal smog.
Relative Humidity Levels
Humidity stays very high in December, often averaging around 90%. This heavy moisture makes the cold feel sharper, even if temperatures don’t look extreme.
Rain is minimal, just about 11 mm over 3 days, so the dampness mostly comes from the basin trapping moisture. Weak winds don’t help dry things out.
Indoor spaces often feel chilly, especially since many homes and smaller hotels skip central heating. Pack warm clothes that work in damp conditions, like layered sweaters and water-resistant jackets.
Air Pollution and Smog Considerations
Air quality tends to drop in December. The Sichuan Basin traps both humidity and pollution, so haze and smog happen a lot.
On calm days, with barely any wind, particles just hang around.
Pollution levels climb because of more coal used for heating and less air movement. You’ll probably notice poor visibility, with the skyline hidden behind a stubborn gray layer.
If you’re sensitive to air quality, check the daily AQI before heading out. Carry a mask rated for PM2.5 to help cut down on exposure.
When the air clears, things improve, but the damp cold still hangs around, making the air feel heavier than it does in drier northern cities.
Chengdu’s Humid Subtropical Climate Explained
Chengdu sits in the Sichuan Basin, which gives the city a humid subtropical climate (Cwa). Winters are mild, summers get hot, and rain peaks in the middle of summer.
You experience all four distinct seasons, but the mountains around the basin trap moisture, so the air feels damp for much of the year.
Winter Weather Characteristics
In winter, temperatures stay pretty mild compared to the north. December and January usually bring average highs around 10–11°C (50–52°F) and lows near 3–5°C (37–41°F).
Extreme cold doesn’t happen often, though some nights can dip below freezing.
Rainfall is lowest in winter. December averages only 7 mm (0.28 in) of precipitation, and January looks much the same.
Snow is possible but light, usually totaling less than 10 mm (0.4 in).
Humidity stays moderate, and although the sky’s often overcast, heavy storms don’t really show up. Winds are weak, so the cold doesn’t sting as much as it does in drier northern places.
Winter feels damp more than harsh, so expect cool, gray days. Usually, a light jacket or some layers will keep you comfortable.
Seasonal Climate Variations
Chengdu’s weather shifts clearly with the seasons. Spring (March–May) warms up fast, with highs climbing from 19°C (66°F) in March to 28°C (82°F) in May.
Rain starts picking up, hinting at the monsoon’s approach.
Summer (June–August) gets hot and sticky. Highs reach 30–31°C (86–88°F), and July–August see the most rain, sometimes up to 218 mm (8.6 in) in a month. Showers happen often, and humidity stays above 70%.
Autumn (September–November) cools down and dries up. September still brings some rain, but by November, totals drop below 15 mm (0.6 in). Temperatures fall from 26°C (79°F) in September to 16°C (61°F) in November.
This seasonal rhythm—wet summers, dry winters—really defines Chengdu’s humid subtropical climate and shapes the kind of weather you’ll get all year.
How December Weather Compares to Other Months
December in Chengdu feels cooler and less rainy than most other times of the year. The month stands out for its damp chill, gray skies, and barely any rainfall compared to the wetter spring and summer.
Temperature Trends Across the Year
December temperatures in Chengdu usually average 8–12°C (47–53°F) during the day and 1–5°C (34–41°F) at night. That’s colder than autumn months like October, which stay closer to 15–20°C (59–68°F).
January gets even colder, often dipping near freezing at night. On the other hand, July and August are the hottest, with highs of 30–33°C (86–91°F) and warm nights around 23°C (73°F).
Spring and autumn bring milder weather. In April, daytime highs often reach 20–24°C (68–75°F), while October averages 18–22°C (64–72°F).
| Month | Avg High | Avg Low |

| December | 11°C (52°F) | 5°C (41°F) |
December lands on the colder side of Chengdu’s climate, but temperatures inside the city rarely fall below freezing.
Rainfall Patterns by Month
Chengdu’s rainfall follows a seasonal cycle. December is the driest month with totals usually under 10 mm and just a few days of light rain. The air feels damp, but real precipitation is very limited.
July and August are the wettest, each bringing over 200 mm of rain. Showers happen a lot and can be heavy, making summer both humid and unpredictable.
Spring months like March and April bring moderate rain, often between 40–70 mm, while autumn months like October see rainfall drop again to about 40 mm.
| Month | Avg Rainfall |
|---|---|
| January | ~10 mm |
| April | ~60 mm |
| July | ~220 mm |
| October | ~40 mm |
| December | ~5 mm |
If you visit in December, you’ll dodge the summer downpours, but the sky tends to stay gray with very little sun. This combo makes the city feel colder than the numbers alone would have you believe.
What to Pack and Wear in Chengdu at Christmas
Around Christmas, Chengdu’s temperatures usually sit between 3°C (37°F) at night and about 11°C (52°F) during the day. The damp air makes the cold feel stronger, so bringing the right clothes will help you stay warm and comfortable while exploring.
Layering and Clothing Recommendations
You’ll want layers you can add or remove as needed. Start with a thermal or cotton base layer to hold in warmth.
Add a thick sweater or fleece as a middle layer, then top it off with a down jacket or insulated coat. This setup works for daytime walks and chilly evenings.
For your legs, bring thick pants or lined trousers. Jeans by themselves might not cut it in the damp, so maybe wear thermal leggings underneath.
Shoes should be closed-toe and insulated, with soles that grip wet pavement.
Accessories really help in Chengdu’s December weather. A warm hat, scarf, and gloves will keep you comfortable, especially in the mornings and after sunset.
If you plan to head up into the mountains, these extras become even more important.
Tips for Staying Comfortable Outdoors
Chengdu gets a lot of cloudy or foggy days in December, and the sun barely comes out. You’ll want to carry a light rain jacket or umbrella—light drizzle happens pretty often, even if heavy rain almost never does.
Waterproof outerwear really helps block out the damp air.
Since most public places don’t have central heating, make sure you dress warmly before heading out. Restaurants or shops indoors can actually feel colder than you expect.
Walking around is honestly the best way to soak in Chengdu’s parks and neighborhoods. Wear comfortable shoes with soft soles if you plan to be out for a while.
The dry winter air can still sneak up on you, so keep a reusable water bottle handy.
Seasonal Activities and Attractions in December
December in Chengdu feels cool and damp, with shorter days and a quieter vibe. You’ll find fewer crowds at cultural sites, and you can check out nearby mountains—sometimes there’s even a light dusting of snow.
Warming up indoors with local food or catching a performance is a nice way to experience the city’s traditions.
Outdoor Experiences Near Chengdu
The Chengdu Research Base of Giant Panda Breeding is a must-see, especially since pandas get more active in cooler weather. If you go in the morning, you’ll dodge the crowds and spot the animals being playful.
People’s Park and Huanhuaxi Park stay open all winter. They’re great for short strolls, but the paths can get damp. Bring waterproof shoes if you’re walking for a while.
You can take a day trip to Dujiangyan and see the ancient irrigation system. Winter mist often drifts over the rivers, giving the place a really calm feeling. Buses and trains make it pretty easy to get there in less than an hour.
Visiting Mount Qingcheng in Winter
Mount Qingcheng sits about an hour from Chengdu, and it’s one of China’s main Taoist mountains. December gets colder up there than in the city, and you might spot frost or light snow on the higher trails.
The main paths stay open. Some stone steps get slippery, so sturdy shoes are a must.
Cable cars keep running in winter, which is perfect if you don’t want to climb all the way up.
You can visit ancient Taoist temples like Jianfu Palace, and they look amazing against a winter backdrop. The mountain feels much quieter in December, so you get more space to enjoy the scenery and explore cultural sites without big crowds.
Indoor Activities and Cultural Highlights
When the weather gets damp, Chengdu’s tea houses offer a cozy escape. Shu Feng Yun Tea House, for example, serves tea alongside Sichuan opera, and you might catch that famous face-changing show.
They even have heated seats, so it feels pretty comfortable on those cold evenings.
If you’re in the mood for something a bit more educational, the Jinsha Site Museum and the Sichuan Museum let you explore local history without braving the rain.
Both museums sit in central locations, and you can hop on the metro to reach them easily.
Food really shines in December.
Hot pot and mala tang seem to hit the spot in winter, since that spicy broth warms you right up.
Local restaurants usually stay busy in the evenings, though outside the holidays, you probably won’t have to wait long for a table.
