Air quality in China varies by city, season and the weather on the day. Northern cities such as Beijing have the clearest worry in the cold months, when haze can settle, while highland and southern cities are gentler. The practical answer is to pick your month with care, check the reading each morning and keep an indoor plan ready.
If someone in your group has a sensitive chest, this is a fair thing to plan around. It is not a reason to cancel China.
When is haze most likely?
Think in seasons, because the air follows the weather.
- Winter in the north: cold, still days can trap haze. Beijing winters are very dry[1], and cities in the north that heat their buildings in winter feel it more.
- Spring in the north: wind can bring dust, so mornings can look yellow-grey even when it is not cold.
- Summer: rain and warm air usually clear the sky, though humid days feel heavy.
- Autumn: usually the calmest season for views in the north, but Golden Week crowds are the bigger problem.
Beijing averages about -3.7 C in January and about 26 C in July[2]. That swing is a reminder to pack for weather first, and check the air second. Our guide to dressing for China’s weather from the tropics covers clothing.
How do you check the air each morning?
Use the weather app that came with your phone, or a Chinese app your hotel recommends. Google services, including Search and Maps, are blocked in mainland China[3], so do not rely on a Google weather tile that will not load.
Look at the reading before you plan the day. If it is poor, move your outdoor sights to another day and use the swap list below.
What if the air is poor on the day?
Keep the day full, but move it indoors.
- Swap a long walk on the wall or a park for a museum.
- Swap a lake or hill for a covered market or food street.
- Take a taxi instead of walking between sights.
A short outdoor stop is fine for most people if they feel well. Seniors and children should skip long queues outside and sit in an indoor cafe between visits.
Which seasons suit sensitive travellers?
Autumn and spring have their charms, but check dates against holidays. Read our guide to China in April for spring, and China in December before you plan a winter city break.
Highland Kunming is nicknamed the City of Eternal Spring for its mild weather[4], and Guilin and Yangshuo are low, green and quiet. If Mum or Dad finds cold or haze tiring, those are good places to start.
