What Makes Kunming's Weather So Unusual?

Kunming has a subtropical highland climate and four features make it different from almost any other place in China.

• Cold, sunny wintwe and warm cloudy rainy summers, instead of freezing cold or extremely hot.
• A large difference between day and night temperatures, so mornings can be chilly while afternoons are nice and warm.
• Two different parts of the year: dry and clear from November to April, wet and cloudy from June to September.
• Around 2,200 hours of sunlight each year which is a lot, for China.

The result is easy to understand: no month is really bad to visit. You don't often face 30°C heat or freezing nights and the main thing to watch for is rain, not temperature.

What Should You Pack for Kunming's Climate?

Layering is the game in Kunming because the difference between a chilly morning and a warm afternoon is very big.

• A light insulated jacket or fleece needed for mornings and evenings and especially for winter.
• A breathable long-sleeve top that you can take off by midday, when the sun is doing most of the heating.
• Comfortable walking shoes, because Dianchi Green Lake and the stone terraces of Shilin require a lot of walking.
• A compact rain. A sturdy umbrella.
• Sunglasses, because at this altitude, the UV is stronger than the temperature shows.
