Average weather, temperature, rainfall, sunshine hours

Guiyang's climate is
temperate humid, with quite cold winters and warm, rainy summers.
The city is the capital of the province of Guizhou and is located in south-western China, at 26 degrees north latitude, and at an altitude between 1,050 and 1,250 meters (3,445 and 4,100 feet).
The rains are abundant from May to September, while in winter they are light but frequent.
The sun is rarely seen, in fact southwest China is the least sunny area of the country and one of the least sunny in the world.
In
winter there are mild periods, but also quite cold periods, in which fog forms. In addition, there can sometimes be very cold periods, with snow and frost.
Due to the altitude,
summer is not as hot as in other areas of central-southern China, however, during heatwaves, the temperature can reach around 35 °C (95 °F).
The city can be hit by
typhoons, the tropical cyclones of Southeast Asia, even though it is located quite far from the coast, which is the area most at risk. Typhoons typically occur in this area from June to October or early November.
