Rain season
Chengdu is one of China's cloudiest cities — the Sichuan Basin traps moisture and the city averages only about 1,200 sunshine hours per year. The wet season (May–September) brings frequent rain, mostly moderate rather than extreme. Annual rainfall is around 900mm. Persistent overcast and drizzle define the city's character; heavy convective storms develop in warm summer afternoons.
