Best Time to Visit Guangzhou
Autumn especially late September to early December is recommended as the best time to visit the city.
A yearly average temperature of 21 - 29 C (70 - 84 F) makes it a wonderful destination for travel. However, there will be drizzles from time to time in March and April which may spoil your plan.
