Guangzhou enjoys a subtropical climate, making it relatively hot and humid in summer and pleasantly mild in winter. Summer-like weather extends well beyond the three months from June to August. From May to October, temperatures in this bustling international hub often exceed the daily average of 30°C (86°F), so if you’re prone to wilting at the first sign of humidity, aim to visit Guangzhou in late autumn or through winter when temperatures are much more manageable, ranging between 10°C (50°F) and 21°C (70°F).
Guangzhou’s location on the Tropic of Cancer means there is a rainy season. If you plan to travel any time between July and September, expect to use your wet weather gear as this is the time that rainfall peaks. While this climate has its drawbacks for those who aren’t fans of the heat, there is one major benefit. Guangzhou earned its nickname ‘Huacheng’ or flower city for the year-round proliferation of beautiful blooms.
