This article provides an in-depth overview of Guangzhou's weather throughout the year, including temperature ranges, precipitation levels, and the best times to visit.

Overview of Guangzhou's Climate

Guangzhou experiences a humid subtropical climate, characterized by hot, humid summers and mild, dry winters. The monsoon season brings heavy rainfall, while the rest of the year remains relatively dry. The city’s climate can be broken down into four distinct seasons: spring, summer, autumn, and winter.

1. Spring (March to May)
   Spring in Guangzhou is a transition period from the cool, dry winter to the hot, humid summer. Temperatures gradually rise from an average of 15°C (59°F) in March to about 25°C (77°F) by May. The humidity levels also increase, especially in late April and May, making the weather feel warmer than it actually is.
   This season is known for its blooming flowers and lush green landscapes, making it a popular time for outdoor activities like hiking and visiting parks. However, spring can also be rainy, particularly in May, when the city experiences the start of the monsoon season. Average monthly rainfall during this period ranges from 100mm (3.9 inches) in March to 230mm (9 inches) in May. Thunderstorms are common during this time.

2. Summer (June to August)
   Summer in Guangzhou is hot and humid, with temperatures often soaring above 30°C (86°F). The humidity can make it feel even hotter, sometimes pushing the heat index to over 40°C (104°F). This is the peak of the monsoon season, with June and July being the wettest months. Average monthly rainfall can exceed 280mm (11 inches), and typhoons are a common threat, especially in July and August.
   Despite the heat and rain, summer is a lively season in Guangzhou. The city hosts several festivals and events, and the riverside areas are popular for evening strolls to escape the heat. The rainfall, though heavy at times, usually comes in short bursts, allowing for periods of dry weather during the day.
   Visitors should be prepared for sudden downpours and carry umbrellas or raincoats when exploring the city during this time.

3. Autumn (September to November)
   Autumn is considered the best season to visit Guangzhou. The weather is warm but not overly hot, with temperatures ranging from 25°C (77°F) in September to 20°C (68°F) in November. The humidity levels drop significantly, making the air feel more comfortable compared to the summer months.
   Rainfall decreases as well, with October and November being the driest months of the year. The average monthly rainfall during autumn is around 60mm (2.4 inches). This season is perfect for outdoor activities, sightseeing, and enjoying Guangzhou's rich cultural heritage.
   Many tourists choose to visit during the famous Canton Fair, held in October and November, which attracts business professionals from around the world.

4. Winter (December to February)
   Winter in Guangzhou is mild and dry, with temperatures ranging from 10°C (50°F) to 20°C (68°F). While it can get chilly at night, especially in January, the daytime temperatures are usually pleasant. Guangzhou rarely experiences freezing temperatures, and snowfall is extremely uncommon.
   The dry conditions make winter an ideal time for outdoor activities, and the city's parks and gardens are often full of life. However, the air can feel dry, and visitors should stay hydrated and use moisturizers to prevent skin dryness.
   Chinese New Year, which usually falls in late January or early February, is a significant event during this season. The city is adorned with decorations, and there are numerous cultural activities, parades, and fireworks displays.
