What month is the rainy season in Guangzhou?

April to June or so. Guangzhou is located at the southernmost tip of China. Under the influence of monsoon, warm and humid air in the South China Sea and the Pacific Ocean will flow northward in summer. In early summer, warm and humid air will be blocked by cold air and terrain, causing the air to rise and form clouds. This monsoon circulation pattern began to form from April to June, bringing the rainy season to Guangzhou. So the rainy season in Guangzhou is from April to June.
