The annual average temperature is between 2 1.5℃ and 22.2℃. In 2024, the average temperature in Guangzhou is between 10℃ and 20℃. In 2023, the average temperature in Guangzhou is between 1.2℃. In June, 2022, the average temperature in Guangzhou was around 12℃, but when it was between 10℃ and 20℃, compared with other regions, such as Jilin and Hohhot, the temperature was not too cold. But you also need to wear some velvet sweaters or thin sweaters to keep warm, so it's not very cold to travel to Guangzhou in January.
