Guangzhou belongs to the south of the Tropic of Cancer and belongs to the tropical region. But at the junction of subtropics and tropics, the climate is more subtropical.

1, tropical region:

It is a technical term in meteorology, which refers to the zone between the Tropic of Cancer, located on both sides of the equator and between 23 26' south latitude, accounting for 39.8% of the total area of the world. It is characterized by high temperature all the year round with little change.

2. Tropical location:

The zone between the Tropic of Cancer and the Tropic of Cancer is located on both sides of the equator, in the tropical zone between 23 26' south latitude and 23 26' north latitude, accounting for 39.8% of the global total area. On the tropic of cancer, the height of the sun in this area is very high all year round. In the vast area between the Tropic of Cancer, there is direct sunlight once a year, and in other tropical areas, there are direct sunlight twice a year. Moreover, the height of the sun is very high at noon all the year round, with little change. Therefore, this area can get strong sunshine all year round, and the climate is hot, which is called the tropics. On the equator, the length of day and night is equal throughout the year. From the equator to the Tropic of Cancer, the length of day and night changes gradually. On the regression line, the difference between the longest day and the shortest day is 2 hours and 50 minutes. It can be seen that in tropical areas, the latitude difference of astronomical phenomena is very small. Tropical areas are characterized by high temperature all year round, with a small range, only relatively hot seasons and cool seasons or rainy and dry seasons.
