Why is the area with the highest temperature in the world in July not the place where the equator passes?

In July, the highest temperature in the world was in the desert area near the Tropic of Cancer. The major reasons for this are the following

(1) In July, the noon sun near the Tropic of Cancer is higher than the equator, with strong solar radiation and high temperature;

(2) In rainy weather near the equator, the atmosphere has a strong weakening effect on solar radiation, and less solar radiation reaches the ground. The desert area near the Tropic of Cancer is sunny, and the atmosphere has a relatively weak weakening effect on solar radiation. There is more solar radiation reaching the ground and the temperature is higher.

(3) The ocean area near the equator is large, and the temperature is not easy to rise due to the influence of the ocean. The mainland near the Tropic of Cancer is large and the temperature is easy to rise.
