What time of day is the hottest?

It should be 1- 2 pm. At noon, although the sun shines brightly and the sunlight energy is the highest, the temperature is not the highest. At this time, the energy received by the ground is greater than the energy lost, so the temperature continues to rise. When it reaches 1-2, the energy received by the ground is almost equal to the energy lost, and the temperature does not rise any more. After 2 o'clock, the lost energy is greater than the received energy, and the temperature begins to drop.
