When is the hottest time of the day?

Generally, the highest temperature in a day occurs around 2 pm.

at 12 noon, the sun's radiation is the strongest. The sun shines vertically on the ground, which heats it up. The heat absorbed by the ground is released to dry the air, so it will take some time to raise the temperature.

it was not until two or three o'clock in the afternoon that the ground temperature rose to the highest, and the temperature was the highest. At this time, although the sun was setting in the west, the altitude angle was still very large, and the heat stored on the ground was still greater than the heat released, which made the temperature continue to rise, and the local surface heat broke even, and the ground temperature reached its peak. After that, the heat released from the ground was greater than the stored heat, which reduced the ground temperature.

whether the weather is hot or cold mainly depends on the atmospheric temperature, and the main factor that affects the atmospheric temperature is the heat given to the atmosphere by the sun. But direct sunlight is not the main reason for the temperature rise.

air can only absorb about 14% of the heat from direct sunlight, while about 43% of the heat is absorbed by the ground. When the ground absorbs the heat of the sun, it is conducted into the air through radiation, convection and other forms, which is the direct cause of the temperature rise.
