it decreases steadily
The angle of insolation into a surface is largest when the surface directly faces the Sun. That coincides with the temperature rising. So the angle of insolation goes up as the temperature goes up.
Summer
The relationship is that both angles are the same

The angle of insolation is the angle the sun's rays hit a given surface on Earth measured from the horizon up to the position of the sun. The steep angle of the sun at midday allows the maximum amount of infrared to reach you, and you perceive this as heat. In the morning and the evening, the light must pass through a much greater distance of atmosphere, more heat is absorbed in the atmosphere, which never reaches you.
The angle of insolation affects the intensity of insolation directly. In other words, as the angle of insolation increases, so does the intensity of insolation because the Sun is directly overhead at Zenith, giving off direct, or vertical rays. The opposite happens when the angle of insolation decreases, causing a decrease in the intensity of insolation as well.
The angle of insolation into a surface is largest when the surface directly faces the Sun. That coincides with the temperature rising. So the angle of insolation goes up as the temperature goes up.
you can measure the angle of insolation by measuring the angle of the shadows that appear

Directly on the equator.
the 30 degree angle is near the equator and the 90 degree angle is near the trop of Capricorn and cancer
The angle the sun's rays hit a given surface on Earth.And the angle is measured from the horizon up to the position of the sun
