Because the inclination of the sun's rays are different in every hour. At 12 noon, the sun's rays direct hit the the earth at a small distance while for exmple at 6pm the hit of the rays of the sun is much farther than if it is 12 noon.

There is normally a daily rise and fall of temperature at the earth's surface(except probably at the poles)-known as diurnal variation of temperature.This is owing to the incident solar radiation varying in intensity at a place during the course of the day.The reception of solar radiation is maximum at mid-day with maximum absorption. At night, the radiation from the sun is cut-off with the result that the place radiates back the heat towards the outer space,getting thereby cooled.
The variation of temperature is generally more over land than over sea.
Cloudiness, wind direction and altitude also affect this diurnal variation of temperature over a place.Nature of soil also affects the temperature to some extent.
At higher latitude, the diurnal variation of temperature is less.

How about the accumulation of Solar energy over the course of the day; absorbed in the air, the water and solid object. As night falls that heat is radiated at differing rated by different materials.

The temperature changes do to how much sun wind or rain an area has. fog and clouds also effect it

The amount of radiation from the sun reaching the earth increases from morning to mid-afternoon, then decreases toward evening.
