When does minimum temperature typically occur during a 24-hour period?

Minimum temperature during a 24-hour period typically occurs about one hour before sunrise due to how Earth's atmosphere cools overnight. During the night, without the sun's heating, the ground loses heat through radiation, causing the temperature to drop. As the night progresses, the temperature continues to decrease until early morning, shortly before the sun rises.

At this point, the loss of heat is at its peak, leading to the lowest temperature of the day being recorded just before dawn. After sunrise, the sun begins to warm the surface and temperatures generally start to rise.

Midnight often experiences a slight increase in temperatures due to atmospheric data and other influencing factors, and the temperature at noon is typically at its highest due to the most significant solar heating. Considering these dynamics, the choice of minimum temperature occurring about an hour before sunrise aligns with atmospheric behavior and temperature trends observed throughout a 24-hour cycle.
