Why does it seem to get colder just before the sun comes up?

Answer 1

Basically it usually gets colder all night long. At night the Earth loses heat into space from the dark areas. The coldest time then is just before the Sun rises and starts to heat everything back up.

Answer 2

After the sun goes down the earth begins to lose it heat. The sun is radiational heating, meaning that it heats object and the objects heat the air. The sun does very little for heating the air directly. During the night the objects (buildings, grounds etc...) radiate that heat back into the atmosphere. On clear nights, the heat escapes further into the atmosphere and therefore it tends to be cooler on clear nights. By morning, before the sun rises, a lot of the radational heat has already escaped and therefore the coolest temperature tends to be just before dawn.

Answer 3

The heat from the earth is radiated into space. At night the heat lost is greater than the heat the earth receive from the sun. It gets colder and colder until the sun heat it.

Answer 4

Coldest part of the morning is within the hour of sunrise and it's when all the heat escapes to space. For the most part the temp slowly goes down after midnight, except for incoming cold fronts from 12-sunrise.

Answer 5

During the night, the earth loses heat...and it continues to all night until the sun rises. Then it begins to get warmer again from the sun.

Answer 6

relies upon on the nighttime. On a cloudy nighttime, the clouds catch the nice and comfortable temperature like an insulating blanket. in the journey that they sparkling before the solar comes up, sure, it ought to proceed to be hotter. In different circumstances, i imagine it is all on your head.
