Why the coldest part of a night is most of the time at dawn? How do we explain this signifiant temperature drop?
EDIT: I get answers telling that’s because sun has been out the longest when sun rises again. Indeed it makes sense that the night will continuously go coolest, but the weird thing is: There is a real, proper drop on the thermometer every morning at the dawn, event if we stayed at 5°c all night long, at the very first lights, it will drop to 4°c and then go back to 5°c a moment later (actually happened again this morning).
The reason of this radical drop is my question.
Thank you guys it’s amazing to have questions and to be able to ask it to you. Love this sub.

The temperature drops at a steady pace while the sun is down, just before dawn is coldest because the sun has been down the longest.
It often feels colder, because psychologically we expect it to be warmer when it is light out, and the same temperature will seem colder as the sky lightens.
