Which season is the coldest?

Answer 1

basically because the sun is "tilted" away from the sun therefore we don't get much sunlight.

Answer 2

Winter is generally considered the coldest season in many regions around the world. Temperatures drop significantly during winter due to the tilt of the Earth's axis away from the sun, resulting in shorter days and less direct sunlight.

Answer 3

Mid-Winter is the coldest time of the year.

That's January-February in the northern hemisphere,

and July-August in the southern one.
