Why is it so hot?

The sun moves from the southern hemisphere to the northern hemisphere.

The southern hemisphere began to get cold and the northern hemisphere began to get hot. Because we are in the northern hemisphere.

So winter is the coldest time.

Summer is the hottest time.

If we are in the southern hemisphere, summer is the coldest.

Winter is the hottest.

There is another special case.

You live in

Within the north-south polar line

therefore

You will be cold all year round.

If you live in the Tropic of Cancer

Near the equator

You will be hot all year round.
