What is the season on the south part of earth ?

It is summer on the south part of earth.

The Southern Hemisphere is the half sphere of Earth which is south of the equator. It contains all or parts of five continents Antarctica, Australia, about 90% of South America, the southern third of Africa, and several southern islands off the continental mainland of Asia), four oceans Indian, South Atlantic, Southern, and South Pacific and most of the Pacific Islands in Oceania. Its surface is 80.9% water, compared with 60.7% water in the case of the Northern Hemisphere, and it contains 32.7% of Earth's land.

Hope this helps. :)
