We are moving into spring! Due to the Earth’s axial tilt, seasons in the South Hemisphere are opposite to North Hemisphere thus winter is finished. Meteorologists often define winter as the three calendar months with the lowest average temperatures. For the Southern Hemisphere, it is June, July, and August.
The word hemisphere means half of a sphere, and because the earth is kind of spherical, half of the earth is a hemisphere. The Southern Hemisphere is the southern half of the Earth. It begins at the equator and continues south into the South Pole in the middle of Antarctica. It includes Southern Africa and South America, Australia and NZ.
In comparison to the Northern Hemisphere, the Southern Hemisphere has fewer land masses and more water. To put it into perspective, only 10% of human population live in the Southern Hemisphere! Also, due to the large presence of water, climate is more mild overall in the Southern Hemisphere.
Random fact: The first Winter Olympics were held in Chamonix, France, in 1924. No country in the Southern Hemisphere has hosted, or even been an applicant to host, the Winter Olympics. I guess it would be the hottest winter olympics ever.
