Australia Weather by Month

Australia is the world’s sixth-largest country, covering 7.692 million square kilometers, and is the only country that is also a continent. It is located in the Southern Hemisphere, bordered by the Indian Ocean to the west and the Pacific Ocean to the east. Due to its vast size and geographical diversity, Australia encompasses various landscapes, including tropical rainforests, vast deserts, rugged mountain ranges, fertile plains, and long coastlines.

The country is often divided into several key geographical regions: the coastal areas, the Great Dividing Range along the east coast, the arid and semi-arid Outback covering much of the interior, and the tropical north. Australia’s climate varies significantly across these regions, ranging from tropical in the north, temperate in the south, and desert-like conditions in the interior. The seasons are reversed from those in the Northern Hemisphere, with summer from December to February and winter from June to August.
