Since Western Australia spans the continent from the north to the south, the climate is very diverse, with the north coast experiencing a tropical climate, while the south coast has a temperate climate and the central region experiences desert conditions.

In the north, the temperature is usually around 30 °C to 35 °C year round, with the temperature rising to above 40 °C some days. The months of October and November are especially humid and can cause it to feel much warmer than it actually is. The months of November to April bring with them the wet season, which makes travelling to some areas nearly impossible.

Inland areas in the Outback, can have summer temperatures of almost 50 °C, so the best time to travel these regions is during the winter months of April to October, when the heat is not as severe.

The southern part of Western Australia, where Perth is located, has warm summers and cool winters. The best time to visit is during spring (September to November) or autumn (March to May), when the weather is dry and sunny, but not too hot.
