During the rainy season, between October and March, average temperatures are around 30°C and the humidity is very high.

In the famous seaside town of Broome, the wettest months are between January and March, where the average annual rainfall is around 600 mm. The influence of the ocean means that the temperatures along the coast suffer less marked variations between day and night, compared to what happens in the interior of Western Australia.
