Climate, Weather in Western Australia
Western Australia climate is one of the most diverse in the country, divided into three main climatic zones: tropical, semi-arid and Mediterranean.

Western Australia weather
*The north is tropical, characterized by a sunny dry season (April to September) and a wet season (October to March) with its humidity, heavy rains and thunderstorms. The dry season has ideal temperatures, with hot days and mild evenings.
*The central part of the state falls within the semi-arid zone and consists mostly of deserts.
*Mediterranean climate characterizes the south where the summers are warm and dry and the winters mild and wet.
Rain
Average annual rainfall varies from 300 millimetres (12 in) at the edge of the Wheatbelt region, but in the months of November to March evaporation exceeds rainfall, and it is generally very dry. The central four-fifths of the state is desert and is lightly inhabited with the only significant activity being mining. Annual rainfall averages 200-250 millimetres. An exception to this is the northern tropical regions. The Kimberley has an extremely hot monsoonal climate with average annual rainfall ranging from 500 to 1,500 millimetres, but there is a very long almost rainless season from April to November.

Perth is best to visit during spring (September-November) and autumn (March-May) with dry and sunny conditions and not too hot.
