  • Spring is from September to November.

  • Western Australia is by far the largest state in Australia and as such experiences a very diverse climate. The climatic zones of Western Australia vary from tropical, to semi-arid and Mediterranean in the south. In the north of the state hot monsoonal weather which includes cyclonic rains and thunderstorms is common. The central regions, which are in the semi-arid zone and mostly desert, endure very hot and dry conditions for most of the year with extremely cold night temperatures. The southern regions experience a more temperate climate, especially on the coastal regions. Some meteorologists describe these regions as Mediterranean, with warm and dry summers and mild and wet winters – ideal for wine and crop growing.

    The highest recorded maximum temperature in Western Australia was recorded at Mardie in the Pilbara region on the 19th of February 1998, with 50.5 degrees Celsius.

Here the weather cycle consists of only two distinct seasons, Winter and Summer and major climate events such as cyclones and floods can affect travel arrangements for both those working in the region and those holidaying.

    Wet season in the Kimberley and Pilbara regions usually consist of heavy falls of rain, but in short downpours, usually in the late afternoons and early evenings. Fantastic lightening shows and wonderful sunsets are a natural consequence of this varied climate. Electrical storms are prevalent during the wet season and whilst they can be spectacular to view, caution must be taken to ensure distance between you and lightening.

    As mentioned previously tropical cyclones are a regular occurrence in the Kimberley and Pilbara regions during the wet seasons. Alerts are issued for the varying degrees of warnings.

    Blue Alert signals that a cyclone has formed and is expected to affect the region within a 48 hour period. Precautions should be taken.
    Yellow alert signals that the cyclone is moving closer to the region within a 12 hour period, and residents should take action.
    Red alert signals that a cyclone is imminent with destructive winds and residents are recommended to immediately seek safe shelter.

    The Tropic of Capricorn virtually runs laterally through the centre of the state, effectively dividing the state into two, and south of the Tropic the weather is far more settled and predictable.
