Australia is a continent that experiences a variety of climates due to its size. The temperature can range from below zero in the Snowy Mountains in southern Australia to extreme heat in the Kimberley region in the north-west of the continent. Due to the size of the continent, there is not one single seasonal calendar for the entire continent. Instead there are six climatic zones and this translates as two main seasonal patterns. There is a Summer / Autumn / Winter / Spring pattern in the Temperate zone, also affecting the Desert and the Grassland climatic zones and, a Wet / Dry pattern in the tropical north which includes the Equatorial, Tropical and sub-tropical zones. Depending upon where you are each Month, the season will vary on whether the weather is defined by the Temperate zone seasons or the tropical seasons.
