The South West has a Mediterranean climate, with dry summers and wet winters. [2] There is about 900 mm of precipitation per year, with most between May and September. [3] Mean maximum daily temperatures range from 16 °C in July to 34 °C in February.
The ecoregion is bounded by the drier Carnarvon xeric shrublands to the north, and the Western Australian Mulga shrublands to the northeast. Mediterranean-climate ecoregions lie to the east and south – the Coolgardie woodlands to the east, the Esperance mallee to the southeast, and the Southwest Australia woodlands to the southwest.
Average precipitation in the southwest and southeast Australia is projected to decline during this time, while regions such as the northwest may experience increases in rainfall. Climate change is affecting the continent's environment and ecosystems. Australia is vulnerable to the effects of global warming projected for the next 50 to 100 years ...
Western Australia occupies nearly one third of the Australian continent.Due to the size and the isolation of the state, considerable emphasis has been made of these features; it is the second largest administrative territory in the world, after Yakutia in Russia, despite the fact that Australia is only the sixth largest country in the world by area, and no other regional administrative ...
The Coolgardie woodlands is an ecoregion in southern Western Australia. The predominant vegetation is woodlands and mallee scrub. The ecoregion is a transitional zone between the Mediterranean-climate forests, woodlands, and shrublands of Southwest Australia and the deserts and dry scrublands of the Australian interior.

The Swan Coastal Plain in Western Australia is the geographic feature which contains the Swan River as it travels west to the Indian Ocean.The coastal plain continues well beyond the boundaries of the Swan River and its tributaries, as a geological and biological zone, one of Western Australia's Interim Biogeographic Regionalisation for Australia regions.
Climate map of Australia. By far the largest part of Australia is arid or semi-arid. A total of 18% of Australia's mainland consists of named deserts, [20] while additional areas are considered to have a desert climate based on low rainfall and high temperature. Only the south-east and south-west corners have a temperate climate and moderately ...
