The climate is variable, with frequent droughts lasting several seasons, thought to be caused in part by the El Niño-Southern Oscillation. Average annual rainfall map of Australia 1 : 8250000 Austrálie H.A. A 2005 study by Australian and American researchers[73] investigated the desertification of the interior, and suggested that one explanation was related to human settlers who arrived about 50,000 years ago. [59][60], The Victorian Alps in the north-east are the coldest part of Victoria. Australia's Lake Eyre region has the lowest annual rainfall. The graphs are produced using daily rainfall data from the Patched Point data set and data from the department's upgraded DPIRD Weather Website . The climate of the coastal strip is influenced by warm ocean waters, keeping the region free from extremes of temperature and providing moisture for rainfall.[26]. [140] Tropical cyclones are known to bring destructive winds, heavy rain with flooding creating storm surges along the coast, causing inundation to low-lying areas. [11], The majority of the state has the arid and semi-arid climates. Earth rainfall climatology Is the study of rainfall, a sub-field of meteorology.Formally, a wider study includes water falling as ice crystals, i.e. Source: Bureau of Meteorology Australian Water … The first half of the 20th century was markedly drier than the second half, with a significant increase in the late 1940s (Murphy and Timbal, 2008). Weather on your smartphone or tablet For iPhone and Android. There is no obvious simple relationship be- droughts are likely to become more frequent, particularly in the south-west, evaporation rates are likely to increase, particularly in the north and east, high-fire-danger weather is likely to increase in the south-east, This page was last edited on 10 December 2020, at 10:24. This agricultural region of Western Australia is in the top nine terrestrial habitats for terrestrial biodiversity, with a higher proportion of endemic species than most other equivalent regions. Snow outside these areas is a major event; it usually occurs in hilly areas of south-western Australia. Comparatively, most inland (non-mountainous) areas south of the tropics have average July minimum between 0 and 6 °C. Seasonal highs and lows can still be considerable. The southern coastal parts of the state have a Mediterranean climate with mild wet winters and hot dry summers. The coldest region is the Snowy Mountains where the snow and frost continues for a long period during the winter months. [98] Temperature differences between winter and summer are minor in the tropical region of Australia. [89] A place inland near Lake Eyre (in South Australia) would only receive 81 mm (3 in) of rain annually. Australia has an annual rainfall variation that is larger than any other continent. The mean data are based on the standard 30-year period 1961-1990. Each place has a total for how many days of wet weather it usually gets a year and for the normal amount of precipitation. The average annual rainfall is 553 mm. The central east area of Queensland, an area the size of Germany and France combined, was under water in 2010–11. Australian rainfall deciles since 1900. June is … Adelaide (46.1 °C on the 12th), Melbourne (45.6 °C on the 13th) and Sydney (45.3 °C on the 14th) all had record-high temperatures during this period, as did many other central district areas in New South Wales, Victoria and South Australia. The observed warming has hastened in recent years. Many of the higher mountains in the territory's south-west are snow-covered for part of the winter. Temperature poster. Home | Privacy & Cookies | Contact | About. The absence of any significant mountain range or area of substantial height above sea level, results in very little rainfall caused by orographic uplift. [when?] Rising levels of salinity and desertification in some areas is ravaging the landscape. [89] The regions between Broome and Exmouth are most prone to cyclones. It ranges from semi-arid and hot in the north-west, to temperate and cool along the coast. The national total rainfall for 2019 was 40% below the 1961–1990 average at 277.6 mm (the 1961–1990 average is 465.2 mm). Sensitivity of the Australian Monsoon to insolation and vegetation: Implications for human impact on continental moisture balance. New Zealand ranked second for average rainfall in depth > mm per year amongst High income OECD countries in 2008. Annual Precipitation Averages for Cities in Australia The tables below give yearly averages for rainfall at large cities across Australia. The average and annual rainfall in 80% of Australia … Tasmania's lowest recorded minimum temperature was −14.2 °C (6.4 °F) on 7 August 2020, at Liawenee.[48]. During the dry season nearly every day is warm and sunny, and afternoon humidity averages around 30%. [131], New projections for Australia's changing climate include:[132], Climatic factors contribute to Australia's high incidence of bushfires, particularly during the summer months. The tropical savannah zone of Northern Australia is warm to hot all year. The state's lowest minimum temperature of −11.7 °C (10.9 °F) was recorded at Omeo on 13 June 1965, and again at Falls Creek on 3 July 1970.[11]. A big part has a hot desert climate with only 200mm (7.8 inch) rainfall per year . Rainfall for 2016 (625mm) was above the long-term average. The average annual temperature is 17.3 °C | … Average minimum temperatures in all seasons are highest in northern Australia and near the coastal areas, and are lowest in the elevated areas of the south-east. 2. [8] The lowest temperature was −14.6 °C (5.7 °F) at Gudgenby on 11 July 1971.[9]. December to February is summer; March to May is autumn; June to August is winter; and September to November is spring. Average temperature has risen about 1°C. The wet season is associated with tropical cyclones and monsoon rains. Victoria's main land feature, the Great Dividing Range, produces a cooler, mountain climate in the centre of the state. The coastal areas are less warm. Because of its elevation (650 m (2,130 ft)) and distance from the coast, the Australian Capital Territory experiences a dry, continental climate (Dsa). Mean monthly and mean annual rainfall grids. Sydney, Australia: Annual Weather Averages. Mean annual rainfall across Australia is shown in Fig. An exception to this is the northern tropical regions. At lower elevations, most inland places south of the tropics have extreme minimum between −3 and −7 °C, and these low temperatures have also occurred in locations within a few kilometres of southern and eastern coasts, such as Sale, Victoria (−5.6 °C), Bega, New South Wales (−8.1 °C), Grove, Tasmania (−7.5 °C) and Taree, New South Wales (−5.0 °C).

The rainfall in Wollongong is significant, with precipitation even during the driest month. A Color Coded Australia Average Annual Climate Precipitation Map, with Yearly Average Inches of Rainfall. However, even in the Stirling Range, snowfalls rarely exceed 5 cm (2 in) and rarely settle for more than one day. Snow at sea level is occasionally recorded on mainland Australia, but is more frequent in Tasmania where snowfalls at sea level can occur during the winter months. Particles are transported by saltation and suspension, causing soil erosion from one place and deposition in another. When blizzards do occur, they can affect the Tasmanian Highlands and, particularly, Mount Wellington, which towers over the Tasmanian capital Hobart. The Kimberley has an extremely hot monsoonal climate with average annual rainfall ranging from 500 to 1,500 mm (20 to 59 in), but there is a very long dry season of 7 months from April to November. Hunt. Modelling persistence in annual Australia point rainfall J. P. Whiting 1, M. F. Lambert 1, and A. V. Metcalfe 2 J. P. Whiting et al. [93] The highest annual rainfall was 12,461.0 millimetres (490.6 in) recorded also at Mount Bellenden Ker in 2000. Occasionally, tropical cyclones can bring heavy rainfall to tropical coastal regions, which is also likely to reach further inland. In Adelaide, rainfall amounts to 530 mm (20.9 in) per year, with a maximum in late autumn and winter. It is Australia's fourth-most populous city, with a population of 2.14 million living in Greater Perth. It is the driest of all the Australian capital cities. Autumn lasts between March and May and experiences changeable weather, where summer weather patterns gradually take on the shape of winter patterns.

The sea in Adelaide is … Canberra Snowy Mountains South West Slopes Southern Tablelands The best month to swim in the sea is in January when the average sea temperature is 23°C (73°F). Victoria's highest recorded daily rainfall was 375 millimetres (14.8 in) at Tanybryn in the Otway Ranges on 22 March 1983.[11]. Victoria has a varied climate despite its small size. List of wettest known tropical cyclones in Australia, "CSIRO report says Australia getting hotter with more to come", "Rainfall and Temperature Records: National", "Climate statistics for Australian locations", "Sydney (Observatory Hill) Climate Statistics", "Summary statistics Alice Springs Airport", "CHAPTER 7: Introduction to the Atmosphere", "Liawenee in Tasmania's Central Highlands breaks record for coldest temperature in island state". Averages are for Sydney Airport, which is 6 miles from Sydney. Overnight minimum temperatures have warmed more rapidly than daytime maximum temperatures. Data for 2017 is not available. Annual rainfall in 2019 was very much below average over much of Australia, although parts of Queensland's northwest and northern tropics were wetter than average. Adelaide generally has mild, wet winters and warm, dry summers. Plan ahead with this information on weather and rainfall in Australia’s capital cities. The original source of this data can be found here . In 1902, the national average rainfall total was 314mm, compared to last year’s 277.6mm. Based on weather reports collected during 1985–2015. South Australian city Adelaide only experiences around 50 days of rainfall per year, while areas more central like Oodnadatta and Coober Petty only experience about 15 days of rainfall per year. The human death toll of the disaster was 173, and over 2000 homes were lost.[135]. The lowest minimum temperature is −10.6 °C (12.9 °F) at Stanthorpe on 23 June 1961 and at The Hermitage on 12 July 1965.

The temperature of 53.1 °C (127.6 °F) at Cloncurry on 16 January 1889 is not considered official; the figure quoted from Birdsville is the next highest, so that record is considered as being official. The calculation of days only includes the days when rain totalled at least one millimetre (0.04 inches). The weather in the northeast region of the state, or the North Coast, bordering Queensland, is hot and humid in the summer, with a rainfall peak, and mild in winter with more sunshine, and little seasonal temperature difference. Australia's seasons are at opposite times to those in the northern hemisphere. Melbourne and other large cities are located in this temperate region.

In contrast, some coastal locations, such as Darwin, have never fallen below 10 °C, and Thursday Island, in the Torres Strait, has an extreme minimum of 16.1 °C. The lowest minimum temperature recorded was −7.2 °C (19.0 °F) at Eyre Bird Observatory on 17 August 2008.[11]. Sandstorm usually refers to dust storms in desert areas when, in addition to fine particles obscuring visibility, a considerable amount of larger sand particles moves closer to the surface. “Annual rainfall was also the lowest on record, surpassing 1902,” he added. [142] Cyclone Mahina in 1899 brought a storm surge to Far North Queensland reaching 13 metres (43 ft) high, causing 400 deaths and making it the worst natural disaster to befall Australia. Annual rainfall for 2013 (187mm) was the lowest since 2002. RAINFALL AND OTHER PRECIPITATION Annual Map 1.4 shows average annual rainfall over the Australian continent. However, they are greatest in the southern inland, with seasonal differences along the coast being moderated by the ocean's proximity. Cyclone Tracy crossed directly over Darwin in 1974, killing 71 persons. The centre of the continent is dry, with annual rainfall less than 100mm. [39], South Australia's mean temperature range is 29 °C (84 °F) in January and 15 °C (59 °F) in July.

Western Australia's climate has changed over the last century, particularly over the last 50 years. ... Average Rainfall: Adelaide. High winds fan the flames, increasing their intensity and the speed and distance at which they can travel. Snow generally falls only in the mountains and hills in the centre of the state. Australia's arid/semi-arid zone extends to this region. In 1902, the national average rainfall total was 314mm, compared to last year’s 277.6mm. A list of extremes can be found in the tables below: Oodnadatta, South Australia (2 January 1960)[103], Thredbo Ski Resort, New South Wales (24 January 2000)[104], Mardie, Western Australia (19 February 1998)[105], Perisher Ski Resort, New South Wales (17 February 1979)[106], Roebourne Airport, Western Australia (10 March 2019)[107], Kiandra, New South Wales (25 March 1964)/Bullocks Flat, New South Wales (31 March 1988)[108], Port Hedland, Western Australia (1 April 1948)/Marble Bar, Western Australia (2 April 1928)[109], Charlotte Pass, New South Wales (29 April 2009)[106], Bidyadanga, Western Australia (6 May 1990)[110], Charlotte Pass, New South Wales (24 May 2008)[111], Wyndham, Western Australia (2 June 1962)[112], Charlotte Pass, New South Wales (29 June 1994)[113], Wyndham, Western Australia (19 July 1996)[114], Charlotte Pass, New South Wales (20 July 2010)[115], West Roebuck, Western Australia (23 August 2020)[116], Charlotte Pass, New South Wales (14 August 1968)[117], West Roebuck, Western Australia (27 September 2003)[116], Charlotte Pass, New South Wales (20 September 1967)[118], Port Hedland, Western Australia (22 October 2002)[119], Charlotte Pass, New South Wales (29 October 2006)[120], Birdsville, Queensland (17 November 1990)[121], Charlotte Pass, New South Wales (26 November 1968)[122], Nullarbor, South Australia (19 December 2019)[123], Thredbo Ski Resort, New South Wales (13 December 1976)[124], Climate change is predicted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO)[126] to have significant effects on the climate of and extreme weather events in Australia, increasing temperatures and the likelihood of heat waves. Hence, rain clouds are sparsely formed and rarely do they form long enough for a continuous period of rain to be recorded. Because Australia is a medium-sized continent, separated from polar regions by the Southern Ocean, it is not subject to movements of frigid polar air during winter, of the type that sweep over the continents in the northern hemisphere during their winter. The highest maximum temperature recorded was 49.8 °C (121.6 °F) at Menindee in the state's west on 10 January 1939.
