In the tropics, extreme minimum near or below 0 °C have occurred at many places distant from the coast, as far north as Herberton, Queensland (−5.0 °C). These annual precipitation statistics are long-term historical averages of weather data collected during 1981 to 2010. A similar calculation of the leading annual rainfall EOT in AWAP, with a mask applied, found this EOT to be located farther northeast and associated with only 25% of space–time variance across Australia (not shown). Eighty-five per cent of the state's runoff occurs in the Kimberley, but because it occurs in violent floods and because of the insurmountable poverty of the generally shallow soils, development has only taken place along the Ord River. 1–5mm80% Gordon. For the most part it is mainly a very dry country, with interior areas often affected by drought for several years – in fact, 80% of the land receives less than 600 millimetres of rain each … Australia; WA; 5–10mm75% Perth. In 1902, the national average rainfall total was 314mm, compared to last year’s 277.6mm. There are five predominant climatic zones in Queensland,[27] based on temperature and humidity: However, most of the Queensland populace experience two weather seasons: a winter period of rather warm temperatures with minimal rainfall, and a sultry summer period of hot, sticky temperatures and more rain. Australia Average Annual Precipitation Climate Map, with Color Coded Yearly Rainfall Amounts. The seasons are more defined in the southern half of the state, especially in the South West Slopes, Central West and the Riverina regions. [138] State Governments are responsible for declaring a region drought affected and the declaration will take into account factors other than rainfall. Cold ocean currents off the coast of Western Australia result in little evaporation occurring. Australian rainfall deciles since 1900. Air from the Southern Ocean helps reduce the heat of summer and the cold of winter. The highest 24‑hour rainfall on record in Australia was 907.0 millimetres (35.7 in) in Crohamhurst on 3 February 1893. The largest part of Australia is desert or semi-arid. 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]. June is … Temperature:. Comparatively, most inland (non-mountainous) areas south of the tropics have average July minimum between 0 and 6 °C. Occasionally, tropical cyclones can bring heavy rainfall to tropical coastal regions, which is also likely to reach further inland. 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. The sea in Adelaide is … [89] A place inland near Lake Eyre (in South Australia) would only receive 81 mm (3 in) of rain annually. Data for 2017 is not available. 51–57.

Find the best time to go to Sydney (New South Wales). Hunt. 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. [96] Extreme snow events have also produced snow as far north-west as Longreach in Queensland and in the ranges near Alice Springs, and also in lowland towns such as Dubbo and Wagga Wagga in New South Wales. Annual Weather Averages in Adelaide. Some areas situated in or around the range, such as Bathurst, Goulburn and Bowral, among other places, have recorded freezing and/or near-freezing lows in most months of the year, unlike other places of similar latitude and altitude in the northern hemisphere. New Zealand ranked second for average rainfall in depth > mm per year amongst High income OECD countries in 2008. Plan ahead with this information on weather and rainfall in Australia’s capital cities. Many locations in this region have recorded −10 °C or lower, including Gudgenby in the Australian Capital Territory (−14.6 °C) and Woolbrook, New South Wales (−14.5 °C). The record number of consecutive days in Melbourne over 40 °C is five, with Brisbane and Sydney each having two.

Smith (2004) found the leading EOT of annual rainfall, located in southwest Queensland, was associated with 60% of variance. Light nighttime frosts in winter occur over much of the southern half of the arid zone, where mean July minimum temperatures are mostly in the 3 to 6 °C range. 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. Here is the average rainfall. The average annual rainfall in Victoria ranges between 1800 – 2500mm in the elevated northeastern areas and 200 – 300mm further west and in the Mallee.

Rainfall … Overnight minimum temperatures have warmed more rapidly than daytime maximum temperatures. Due to the offshore Leeuwin Current, the area numbers in the top six regions for marine biodiversity, containing the most southerly coral reefs in the world. Such occasions are rare, but have occurred in 1958, 1965, 1986, 2005 and 2015, the 1965 event causing snow to fall as far north as Eungella, near Mackay in tropical Queensland. Suburbs of Sydney like Drummoyne and Concord on rivers like the Parramatta River face risks of inundation of low-lying areas such as parks (such as Timbrell Park and Majors Bay Reserve) reclaimed from mudflats at the heads of bays, or massive expenses in rebuilding seawalls to higher levels. Sydney, Australia: Annual Weather Averages. Western Australia Rainfall. South-eastern Australia Rainfall across south-eastern Australia is highly variable on inter-annual and decadal time-scales (Figure 4).

Many of the higher mountains in the territory's south-west are snow-covered for part of the winter. The average and annual rainfall in 80% of Australia … Australia's climate is governed mostly by its size and by the hot, sinking air of the subtropical high pressure belt (subtropical ridge). Same as hot and humid climatic conditions, the rainfall in Australia also exhibits varied temperatures greatly depending on the location while the interior regions of Australia experiences very less amount of rainfall. The centre of the continent is dry, with annual rainfall less than 100mm. [89] The regions between Broome and Exmouth are most prone to cyclones. The late-20th century warming has been largely attributed to the increased greenhouse effect. Tasmania's lowest recorded minimum temperature was −14.2 °C (6.4 °F) on 7 August 2020, at Liawenee.[48]. Average temperatures are less than 9 °C (48 °F) in winter and below 0 °C (32 °F) in the highest parts of the ranges. Australia's Lake Eyre region has the lowest annual rainfall.

However, as experts have cautioned, looking at a region's annual rainfall average isn't necessarily representative of the broader rainfall trend. In most of the desert region during summer, cool days are rare and usually associated with major rain events—a rather exceptional example occurred in February 1949, when many areas failed to reach 20 °C on one or more days, and the maximum at Boulia, western Queensland was at 14.4 °C, which was 23 °C below normal. The lowest minimum temperature recorded was −7.2 °C (19.0 °F) at Eyre Bird Observatory on 17 August 2008.[11].
