Most of this warming has occurred since 1950. Based on weather reports collected during 1985–2015. See Special Climate Statement Extreme heat and fire weather in December 2019 and January 2020. In general, baseline climatological periods try to make use of the period with the best data coverage. Australia's seasons are at opposite times to those in the northern hemisphere. Following further rainfall around mid-February, all fires in New South Wales, Victoria, and Tasmania were declared contained by the end of February. Rainfall for the year was below average for parts of southeastern and east coast Queensland, the west and southwest of Western Australia, and western Tasmania. Since records began in 1881 there have only been 5 other years when rainfall at Bray Park fell below 1000mm: May–July rainfall was the seventh-lowest on record for southern Australia. ©Bureau of Meteorology Northern wet season (October–April) rainfall deciles for the last 20 years (2000–01 to 2019–20). One of the main reasons for Australia being such a dry country is its location on the map. 20 heavy rain days per year; in the dry south-west, there are on average only 1 or 2 days heavy rain days each year. According to Köppen and Geiger, this climate is classified as Cfa. As one moves further north/north-east the rainfall levels increase very slightly, but only into the … The hardest hit areas were to the west of Geelong. This location is classified as Cfb by Köppen and Geiger. You can access these datasets on our website. South Australia suffered its driest year on record during 2019, the Bureau of Meteorology says, with rainfall down 65 per cent as mean temperatures rose … The original source of this data can be found here. Visibility was severely reduced with many locations reporting less than 200 m. A very hot air mass brought a period of very high temperatures across southern Australia during the last days of January. Cool season tornados are typically observed once or twice a year, but it is rare that they move through populated areas—many may go unnoticed in sparsely populated areas. 20 heavy rain days per year; in the dry south-west, there are on average only 1 or 2 days heavy rain days each year. The interior desert sees its greatest rainfall during spring and summer. Average monthly Rainfall, Sunshine, Temperatures. Snow fell in many Canberra suburbs and settled widely above 750 m, with snowfalls continuing in the Brindabella Ranges over the following days. Severe thunderstorms are likely in southeast Queensland on Saturday, with damaging winds, large hail and heavy rainfall possible. It was amongst the five warmest years on record for Queensland, Western Australia, and the Northern Territory. A period of minimum 30 years is required to form a robust climatological average, accounting for decadal variability. Along with 40.1 °C at West Roebuck on the 27th, Australia had observed three 40 °C days in August within a week. We also have comparison graphs and tables showing Perth rainfall for the past 4 years. Mainland PR Average Rainfall (inches) PR/USVI Average Rainfall (inches) and Percent of Normal Decade 1940-1949 1950-1959 1960-1969 1970-1979 1980-1989 1990-1999 2000-2009 2010-2019 2020-2029 You’ll also notice that this is where the majority of the world’s major desert regions are located, including the Sahara Desert in Northern Africa, as well as the Atacama Desert in South America which has one of the lowest rainfalls in the world 5. Several electricity transmission towers were knocked to the ground near Colac, with Mt Gellibrand reporting a maximum wind gust of 120 km/h. The strength of the La Niña increased again by the end of the November, and reached moderate to strong levels in December. It favoured reduced rainfall over southwest Western Australia, southern Victoria, and Tasmania during May and June, enhanced rainfall across much of southern Australia during much of August, and reinforced the wet La Niña signal in early November and much of December. Many of the storages in northern Australia rely on the regular wet season rainfall to replenish water levels following the drawdown on stored water over the dry season. There has been a decline of around 16% in April–October rainfall over the southwest of Australia. Despite suffering through periods of drought, flooding is a fairly common occurrence in parts of Australia and has been for a number of centuries, resulting in average damages of around $350 per person every year 10. Australia is known for a variable climate and highly variable rainfall which results in substantial variation in wheat yields. This section also experiences extreme heat and dangerous UV index levels, along with periods of drought. The annual 2020 sea surface temperature (SST) anomaly for the Australian region was the equal-fourth-highest on record; 0.59 °C above the 1961–1990 average based on data from the NOAA Extended Reconstructed Sea Surface Temperature dataset, ERSST v5. Second-warmest year on record for Western Australia. Here is the average precipitation. The centre of South Australia is extremely dry, receiving as little as 100 – 200 ml per year. More than 1900 calls for help were made to emergency services and more than 15 000 insurance claims were lodged. While not lasting long enough to be considered a negative Indian Ocean Dipole event, surface temperature patterns in the Indian Ocean reflected a "negative Indian Ocean Dipole-like" state during late winter to early spring, which also favoured above average rainfall over eastern and southern Australia. Rather,  varied changes across different regions are expected, as will be explained in more detail. In Tasmania snow closed the Huon Highway south of Hobart, and a few centimetres fell in Launceston; snow settling on the ground in Launceston is very rare. Above average rainfall and increased cloud cover over the southeast during this period suppressed maximum temperatures. Flooding during March occurred on already elevated river levels in tributaries of the Lake Eyre and Murray–Darling basins. Western Australia saw its second warmest year on record with rainfall below average in the west and above average in the north. The 1961–1990 period is used globally as it coincides with consistent national temperature records observations and allows comparison across countries. Perth’s rainfall was 10 per cent below normal. A cold front and complex low pressure system crossed southeast Australia from 11 July, with the low deepening over the Tasman Sea during the 13th and 14th before moving away to the east during the 15th. A significant heatwave affected much of northwest to southeast Queensland around the middle of November. Although going further up North in Queensland, areas in Bamaga and Weipa are subject to much heavier rainfall, with about 75 rainfall days per year. The broader Australian region covers the area south of the Equator and between 90°E and 160°E, and includes Australian, Papua New Guinea, and Indonesian areas of responsibility. Indonesia ranked second for average rainfall in depth > mm per year amongst Emerging … Several cold fronts associated with a complex area of low pressure brought widespread showers, isolated thunderstorms, small hail and gusty winds to southeast Australia between 21 and 26 September. According to projections made by the Bureau of Meteorology in 2015, Australia is expected to see an increase in average temperature of between 0.6° and 1.7° Celsius by the year 2090, under the assumption of a great reduction in the global emission of greenhouse gases 12. More than 100 houses were severely damaged, as thunderstorms produced a tornado with winds estimated to be in excess of 150 km/h. In Sydney the runoff from this event was enough to almost double the amount of accessible water in Sydney's urban supply system storages. Throughout the year, there are 116.9 rainfall days, and 1006.6mm (39.6") of precipitation is accumulated. The Southern Annular Mode was positive during early November and much of December. The Dampier weather radar sustained significant damage, and Karratha Airport recorded its highest wind gust in 17 years of wind observations (194 km/h on 8 February). An intense dust storm swept through a very large area of South Australia, New South Wales, and Victoria during 23 and 24 January. In this process, the moisture in the air is lost and it warms due to a phenomenon known as compressional heating. A slow-moving low pressure system and coastal trough resulted in very heavy rainfall and flooding for parts of northeastern New South Wales and southeastern Queensland during the middle of December. See State of the Climate 2020 for further information. According to Köppen and Geiger, this climate is classified as Cfa. Sydney, Australia: Annual Weather Averages January is the hottest month in Sydney with an average temperature of 23°C (73°F) and the coldest is July at 13°C (55°F) with … Flash flooding and riverine flooding affected parts of southeast and inland Queensland and inland and coastal areas of New South Wales, extending into the second half of the month. In Sydney, the summers are warm and partly cloudy and the winters are short, cool, and mostly clear. La Niña is also associated with more heavy rainfall events, while El Niño years experience fewer. It is common for mean maximum temperatures to be very much warmer than average over most of Australia during periods of low rainfall during the cooler months of the year, while mean minimum temperatures are cooler than average in the inland southeast. Significant heatwaves affected much of southeast and eastern Australia in late November to early December. Water storages in the southern Murray–Darling Basin increased significantly during 2020, but northern Basin water storage levels remained low. The ocean waters around Australia have also warmed significantly over the past century, and have been very warm consistently across the past two decades. One of the most severe hailstorms recorded in the ACT occurred on 20 January. Perth had lower than average rainfall for the year, while annual rainfall was well above average for Melbourne, Canberra, and Sydney. This was however to a much smaller extent. Heat built in northwestern Australia over August, with records set at a large number of stations in Western Australia during the last week of the month. Rainfall has increased across most of northern Australia since the 1970s. In the southeast of Australia there has been a decline of around 12 per cent in April to October rainfall since the late 1990s. Summer (December – February) During summer, average temperatures range from 18.6 - 25.8°C (65.5 - 78.4°F), and average humidity spikes to 65%. Ahead of the front many stations in New South Wales observed their warmest January day on record on the 4th or 5th. Larger maps, About rainfall maps. A coastal low during mid-December produced prolonged heavy rainfall, flooding, and significant coastal erosion in parts of northeast New South Wales and southeast Queensland. Australia's climate is governed mostly by its size and by the hot, sinking air of the subtropical high pressure belt (subtropical ridge). Maximum and minimum temperatures close to average for most months of the year, but the mean temperature for spring was the warmest on record for the State. A strong cold front brought a band of thunderstorms, accompanied by lightning and winds in excess of 100 km/h to southern central Victoria in the early hours of 20 May. It was the second-warmest year on record for Western Australia as a whole, the fifth-warmest for the Northern Territory and Queensland. El Niño is a natural phenomenon which perhaps has one of the most powerful impacts on Australian climate. More than 1360 requests for assistance were made in the Melbourne region, and more than 3000 insurance claims lodged. Rainfall for Australia was close to average for the nation as a whole at 483.4 mm; 4% above the 1961–1990 average of 466.0 mm. Another main reason has been found to be of a man-made nature, however. A scientific model used in the study predicts up to a 40% decrease in Australian rainfall over the next 40 years. For the Great Barrier Reef region, monthly averaged SSTs were the warmest on record for February and second-warmest on record for March. The Southern Annular Mode (SAM) was positive for much of May and June. The heat across northern Australia continued into spring, with September mean maximum temperatures warmest on record for much of the northwest of Australia, and further early-season records set in the northwest during the first half of the month. The annual mean maximum temperature was also above average for Perth, Canberra, and Brisbane, close to average at most sites across greater Adelaide, and close to average or slightly below average at most sites across greater Melbourne. Sydney, Australia: Annual Weather Averages January is the hottest month in Sydney with an average temperature of 23°C (73°F) and the coldest is July at 13°C (55°F) with … The last days of 2019 and first days of 2020 saw particularly hazardous fire weather, with further significant fires igniting while existing fires experienced renewed flares, as heatwave conditions continued into early January. This page includes a chart with historical data for Australia Average Precipitation. Showers and thunderstorms developed across central and eastern Victoria during the afternoon of the 19th and extended across the southwest in the evening. The middle of the year was notably drier, with May–July rainfall in particular below or well below average across much of the southern half of Australia. This statement has been prepared using the homogenised Australian temperature dataset (ACORN-SAT) for area-averaged temperature values and the observational datasets. It experienced one of the worst droughts in its history between 2003 and 2012, however, has since seen an increase in average rainfall. Following some severe storms in southeast Australia around mid-January, more widespread and very damaging storms affected the region on the 19th and 20th. This moves north-west and north-east with the seasons. Two low pressure systems in the Tasman Sea brought heavy rain, isolated flash flooding, and high seas to coastal New South Wales during July. A cold front and associated trough crossed Victoria during 27 August, resulting in squally westerly winds across southern and mountain districts; Wilsons Promontory Lighthouse reported a wind gust of 157 km/h (85 kts). The average annual temperature in Sydney is 17.6 °C | 63.7 °F. On the 29th many stations in New South Wales had their warmest November night on record, and Delta, west of Bourke, reported a minimum temperature of 33.8 °C, the highest November minimum temperature ever recorded in New South Wales, and the fourth-highest for all of Australia. Spring as a whole was also the warmest on record for Australia in terms of national mean temperature. Rainfall anomalies were very large at longer timescales; below average rainfall over most months over much of the country between early 2017 and the end of 2019 had allowed very large deficiencies to accumulate (see Special Climate Statement Drought conditions in eastern Australia and impact on water resources in the Murray–Darling Basin). Storms resulted in significant coastal erosion and hazardous beach conditions for much for much of the New South Wales coast during mid-July. Waters were also warmer than average for most areas around the southern half of Australia, but close to average in a region south of Tasmania and the the southwest of Western Australia. However, rainfall for the northern wet season was lower than average in both 2018–19 and 2019–20. Damaging storm surges coincided with king tides, resulting in hazardous surf conditions and major coastal erosion at numerous beaches in northeast New South Wales and southeast Queensland. Australian rainfall deciles since 1900. Widespread heavy rainfall during the first half of February across much of Queensland and along the east coast of Australia contributed to both riverine and flash flooding in some areas of New South Wales and Queensland. Heavy rain fell over coastal New South Wales and much of Gippsland, resulting in localised flooding in several areas, including Newcastle, the Lower Hunter, and the South Coast District. The centre of South Australia is extremely dry, receiving as little as 100 – 200 ml per year. Without a significant global reduction in the emission of greenhouse gases, Australia is projected to experience an increase in average temperature of between 2.8° and 5.1° Celsius by the year 2090 13. This further declined to 36.8% in March. They were in the highest 10% of historical observations for most of Western Australia, the Northern Territory, and Queensland away from the southwest. Severe drought affected large parts of the country. The tropical cyclone season typically runs from 1 November to 30 April, although tropical cyclones can and do form outside of those bounds (for instance, Mangga was active during May 2020). Over the course of the year, the temperature typically varies from 47°F to 80°F and is rarely below 42°F or above 90°F.. Based on the tourism score, the best time of year to visit Sydney for warm-weather activities is from late November to early April. Queensland state, a popular holiday destination, allows visitors from the country's two most populous states, New South Wales and Victoria, after closing its borders in August. Waters were warmer than average in parts of the Maritime Continent, and in the north and east of the Indian Ocean during July and August, as the Indian Ocean approached, but did not sustain, a negative Indian Ocean Dipole (IOD) like state. For example average yield nationally in 2002-3 was 0.91 t/ha, whereas in 2011-12 it was more than double that at 2.14 t/ha (Table 1). ... Average monthly precipitation over the year (rainfall, snow) 3. Here is the average precipitation. Storms also affected the Sydney region, with more than 4000 insurance claims arising from strong winds, lightning, and hail in the Sutherland Shire and northern beaches. Strong winds were observed, including gusts in excess of 100 km/h at exposed coastal locations like Byron Bay. This section also experiences extreme heat and dangerous UV index levels, along with periods of drought. Precipitation here is about 1309 mm | 51.5 inch per year. April rainfall was above average for much of southeastern Australia, leading to significant inflows into many southern Murray–Darling Basin water storages. Annual mean maximum temperatures were amongst the ten warmest on record for Queensland, Western Australia, and the Northern Territory. Months with the highest UV index in Gold Coast, Australia, are January , February and December , with an average maximum UV index of 12 . Damaging winds were observed through parts of the Illawarra, Central Tablelands, Southern Tablelands and Sydney Metropolitan areas in New South Wales. December rainfall was above or very much above average for much of the country, and highest on record for the northern coast of New South Wales. By the end of 2020, Wivenhoe Dam in southeast Queensland had dropped to its lowest level in 10 years. Average maximum temperatures in the winter months (June-August) are around 16°C/61°F. The most common cause of floods in Australia is extreme rainfall, which can be caused by the La Niña phenomenon which is the natural cooling of the ocean, resulting in heavy and above average rainfall. All tropical cyclones existing between 1 July and 30 June the following year count towards the season total. Mean minimum temperatures were the fourth-warmest on record at 1.05 °C above average. Daytime temperatures were especially warm for Sydney, Hobart and Darwin, with the mean maximum temperature well above average. The island continent of Australia features a wide range of climatic zones, from the tropical regions of the north, through the arid expanses of the interior, to the temperate regions of the south. 2. Negative IOD events in winter and spring favour above average rainfall across much of eastern and southern Australia, and it is likely sea surface temperature patterns in the Indian Ocean contributed to above average rainfall over Australia between August and October. Severe tropical cyclone Damien crossed the coast near Karratha in Western Australia at category 3 strength. La Niña became established during September, and reached moderate strength by the end of the year. Based on weather reports collected during 2005–2015. Additionally, large areas of Western Australia saw very little rain during April to July, and short-term rainfall deficiencies emerged across much of southwest Western Australia starting from April. In climatology a baseline, or long-term average, is required against which to compare changes in climate over time. Across the same region May to July rainfall has seen the largest decrease, by around 20 per cent since 1970. Western Queensland experienced renewed heavy rain and flooding in the Georgina, Diamantina, Bulloo, Paroo, and Warrego rivers and the Cooper Creek catchment. The rainfall pattern is concentric around the extensive arid core of the continent, which in the west and along parts of the Great Australian Bight extends to … The New South Wales State Emergency Service received more than 1000 calls for help and the Queensland Fire and Emergency Services received more than 1500 calls for help. The climate is variable, with frequent droughts lasting several seasons, thought to be caused in part by the El Niño-Southern Oscillation. This was in addition to the existing multi-year rainfall deficiencies in the region for the period commencing in early 2018. Australia is a vast continent with a wide variety of climates.

In Perth it was the most severe storm since the hailstorm on 22 March 2010. Warragamba, the largest storage in the system, went from 42% of capacity on 8 February to 81% on 18 February, an increase of 800 GL, almost enough water to fill the Sydney Harbour twice over. Renewed heavy rainfall at the end February and in early March, partly associated with the remnants of tropical cyclone Esther, led to further widespread flooding in Queensland and heavy rainfall as far south as Victoria. Reference: Johnson, K. (1992), The AUSMAP Atlas of Australia. Below is an interactive rainfall map of Australia that allows you to click through into each city and town to learn the average mm of rainfall per year, as well as the average number of rainfall days per year. Australia is home to some of the driest regions in the world, while also being subject to periods of heavy rainfall and cyclones. June experienced the least rain in 2017, and had an average rainfall of about 60% less than the June average (between 1961 – 1990). Heatwaves affected parts of Australia several times during November. Mean SSTs for the year were the second-warmest on record for the Northern Australian region and equal-second-warmest for the Coral Sea region, (+0.76 °C for the Northern Australian region, behind +0.96 °C in 2016, and +0.73 °C for the Coral Sea, tied with 2017 and behind +0.83 °C in 2016). Of these years, 2010 was exceptional: the total of 1,112mm was 585mm above average (exceeded only in 1956 with 1,130mm). in the highest 10% of historical observations) across waters around the northern half of Australia and across the northern half of the Tasman Sea. Following Australia's hottest year on record in 2019, 2020 was a year that was both warmer and wetter than average, the Bureau of Meteorology says. The Pacific Ocean began cooling over autumn, with early indicators of a developing La Niña emerging from around June. Southern Australia receives winter rains from depressions associated with the west-wind zone. Three tropical cyclones crossed the coast (Blake, Damien, and Esther). Extreme heat affected northern Western Australia and the Top End of the Northern Territory during August and September. The average annual temperature in Sydney is 17.6 °C | 63.7 °F. January, like December, in Brisbane, Australia, is another warm summer month, with average temperature ranging between min 21.2°C (70.2°F) and max 29°C (84.2°F).The warmest months are January and February, with an average high-temperature of 29°C (84.2°F).In January, the average heat index is evaluated at a tropical 31.5°C (88.7°F). Minimum temperatures during the winter months were below average over much of southeastern Australia during winter while mean maximum temperatures were above or well above average over most of Australia. Local flooding resulted in various parts of Greater Sydney, and there was coastal erosion on multiple beaches. For Australia as a whole June rainfall was the third-lowest on record. The rainfall in Sydney is significant, with precipitation even during the driest month. The first four months of the year were warmer than average for large parts of Australia, particularly across the north, while the southeast experienced cooler than average mean maximum temperatures in February to April. The speed and volume of runoff was likely to have increased due to the lack of vegetation. Storages in the northern Basin remained below 25% capacity at the end of December. It’s easy to see that coastal areas are exposed to much heavier rainfalls, while the central desert regions in South Australia and Western Australia are far dryer. Water storage in the northern Basin had reached a record low of 5.4% of combined capacity in mid-January 2020, 7.5% lower than at any point during the Millennium Drought, and did not reach above 26% during the year before dry conditions and downriver releases saw levels decline in late spring. By the end of 2020, Darwin's water storages and Wivenhoe in southeast Queensland had dropped to their lowest levels in 10 years, and Lake Argyle in the eastern Kimberley had dropped to its lowest level in almost 30 years.
