Very much cooler than average monthly mean SSTs were seen to the south of the Indonesian island of Sumatra in October and November, when the event was at its strongest, with some areas coolest on record for their respective months. Several datasets have been developed from this archive to identify, monitor and attribute changes in the Australian climate. (Averages of maximum temperatures during the day, and averages of the minimum temperatures at night.) The national area-averaged maximum temperature on the 18th was 41.9 °C, a whole degree above the value for the 17th (40.9 °C). Flooding continued in western Queensland into April, boosted by above average monthly rainfall for large areas in March, partly as a result of severe tropical cyclone Trevor, which crossed the Peninsula during the second half of the month. Of the ten warmest years, only one (1998) occurred before 2005. All Year January February March April May June July August September October November December. Extremes Plan ahead with our information on temperature and rainfall. More details on dangerous bushfire weather and heat in spring 2019 can be found in the related Special Climate Statement. The fires threatened communities in several parts of Tasmania, with the Tasmanian Fire Service issuing Emergency Warnings on many occasions. The end of year period brought particularly challenging weather, with the FFDI for individual days the highest on record for December, and in some cases for any month, on 30 and 31 December over areas of southeastern Australia and Tasmania. The first days of December saw a cool spell with record low summer daily maximum temperature at a handfull of stations in Victoria, Tasmania, and elevated locations in New South Wales. The notable warmth of 2017, 2018, and 2019 occurred without the presence of El Niño (which typically boosts global temperatures). The period around New Year's saw particularly hazardous fire weather, with further significant fires igniting while existing fires experienced renewed flares. Sea surface temperatures were very much warmer than average across waters to the east of Australia from southeast Queensland to the Tasman Sea and eastern Bass Strait during 2019. Flooding was extensive and long-lived in the Gulf Country, with major flooding at Walkers Bend on the Flinders River by 2 February. Rainfall was below average in all the capital cities. Large fires affected Gippsland in Victoria and parts of Tasmania from summer into autumn, burning large swathes of remote and wilderness regions. Both of these values exceed the previous record of 40.30 °C set on 7 January 2013. Conversely to the drying trend in the south, there has been an observed increase in rainfall over parts of northern Australia since the 1970s. This trend towards wetter years in the north is contributing to a slight increase in mean annual rainfall for Australia as a whole. Monday 2 March 2020 Daytime temperatures were especially warm, with Sydney, Canberra, Brisbane, and Hobart all observing their highest annual mean maximum temperature on record. Darwin had its seventh-driest wet season over 2018–19, and a late start to the 2019–20 wet season. Sea surface temperature values are provided for a boxed region around Australia (4–46 °S and 94–174 °E). SSTs were near average around the Northern Territory and Queensland's Cape York Peninsula. Major flooding resulted along the Pilbara coast with both Port Hedland and Karratha cut off by flooding and multiple roads closed in the region, including the Great Northern Highway and North West Coastal Highway. May was much drier than average for most of Western Australia and much of east coast Australia. In the low-lying regions of western Queensland, floodwaters spilled from the Flinders River into neighbouring catchments. High Temp: 88 °F. Low rainfall also led to very low soil moisture across large areas of Australia during 2019, particularly across the Murray–Darling Basin. Significant heat affected large parts of central and southern Australia from 12 December as a slow-moving high over the Great Australian Bight allowed heat to build over the continent. All the years since 2013 have been amongst the ten warmest on record for Australia. The transition of the monsoon trough into the southern hemisphere was very late, and the positive IOD persisted beyond the end of 2019. Recurrent periods of high temperatures and windy weather saw little reprieve. Significant flooding was also recorded in the Bulloo, Paroo, and Warrego catchments during early to mid-April but the most significant flooding was recorded further to the west. Some checks have been made on the data, but it is possible that results will change as new information becomes available, especially for rainfall where much more data becomes available as returns are received from volunteers. Widespread areas of heavy smoke created hazardous air quality across broad areas of eastern Australia at times during spring through December, in some locations lasting for weeks at a time with little respite. The “long-term increasing trend in global air and ocean temperatures” was a factor in the hotter-than-average summer, the report said in October. For the Tasman Sea region monthly SSTs were amongst the three warmest on record for each month from January to July, and the fifth-warmest on record for August. There were also reports of significant impacts on wildlife due to heat stress. While the effect of the protracted period of below average rainfall was severe across the Murray–Darling Basin, serious rainfall deficiencies on annual to multi-year timescales also affected coastal New South Wales; eastern Victoria; eastern South Australia, extending into far northwestern Victoria; east coast and north coast Tasmania; and much of the South West Land Division in Western Australia. Precipitation: 1.20". Very heavy rainfall led to flash flooding in the metropolitan region, with the Brisbane city gauge reporting 103 mm in one hour, delivering December's average rainfall total in one night. Both days exceed the previous record of 40.30 °C set on 7 January 2013. 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). By the end of 2019 water storage in the Northern Murray–Darling Basin had dropped to less than 7% of capacity. The fire at Long Gully Road continued to burn in bushland south of Drake, Tabulam, and the Bruxner Highway, having reached 47 500 hectares. Negative SAM is also associated warmer than average spring temperatures and an increased chance of spring heatwaves across southern and eastern Australia. Some areas had settled snow, with 5 cm to 8 cm at Goulburn. Widespread thunderstorm activity was observed across New South Wales associated with the passage of a strong cold front on 26 November. A cold front and a low pressure system that crossed Victoria on 9 and 10 May brought heavy rainfall and flash flooding to Ballarat and Geelong, as well as snowfalls in the Victorian Alps. The national area-averaged maximum temperature on the 18th was 41.9 °C, a whole degree above the value for the 17th (40.9 °C). Summer (December – February) During summer, average temperatures range from 16.7 - 28.6°C (62 - 83.5°F) and rainfall is sparse. On 17 November, severe thunderstorms developed over southeast Queensland. Annual rainfall totals were in the lowest 10% of historical observations for almost 70% of Australia, encompassing most of New South Wales and the southeastern quarter of Queensland; large areas of northwestern, northeastern, and eastern Victoria; eastern Tasmania; most of South Australia; most of the Northern Territory except some eastern regions; and much of Western Australia except some parts of the Kimberley, northwest, Gascoyne, and Goldfields. Nationally-averaged rainfall for 2019 was 40% below the 1961–1990 average of 465.2 mm. Emergency services responded to about 60 requests for assistance, including eight from Southend where the pattern of damage was consistent with a short-lived tornado. it's always summer somewhere in western australia As the second largest state in the world (half the size of Europe), Western Australia’s sunny climate has shaped … Trevor moved across the Cape York Peninsula and re-intensified over the Gulf of Carpentaria before making a second landfall east of Port McArthur in the Northern Territory as a category 4 system on the 23rd. Perth was equal-warmest and Darwin the second-warmest. 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. The drying trend is particularly strong for May–July over southwest Western Australia since 1970, and for April–October over the southeast of the continent since 1999. Sydney, Australia: Annual Weather Averages. Rainfall totals reached more than four times the March monthly average, equivalent to more than an average year's worth of rainfall. Agriculture in the south, which depends on regular rainfall from cold fronts traversing Australia’s south-east in winter, receives less rain in summer.

“It is likely this year will not see the same intensity as the 2010-11 La Niña event, but is still likely to be of moderate strength,” the weather bureau added. The mean temperature for summer was the second-warmest on record for Queensland, Western Australia, and the Northern Territory, the fourth-warmest on record for New South Wales, and the sixth-warmest on record for South Australia. As such, the SSTs lag the atmospheric temperatures on a seasonal timescale by about 3 months. All of the ten warmest years on record have occurred between 2005 and the present, with El Niño contributing in four of these years. On the evening of 22 March, a thunderstorm associated with a low pressure trough delivered heavy rain and hail to eastern parts of Greater Melbourne. Maximum temperatures for the year were also well above average across all of Australia. You can access these datasets on our website. SSTs were near average to the southwest of Australia, including the west and southwest coasts of Western Australia. A cool change which ended the warm spell also resulted in some stations in South Australia observing record cool days for summer on 5 January. Major flood levels were recorded across the Channel Country catchments (Georgina/Eyre, Diamantina, and Thomson/Barcoo/Cooper). A tornado was reported at Lake Nowergup around midday on the 10th. February is the wettest month (Receiving 184mm/7.2 inches on average), and short, tropical storms are common in the late afternoon and early evening.
