Severe storms also formed on the 13th over southeast Queensland and the Wide Bay region. Dangerous fire weather conditions in early November had led to renewed fire activity in New South Wales and eastern Queensland, with the fires continuing to burn throughout December. The effect of the frost was compounded by antecedent low rainfall, and high temperatures following frost early in the month, as well as crops being at a vulnerable stage of development. Flooding was extensive and long-lived in the Gulf Country, with major flooding at Walkers Bend on the Flinders River by 2 February. The 1974 event resulted in the Lake being completely covered, while in 2011 it was at least 85% covered. Extremes Temperature area averages are derived from the ACORN-SAT version 2 dataset. The Busbys Flat fire had started during 4 October, and by the 9th the combined area burnt by both fires was more than 78 000 hectares. A major influence on this drying has been the strengthening and extension of the subtropical high pressure ridge during winter, shifting many potential rain-bearing weather systems south of the Australian continent. In winter, temperature ranges from 6 to 13 °C, and only 8 hours of sunshine. May days remained warmer than average for the northwest and coastal southeast, and while nights were warmer than average across the north. The index peaked at +2.15 °C for the week ending 13 October, well above the previous record of +1.48 °C for the week ending 5 November 2006. Temperature in Australia increased to 28.06 celsius in December from 26.95 celsius in November of 2015. Large fires affected Gippsland in Victoria and parts of Tasmania from summer into autumn, burning large swathes of remote and wilderness regions. Major flood levels were recorded across the Channel Country catchments (Georgina/Eyre, Diamantina, and Thomson/Barcoo/Cooper). The very strong positive Indian Ocean Dipole (IOD) led to a delayed onset and a delayed withdrawal of the Indian Monsoon, resulting in large precipitation deficits over the Indian subcontinent during June, but above average rainfall in later months. Values remained above the previous record from mid-September to mid-November. Mean maximum temperatures were above to very much above average for most of Australia from September through December. Adelaide. Sydney, Australia: Annual Weather Averages. The transition of the monsoon trough into the southern hemisphere was very late, and the positive IOD persisted beyond the end of 2019. A number of stations set records for their warmest summer day in late December to early January in Victoria, Tasmania, New South Wales, and South Australia, as did a few stations in Western Australia. Above average annual SSTs have been observed for the Australian region for every year since 1995, and have been persistently high for the past decade. January is the hottest month in Adelaide with an average temperature of 23°C (73°F) and the coldest is July at 11°C (52°F) with the most daily sunshine hours at 10 in February. The very strong positive IOD during 2019 has contributed to another late start to the northern wet season in 2019–20, with no monsoonal activity seen across northern Australia before the end of 2019. Warming associated with anthropogenic climate change has seen Australian annual mean temperatures increase by over one degree since 1910. Temperature in Australia averaged 21.64 celsius from 1852 until 2015, reaching an all time high of 29.86 celsius in January of 2013 and a record low of 12.53 celsius in July of 1891. The wintry blast was not rare for spring, which Imielska said brought “changeable conditions”. Temperature values from the observational datasets commence in 1880 for NOAAGlobalTemp and GISTEMP and in 1850 for HadCRUT4, while the two reanalysis datasets commence in 1958 for JRA and 1979 for ERA. More details can be found in the report on severe tropical cyclone Trevor. The full summer begins at around November so tourists are recommended to attend southern cities. Humidity: 63%. It is unusual but not unprecedented to have successive positive IOD events. The dust contributed to ambulance staff attending to a higher than usual number of patients with breathing difficulties. You can access these datasets on our website. 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 … The other main driver of natural climate variability in Australia, the El Niño–Southern Oscillation (ENSO), remained neutral throughout 2019. On two consecutive days, the 17th and 18th, records were set for Australia's hottest day on record. The Bureau of Meteorology has released its annual summer climate outlook, forecasting above-average daytime temperatures across parts of south-east and far-west Australia… In Sydney, the summers are warm and partly cloudy and the winters are short, cool, and mostly clear. The SES received 183 calls for roof and structural damage, water ingress, and downed trees. Based on weather reports collected during 1985–2015. Eleven tropical cyclones were recorded in the broader Australian region during the 2018–19 tropical cyclone season, equalling the long-term average (for all years since 1969–70). While recent heavy rainfall has eased dry conditions in the far east, further inland drought persists. Early reports estimated the damage bill as in excess of one hundred and twenty million dollars. Some stations also observed record warm nights for summer in New South Wales in late December or late January, in Victoria and New South Wales in the first days of February, and in Queensland scattered across the season. In north Queensland, trees were defoliated and felled, buildings were damaged at Lockhart River, and roads were cut due to localised flooding. The frequency of extreme heat events has increased approximately fivefold since the 1950s. All Year January February March April May June July August September October November December. The fires threatened communities in several parts of Tasmania, with the Tasmanian Fire Service issuing Emergency Warnings on many occasions. A hail storm in the Riverland District of South Australia on the evening of 4 November caused crop damage along a narrow band between Murray Bridge and Renmark. The 'filling' season has been below average for the past three years in the Murray–Darling Basin, and runoff in 2019 was the second-lowest on record behind 2006. February 19, 1998: WA's highest recorded temperature of 50.5 is set at Mardie. Frosts caused crop damage to some grain-growing regions in southern Australia. Much of northeastern New South Wales and southeastern Queensland, pastoral South Australia, the central and southern Northern Territory, and southeastern Western Australia received their lowest annual totals on record. The SES responded to 74 requests for assistance, most related to downed trees and other wind related damage. The strong northerlies which had driven these high temperatures over the New Year period also saw a significant increase in fire activity over eastern Australia. Further afield, SSTs were warmest on record for large areas around New Zealand. The total area burnt by the end of January was estimated at over 178 000 hectares, or about 2.6% of Tasmania. Hobart and Sydney had their second-warmest annual mean temperature. The Arctic was also unusually warm during 2019, with above average fire activity. They were warmest on record for much of southern Western Australia during September, northern Western Australia during October, and for very large parts of the mainland during December. In South Australia storms on the 8th brought strong and damaging winds and localised flooding to the Adelaide Hills, with power blackouts affecting thousands of properties across the State. In the low-lying regions of western Queensland, floodwaters spilled from the Flinders River into neighbouring catchments. At night temperatures vary from 20°C in summer to freezing zero in winter. January, March, and December were the warmest on record, with January and December exceeding their previous records by a substantial 0.98 °C and 1.08 °C respectively. Temperatures in the mid to high 40s were observed across large areas, in cases for several consecutive days, including at Perth where temperatures reached 40 to 41 degrees each day from the 13th to 15th. Autumn (March – May) 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%.
