The Bureau of Meteorology’s (BoM) spring outlook shows above average daytime and night-time temperatures are expected to continue for much of the country, with an increased chance of unusually high maximums.  Dr Simon Grainger, a senior climatologist at the bureau, said (https://www.theguardian.com/australia-news/sydney) Sydney had its warmest winter on record, with the mean temperature of 15.3C at Observatory Hill breaking the previous record of 15.0C set in 2013. Average maximum and minimum temperatures at the same site were also the warmest on record.

New South Wales, Victoria and Tasmania had their (https://www.bom.gov.au/climate/current/season/aus/summary.shtml) warmest winters on record, and all other states and territories except the Northern Territory were in their top 10 warmest winters on record since 1910.   (https://interactive.guim.co.uk/datawrapper/embed/eD525/2/) How the most recent winter compares with previous years.    Australia’s mean temperature was 1.45C above the 1961–1990 average for winter, the equal third-highest on record since national observations began in 1910. Grainger said much of the south-east’s experience was driven by “relatively warm nights and a lot fewer cold nights”, with several factors at play. “The local weather patterns certainly assisted. For large parts of this winter we had high pressure systems sitting in the Tasman sea,” he said. “That allowed a lot of warmer air to come down from the tropics over eastern Australia – places like Sydney, Canberra, Melbourne – with fewer outbreaks of cold air getting in.” Grainger said the developing strong El Niño had also set up weather patterns that tended to be favourable for high daytime temperatures across southeastern Australia. “Finally of course, all of this is occurring against the background of a globally warmer climate,” he said. “Daily [global] land temperatures and daily ocean temperatures during August have been close to or above the historical records that were set only in 2024.”   (https://interactive.guim.co.uk/datawrapper/embed/tstND/1/) Graphic showing the difference between the mean temperature of the period specified and the long-term average.

Grainger said parts of inland NSW, (https://www.theguardian.com/australia-news/victoria) Victoria , South Australia and parts of the Northern Territory had above average rainfall, with parts of far-western NSW near the SA border experiencing their wettest winter on record. SA recorded its sixth wettest winter on record. In contrast, rainfall was below average in parts of the east coast and south-western Australia. The BoM’s long-range forecast shows below average rainfall is expected to continue through parts of southern and eastern Australia through spring, while above average rainfall is expected in large parts of the west from October. Grainger said a continuation of above average daytime and night-time temperatures was likely for much of the country “and with that there’s [a] chance of unusually high maximum and minimum temperatures”. He said the BoM’s models showed the El Niño in the Pacific Ocean would continue to strengthen through spring, likely peaking in late spring or in summer. Prof Sarah Perkins-Kirkpatrick, a climate scientist from the Australian National University, said while some people might enjoy the idea of a warmer winter, it had negative consequences for the environment. “We need to consider what’s happening to our natural ecosystems,” she said. “A lot of our ecosystems need cooler temperatures, a lot of our animals are used to it, and if we start taking that out of the picture, then things aren’t looking so healthy.” She pointed to the recent snow season, where low falls had also affected the tourism industry, with resorts in Victoria and NSW forced to close early. “Snowfall in Australia is pretty rare, and just notching the temperature up to a couple of degrees during winter basically puts us above freezing point most of the time,” she said.
