New South Wales, Victoria, and Tasmania reported their warmest winters on record, with Melbourne matching its 2005 average winter temperature of 12.2°C. The Bureau of Meteorology forecasts continued above-average temperatures across much of the country, influenced by a developing El Niño and persistent high-pressure systems.
Australia's winter mean temperature was 1.45°C above the historical average, marking the third-highest since records began in 1910. While some regions experienced increased rainfall, others faced below-average precipitation, raising concerns about the impact on ecosystems and industries such as tourism.
