Australia records warmest winter caused by global heating and sunny conditions
NSW, Queensland and Tasmania experienced hottest winters with spring likely to deliver hotter than average temperatures too
Good work team.
Australia's winter of 2023 was the warmest since official records began in 1910, with average daily temperatures 1.53C above the long-term average.
Global heating and weather conditions that delivered sunny days were behind the record, scientists said.
For maximum temperatures, the 2023 winter was 1.85C above average, ranking second behind the mark of 1.94C set in 2017.
El Nińos are linked to higher than average sea surface temperatures in the equatorial Pacific but while those conditions are present, the bureau has said it has not yet seen a consistent weakening of the east-to-west trade winds that are also typical of the climate pattern.
"We are already seeing longer fire seasons, and an increase in the number of dangerous fire weather days over most of Australia. We don't know yet how global warming, and particularly the increased warmth in the oceans, is affecting our typical climate drivers."Our climate forecast model is consistent with the international climate forecasts that show Australia is trending dry and warm for the coming season, particularly in the south-west and much of south-eastern Australia.
