The 2023 Australian Winter was the warmest on record, showing an average of 1.53°C above the 1961-1990 average.[1] The winter began on June 22 at the winter solstice, and concluded with the September equinox on September 23.[2] The meteorological winter began on June 1, and finished on September 23.[3]
Seasonal forecasts
On May 25, 2023, the Australian Bureau of Meteorology released their forecasts for the upcoming winter. The maximum and minimum temperatures were predicted to be very likely (>80% chance) to exceed the average recorded between 1981 and 2018.[4]
The precipitation levels during this time were predicted to have between a 20 and 40% chance of exceeding the accepted median for most of the country, however far northern Queensland showed signs of having above average rainfall.[4]
Due to the El Niño and positive IOD (Indian Ocean Dipole), snowfall was forecasted to be below average for the season in the Australian Alps. Based on previous snow measurements at Spencer's Creek, NSW dating back to 1954, the average snow season in Australia tended to peak at around 198cm, however the forecast predicted a drop in about 36cm.[4]
Seasonal summary
Queensland experienced its warmest June on record, and in July, most of Tasmania and south-eastern Australia also saw their warmest July ever. In August, the national mean maximum temperature was the second highest on record, with daytime temperatures ranking in the top 10% of historical observations across most of the country.[5] Precipitation levels in the country tended to be below average in costal city suburban areas, however well above average in north-central Australia. Overall, the year showed slightly above average precipitation at just over 1.6% above the mean.[6]
Snowfall in the Australian Alps started off slow, and peaked at 131cms as of July 13th. This was the lowest reading since the 2006 season which had a peak of 85.1cms.[7] These low levels of snow could be attributed to the below average levels of precipitation and abnormally high temperatures seen throughout the season. Because of this, all of the Australian ski resorts had to postpone their opening day. A series of cold fronts delivered in the later stages of June, most notably between 19th-20th getting 30-35cm, and June 22-27 delivering between 55-80cm of snow. On July 8th snowstorm passed through, dumping fresh powder. Poor conditions following this led to a period of low snowmaking and overall a below-average season with many runs on some mountains being shut for the remainder of the season. The season ended prematurely compared to previous years due to the conditions.[8]
