Australia is anticipating its warmest spring on record, following a winter that shattered temperature records and led to one of the least successful snow seasons in recent history. The intensifying 'Super El Niño' in the Pacific Ocean is expected to bring hotter temperatures and lower rainfall through the summer months, increasing the risk of bushfires and drought.
Meteorologists from Weatherzone have described the recent snow season in the Australian Alps as one of the worst on record. Ski fields such as Selwyn in New South Wales and Mt Baw Baw in Victoria were compelled to close early due to insufficient snowfall. This lack of snow has had significant financial repercussions, with the Thredbo Alpine Resort experiencing a substantial drop in value.
Record Warm Temperatures and Late Snowfall
The country recorded its warmest winter ever, with New South Wales, Victoria, and Tasmania all experiencing record-breaking seasonal temperatures. Sydney, Melbourne, and Canberra registered their warmest winters since records began in 1859, 1855, and the 1920s, respectively. Average winter temperatures in these cities were 15.29C, 12.18C, and 8.14C.
Ben Domensino, a meteorologist with Weatherzone, explained that the snowpack did not establish until July, and subsequent periods of warm air and rain hindered natural snow depth. "Large areas of the Alps, particularly the lower elevations, have struggled to maintain much of a snowpack at all this season," Domensino stated. He also noted that the season started late, with snow typically beginning to accumulate in May or June and peaking in late August or early September.
'Super El Niño' and Future Climate Concerns
The Australian Bureau of Meteorology declared a 'Super El Niño' in June, following four months of consistent warming in the tropical Pacific Ocean. This event is projected to be one of the strongest on record since 1950. While El Niño events are typically associated with drier conditions and higher temperatures in central and eastern Australia, the bureau cautioned that the impacts may be more severe than in the past due to long-term climate warming trends. The combination of El Niño and a drying trend in southern Australia in recent decades raises concerns about increased extreme heat and drought.
A spokesperson for the Bureau of Meteorology acknowledged that El Niño years often result in lower peak snow depths but emphasized that snowfall is highly variable. The spokesperson also noted the complexity of climate systems, stating that El Niño is not the sole factor influencing Australia's weather. "As the climate warms, the impacts of El Niño on Australia's rainfall may differ from our experience with past events," the spokesperson said. Warmer conditions are known to intensify the risks of drought and bushfires associated with El Niño events.
