Australia is bracing for a dramatic change in weather as a cold polar air mass sweeps across the southeastern region, ushering in temperatures that could drop by as much as 20 degrees Celsius within a single day. This significant shift marks the end of unusually warm spring days for many cities, including Sydney, Melbourne, and Brisbane.
Temperature Forecast and Its Impacts
The forecast shows a stark drop in temperatures due to a wave of icy winds. For instance, Sydney is predicted to see temperatures plummet from a warm 31 degrees Celsius to around 12 degrees by Thursday afternoon. Such a sudden swing is rare and alarming for residents, particularly following warm weather that has lingered over the past week.
Key temperature predictions include:
- Sydney: From 31°C to about 12°C in 24 hours.
- Melbourne: From 25°C down to 14°C by Thursday.
- Brisbane: A slight drop from 29°C to 22°C.
- Tasmania: Coldfront snow levels could drop to sea level.
The Bureau of Meteorology (BoM) has confirmed that this weather pattern is due to a southerly airstream originating near Antarctica, which will replace the warm north-westerly winds that have dominated the atmosphere. This has not only brought cool temperatures but also promises widespread rain and even snow in elevated areas, particularly in southeastern states.
Widespread Rainfall Across Australia
With the temperature drop comes a forecast for significant rainfall across much of eastern Australia. This weather event is anticipated to be unusual for September, typically the country’s driest month. The projected rain is attributed to a north-west cloudband that has already delivered record rainfall to parts of western Australia.
Key rainfall predictions include:
- NSW: The eastern part of the state could accumulate 10mm to 40mm, with certain areas like the Illawarra and the southern tablelands potentially receiving even more.
- Brisbane: Expecting rain later in the week, though not as severe as in NSW.
- Southern Tasmania: Snowfall is expected with up to 300mm possible in the Alpine regions.
Already this week, Uluru has recorded its wettest September day in history, with over 32mm of rainfall. As rainfall reaches greater coverage, officials warn of flash flooding and minor river rises, urging residents to stay safe.
Emergency Preparedness and Safety Measures
As the severe weather approaches, the New South Wales State Emergency Service (NSW SES) is on high alert. Chief Superintendent Sonya Oyston emphasized the importance of preparedness in light of possible flash floods. “Our incident management teams are ready to respond quickly to any emergencies,” she stated.
Residents are advised to:
- Monitor local weather reports.
- Have an emergency kit ready.
- If encountering floodwaters, turn around and find an alternate route.
With severe weather patterns capable of causing significant disruption, it is crucial for everyone to keep safety as a top priority.

Weather Extremes This Spring
The swift transition from warm to chilly conditions reflects spring’s often fickle nature in Australia. This week, temperatures across southeastern states could showcase a remarkable contrast. For example, regions like Cooma, Jindabyne, and Nimmitabel may see snow due to the cold air masses pushing in from the south.
Interestingly, while southeastern Australia could experience some of the coldest temperatures, the northern areas may remain warmer, showcasing a significant temperature divide. This sharp contrast has residents curious and anxious about the unpredictable nature of the Australian climate.
Final Thoughts
As the weather system develops, attention remains focused on the significant changes in Australia’s climate expected this week. From record rainfall to substantial temperature drops, residents are navigating an unpredictable weather pattern.
This week’s weather is changing, and it’s important to stay updated and ready. A cold front is coming, bringing heavy rain and the chance of flooding. This reminds everyone in Australia that the weather can change a lot from season to season. It’s a good time to think about safety as the chilly spring weather takes over from the warm summer days we had.
