Records Shattered: Australia Faces Final Day of Brutal 50°C Heatwave
By Lions Roar Aotearoa Climate & Weather Desk
ADELAIDE/SYDNEY (Saturday, January 31, 2026) — Southeast Australia is enduring the final, sweltering day of an unprecedented eight-day heatwave that has seen temperatures climb to an official 50.0°C—the furthest south that such a temperature has ever been recorded on the continent.
While a long-awaited “southerly buster” has begun to cool the southern coastline, the interior remains trapped under a “heat dome” that has rewritten the Australian record books this week.
🌡️ Historic 50°C Benchmark Reached
For only the eighth and ninth times in official history, Australia recorded temperatures of 50.0°C or higher this week.
- The Record Breaker: Port Augusta (SA) hit 50.0°C on Friday, making history as the southernmost point to reach the half-century mark.
- Andamooka (SA): Also reached 50.0°C on Thursday, marking the first time in four years any Australian station has hit the 50°C milestone.
- The Comparison: Prior to this week, 50°C had only been recorded in South Australia during the infamous 1960 heatwave.
🔥 A Final Day of Sweltering Inland Heat
The “heat dome”—a mass of hot air trapped by high pressure—is delivering its final blow to inland New South Wales and Queensland today.
- NSW Forecasts: Ivanhoe is bracing for a potential record-shattering 49°C, while Wilcannia and Menindee are expected to hit 48°C and 47°C respectively.
- Queensland: The mercury is set to soar to 46°C in Thargomindah and Birdsville.
- Western Sydney: While the coast stays near 30°C, Western Sydney is expected to reach 38°C, with the Hunter Valley hitting 43°C.
🌬️ The Great Cooling: Drops of up to 18°C
Relief is moving north. A cold front from the Southern Ocean is set to displace the heat dome over the next 48 hours.
- Immediate Relief: Southern Victoria and coastal SA have already felt the change. In Seymour (VIC), the temperature is expected to plummet from 39°C to 21°C—an 18-degree drop in just 24 hours.
- Overnight Changes: Regions like Renmark (SA) should see temperatures fall from the low 40s to a manageable 21°C by midnight tonight.
- The Final Holdouts: Northern inland NSW and southwest Queensland will suffer through one more night above 30°C before the southerly change arrives late Sunday.
