Key Takeaways
- Severe Tropical Cyclone Fina is directly related to the near-record-breaking temperatures in Australia’s interior, with temperatures above 45°C experienced in three states.
- The hottest temperatures were recorded in South Australia, Queensland, and New South Wales, with Marree in South Australia being the hottest at 46.2°C.
- The heat event is expected to dissipate on Tuesday, with some of it tracking towards the east coast, bringing high temperatures to cities like Sydney and Brisbane.
- The heat is a result of Severe Tropical Cyclone Fina drawing vast amounts of heat from the warm surface waters of the Timor Sea and transporting it into higher levels of the atmosphere.
Introduction to the Heat Event
A large portion of Australia’s interior is experiencing near-record-breaking temperatures for November, with the searing heat being directly related to Severe Tropical Cyclone Fina. As of 5pm Monday (AEDT), temperatures above 45°C were experienced in three states, with the hottest readings in each of those states being recorded in South Australia, Queensland, and New South Wales. The highest temperature was recorded in Marree, South Australia, at 46.2°C, followed by Windorah in Queensland at 46.1°C, and Smithville Outpost in New South Wales at 45.4°C.
Temperature Readings Across the Region
The heat was not limited to these three states, as numerous readings between 43°C and 43.7°C were recorded right across the southern half of the Northern Territory, including at Alice Springs and Yulara, near Uluru. The heat also made its way to the northwest corner of Victoria, where the tiny town of Walpeup hit 40.1°C, marking the state’s first 40-degree temperature to date in spring 2025. This is notable, given that the season has been relatively cool compared to the long-term average in most parts of Victoria. The temperature readings across the region are a testament to the widespread nature of the heat event.
The Role of Severe Tropical Cyclone Fina
So, how did Severe Tropical Cyclone Fina help fuel this heat event? According to Weatherzone meteorologist Ben Domensino, TC Fina drew vast amounts of heat from the warm surface waters of the Timor Sea, which have been 30°C or higher near the Top End coastline. This heat was then transported into higher levels of the atmosphere, where it moved further south before descending over the Australian continent under the influence of an upper-level high pressure system. As Domensino explained, "As the air that was ejected into the upper-atmosphere moved south, it lost a lot of the moisture it began with but retained its potential temperature.” This process, known as adiabatic warming, caused the air to warm up as it descended towards the ground over central Australia.
Previous Heat Events and Future Forecast
This Monday has actually been the second day of extreme heat in outback regions, with Birdsville in Queensland’s Channel Country reaching 46.7°C on Sunday. This was just two degrees short of the statewide spring record. The interior heat is expected to dissipate on Tuesday, with some of it tracking towards the east coast. As a result, cities like Sydney and Brisbane can expect high temperatures in the coming days. Sydney is expecting a maximum of 36°C on Wednesday, while Brisbane is in line for a similar maximum on Thursday, with the chance of storms on what will be a very steamy and uncomfortable day. The heat event serves as a reminder of the extreme weather conditions that can occur in Australia, and the importance of staying informed about weather forecasts and warnings.
Conclusion and Outlook
In conclusion, the near-record-breaking temperatures in Australia’s interior are directly related to Severe Tropical Cyclone Fina, which drew vast amounts of heat from the warm surface waters of the Timor Sea and transported it into higher levels of the atmosphere. The heat event is expected to dissipate on Tuesday, but not before bringing high temperatures to cities like Sydney and Brisbane. As the weather continues to evolve, it is essential to stay informed about the latest forecasts and warnings to stay safe and prepare for any extreme weather conditions that may arise. By understanding the role of Severe Tropical Cyclone Fina in fueling this heat event, we can better appreciate the complex relationships between weather systems and the importance of monitoring weather patterns to predict and prepare for extreme weather events.
