45C possible in Australia this weekend

Temperatures are set to soar across the Australian outback this weekend, with parts of South Australia possibly hitting 45°C on Sunday. A large mass of hot air is currently building over WA, causing temperatures to reach the low forties in the state’s north. In the Pilbara, which is no stranger to hot weather at this time of year, Mardie reached 43.5°C on Monday and had already surpassed 43°C by 2pm AWST on Tuesday. Image: Clear skies over WA are allowing heat to build. This heat will spread towards the south in the middle of this week, causing temperatures to reach close to 40°C at Eucla on the south coast of WA. Another more intense round of heat will then sweep across central and southern Australia on the weekend as northerly winds strengthen ahead of an approaching low pressure trough. Some forecast models suggest that temperatures will reach around 44 to 45°C in SA this weekend, with the hottest day currently expected to be on Sunday. The maps below show one computer model’s prediction for the maximum temperatures on Saturday and Sunday. Image: Forecast maximum temperature on Saturday, October 18, 2025. Image: Forecast maximum temperature on Sunday, October 19, 2025. The highest temperature ever recorded in Australia during October was 46.9°C at Port Hedland in 2002, while SA’s highest October temperature was 45.4°C at Oodnadatta in 1995. Temperatures could challenge the SA record this weekend, with parts of the state’s North West Pastoral District forecast to reach 45°C on Sunday. The last two times anywhere in Australia reached 45°C this early in October were in 2014 and 2004. The upcoming heat will also help to cause High to Extreme fire danger ratings in parts of southern Australia over the coming days.

Prolonged Top End heatwave as Australia’s most reliable cloud appears

Two interesting meteorological phenomena are occurring this week in the Northern Territory’s Top End: an ongoing heatwave, and the seasonal appearance of "Hector the Convector" – a storm cloud that develops over the Tiwi Islands north of Darwin at roughly the same time every day for months on end. The heatwave While most southerners would consider the Top End hot year-round, and while October and November are on average the hottest months for maximum temperatures at many locations, the region will be even hotter than usual this week. From Wednesday onwards, Darwin is expected to reach 35°C or 36°C for at least the next six days. The October average maximum is 33.4°C. Away from the sea breeze in the NT’s third-largest population centre of Katherine, three hours southeast of Darwin, temperatures should nudge 40°C by the end of the week. The October average maximum is 37.6°C. Minimum temperatures at the above locations will also be a degree above average or slightly higher in the week ahead, prompting the BoM to declare a low intensity heatwave at present – with the heatwave forecast rising to severe and even extreme at some locations by the end of the week. This is based on the BoM’s definition of heatwaves as a period of three or more consecutive days during which maximum and minimum temperatures are "unusually hot". Hector the Convector Image: "Hector the Convector" can be seen forming over the Tiwi Islands in this three-hour radar and satellite loop to 2:50pm (ACST). Thunderstorm clouds form when warm, moisture-laden air rises into higher levels of the atmosphere, then cools as it gets higher. This causes water vapour to condense into liquid drops, producing cloud. Hector the Convector ("convection" means the vertical rising of air) was named by pilots during World War II who used it for navigation when flying near the Top End, noting how reliable it was in its appearance. When sea breezes flow over the Tiwi Islands from all directions and clash in the elevated interior of the islands, Hector forms as the converging breezes force air to rise, creating a column of warm and moist air that produces a towering cumulonimbus cloud. Melville Island – the largest of the Tiwi Islands – cannot quite be seen from Darwin as it’s approximately 60 km north of the city. However, Hector can often be spotted above the island with its towering cumulus clouds, while air passengers flying in and out of Darwin Airport often get a good glimpse too.

US Climate Prediction Center declares La Niña – what this means for Australia

A La Niña advisory has been issued by the US Climate Prediction Center (CPC), indicating that La Niña conditions have emerged in the tropical Pacific Ocean and are expected to continue for the coming months. What is La Niña? La Niña is one of three phases of the El Nino-Southern Oscillation (ENSO), a coupled ocean-atmosphere phenomenon that occurs in the tropical Pacific Ocean. The three phases of ENSO are La Niña, El Niño and neutral. When La Niña is occurring, cooler-than average water sits near the surface of the central and eastern equatorial Pacific Ocean, while easterly trade winds flowing over the tropical Pacific Ocean become stronger than usual. This pattern typically results is in enhanced cloud and rainfall over the western tropical Pacific region, including parts of Australia. Image: Typical ocean and atmospheric components of La Niña. La Niña Advisory declared by US Climate Prediction Center A La Niña advisory was issued late last week by the US CPC. The advisory stated that “La Niña conditions are present and favored to persist through December 2025 - February 2026, with a transition to ENSO-neutral likely in January-March 2026.” The CPC’s La Niña definition is based on sea surface temperatures in the central equatorial Pacific Ocean being at least 0.5°C cooler than average, and an expectation that this region will remain below this threshold for at least three consecutive months. In addition to this ocean component, there also needs to be clear signs of an atmospheric response above the tropical Pacific Ocean for La Niña to be declared by the CPC. According to the advisory, these atmospheric changes are currently being observed. “Collectively, the coupled ocean-atmosphere system reflected La Niña conditions,” the CPC says. La Niña not yet recognised by BoM The CPC’s definition of La Niña differs from that of Australia’s Bureau of Meteorology (BOM). While the CPC has declared that La Niña is underway, the BoM does not agree and still classifies the ENSO as being in a neutral state. The Bureau has slightly different La Niña thresholds to the CPC, requiring more intense and prolonged ocean cooling in the tropical Pacific Ocean before a La Niña can be declared. Therefore, while conditions have now met the CPC thresholds for declaring La Niña, they aren’t yet sufficient for the BoM to follow suit. According to the Bureau of Meteorology, “the El Niño–Southern Oscillation (ENSO) remains neutral. “The Bureau's model currently predicts the tropical Pacific is likely to meet La Niña levels briefly during spring, before returning to neutral by summer.” The current La Niña signal in the Pacific Ocean may not be strong enough for long enough for the BoM to declare La Niña. If one is declared, it is likely to be weak and short-lived. How will this impact Australia's weather? Moderate-to-strong La Niña events that occur during late spring and early summer typically enhance cloud and rainfall and suppress daytime temperatures over large areas of Australia, particularly northern, central and eastern parts of the country. However, the influence of weak or borderline La Niña episodes is less predictable. Image: Average October-to-December rainfall during nine moderate to strong La Niña events. Source: Bureau of Meteorology Image: Average October-to-December maximum temperatures during nine moderate to strong La Niña events. Source: Bureau of Meteorology It is clear that a La Niña-like pattern has become established in the Pacific Ocean in recent weeks. However, this pattern is currently expected to be short-lived and relatively weak, which means it may not have a strong influence on Australia’s weather in the coming months. Other climate drivers, including the Indian Ocean Dipole (IOD) and Southern Annular Mode (SAM), and abnormally warm sea surface temperatures closer to Australia, are expected to have a stronger influence on the Australian climate over the next few months.
