Warmest October on record for Sydney, Brisbane
Sydney and Brisbane just had their warmest October on record, despite a relatively cool end to the month. A surge of cold air caused temperatures to plummet in eastern Australia earlier this week. In Brisbane, the temperature only reached 22.2°C on Tuesday, while Sydney’s maximums remained below 18°C on both Tuesday and Wednesday. These chilly days, which were about 4 to 5°C below average for this time of year, were a cold drop in an ocean of warmth this month. Sydney and Brisbane, and many areas in between, just experienced their warmest October on record based on maximum temperatures. Sydney’s average maximum temperature for the month will come in at around 26.6°C. This is more than 4°C above the monthly average and warmer than the previous October record of 26.2°C from 1988. Brisbane’s average maximum temperature in October will come in at around 29.4°C, more than 2°C above average and comfortably higher than the previous October record of 28.7°C from 1918. Many other areas in Queensland and New South Wales also broke their maximum temperature records this month. This included new state records when Birdsville, Qld reached 46.1°C and Wanaaring, NSW reached 44.9°C on October 21. Image: Modelled daily maximum temperature over Australia on October 21, 2025, showing a pool of very hot air over the eastern inland. Why was October so warm in eastern Australia? A rare sequence of stratospheric warming episodes occurred high above Antarctica in September and October. These abrupt changes in temperature disrupted the Southern Hemisphere's polar vortex, which affected weather patterns over Australia during October. One of the big effects from this stratospheric phenomenon was a relentless flow of warm and dry westerly winds over eastern Australia throughout most of October. These westerly winds carried hot air from central Australia across Qld and NSW, causing weeks of unseasonably warm and dry weather. The map below shows that air temperature around 1.5 km above the surface was, on average, about 3 to 4°C warmer than usual over a large area of central and eastern Australia.

Source: NOAA Another factor that helped cause this month’s record-breaking heat was a lack of cloud and rain over large areas of the country. Despite the presence of a strong negative Indian Ocean Dipole – a climate driver than typically boosts cloud and rain over Australia in spring – northern, central and eastern Australia only saw limited rain during October. This was because of the strong influence of the stratospheric warming event, which counteracted the IOD. Climate change is also likely to have played a role in this month’s record heat. The average maximum temperature over eastern Australia has increased by around 1.84°C since 1910.

Late spring ice cliffs on Australian alpine creeks
Australia's iconic Snowy River didn’t earn its name without good reason. But "Icy River" would be a more accurate description right now, as high ice walls still line the banks of the upper reaches of the Snowy and nearby creeks and streams – even as November is upon us. The reason these spectacular snowdrifts are still lining Australia’s highest alpine waterways a month out from summer is because 2025 was a relatively good snow season at higher elevations. Image: Snowdrifts caving in under their own weight as the running waters of alpine creeks undercut them. Source: Phil Campbell. While Australia’s lowest ski resorts struggled with a meagre snowpack and an abbreviated ski season, deep snow accumulated at the highest elevations of the mainland high country. At an elevation of 1830m, Spencers Creek in NSW is the highest point at which Snowy Hydro has taken consistent snow depth readings through winter and spring since 1954. This year, Spencers Creek’s peak snow depth was 220.4cm in early September The ice wall effect in the lead image of this story is caused by drifting snow. On ridges and wind-scoured parts of the mountains, snow disappears quickly at the beginning of spring or even in late winter. But in protected areas, snow accumulates until it is many metres deep. Even after a moderate snow season, snow patches persist into spring and early summer on the lee slopes of Australia’s highest peak Mt Kosciuszko and nearby summits. Anyone who has hiked Kosciuszko in summer (and 100,000 people do it year) could tell you that.

Snow patches can also be seen well into December most years on the highest peaks of the Victorian Alps like Mt Bogong and Mt Feathertop. But because the NSW alpine region is a few hundred metres higher than Victoria’s, and because its topography is slightly less rugged overall, the highest alpine valleys in NSW retain deep snowdrifts along the creeks well into spring too.

Interestingly, October 2025 was slightly warmer than average in the high country, with a rapid melting of the remnant winter snowpack. "A lack of moisture for cold fronts to turn into top-up snow has also contributed to rapid snow loss during October," Weatherzone meteorologist Ben Domensino explains. Despite the swiftly diminishing snow cover, the ice walls remain along some creeks – for now. Meanwhile the graph for Spencers Creek is just about locked in for season 2025, although it hasn’t quite hit rock bottom yet – with an average of 4.9cm on October 29. That measurement doesn’t include the deep ice walls on the fringe of the creek.

Days of severe thunderstorms ahead for Qld, NSW
A multi-day outbreak of severe thunderstorms will hit parts of Queensland and NSW over the next six days, culminating in a huge rainband sweeping over eastern Australia early next week. A series of upper-level troughs passing over eastern Australia will cause a period of unstable weather between now and Tuesday. This volatile six-day period will include daily rain and severe thunderstorm activity over parts of Qld and NSW, including numerous storm days around both Brisbane and Sydney. Thursday and Friday – storms building up Thursday will feature showers and thunderstorms in both states, mainly about the ranges and some areas of the coast. There may be a few severe thunderstorms over central and southeast Qld and northeast NSW in the afternoon and early evening. Friday will be more active, with thunderstorms possible over most of NSW and eastern Qld, and even extending down into Vic. Severe thunderstorms are again most likely to occur in central and southeast Qld and northeast NSW on Friday, although there could also be some severe storms in southwest NSW and northern Vic. Brisbane and western parts of Sydney could see thunderstorms on Friday afternoon or evening, which may disrupt Halloween activities. Be sure to check the radar and thunderstorm warnings before going trick-or-treating on Friday. Saturday and Sunday – violent thunderstorms likely Thunderstorms will become more intense on Saturday as the atmosphere becomes increasingly unstable in response to an upper-level trough. Storms could develop early in the morning over eastern parts of NSW and Qld on Saturday, before becoming more widespread and intense during the afternoon into the evening. Saturday’s storms will be most active between central eastern Qld and central NSW, which could include both Brisbane and Sydney. Supercell thunderstorms are possible on Saturday, and isolated tornadoes can’t be ruled out. Image: Lifted index (LI) for late morning on Saturday. LI values below zero (blue shading) are indicative of an environment that is conducive to thunderstorms. This map shows that LI values will be lower than –6 in parts of NSW and Qld on Saturday, showing that the atmosphere will be very unstable and ripe for intense thunderstorms. Sunday’s thunderstorm activity will be less widespread as a brief reduction in atmospheric instability causes storms to mostly become confined to southeast Qld and far northeast NSW. Monday and Tuesday - Rainband developing with more storms A potent upper-level cut-off low will move across southeastern Australia early next week, causing areas of rain, thunderstorms and blustery winds across parts of Qld, NSW, the ACT, Vic, Tas, SA and the NT. A broad northwest cloudband ahead of the trough will also spread rain across much of central, eastern and southeastern Australia. This system will cause a dynamic mix of weather in multiple states on Monday and Tuesday, likely including heavy rain, severe thunderstorms, damaging winds, hail and snow. Some areas of eastern Australia have a chance of seeing thunderstorms every day for the next six days, with severe storms possible each day. Image: Forecast accumulated rain during the next seven days combined. Be sure to keep a close eye on the latest forecasts and warnings in your area over the next six days and check the radar to see if storms are about before heading outdoors.
