More grim news after city cops drenching
Following a weekend drenching, Sydneysiders are likely in for yet more rain this week. Those in the Harbour City can expect a thunderstorm on the coast and up to 15mm of rain on Monday. This comes after more than 40mm of rain fell across the city at the weekend. The Bureau of Meteorology rain gauge at Sydney Airport recorded 25.2mm in the 24 hours to 9am on Sunday, and another 15.6mm since. The rain stretched to Bellambi near Wollongong on Sunday night, with 14.5mm falling between 6pm and 10pm. Following Monday's showers, Sydney is forecast to potentially see a shower or two on Tuesday and Wednesday, with steady maximum temperatures in the high-teens. The rains are expected to move inland, hitting Wagga Wagga at the end of the week before clear skies plunge the inland city into frost on Sunday. Much of the rain on the radar for Monday is forecast to stay out over the ocean.

Melbourne could see up to 10mm of rain on both Tuesday and Friday. Canberrans will wake to frosts of -1°C on both those days as well, the forecast predicts. Brisbane is forecast for a mostly sunny week, while Perth could see up to 25mm of rain across Wednesday and Thursday. Adelaide and Hobart are in for drizzly weeks, while Darwin's dry season proves true to form. The Bureau is predicting a wetter than usual spring, with above average and potentially record-breaking rainfall for most of the eastern two-thirds of the country between August and November. 'Daytime temperatures for August to October are likely to be above average for northern, western, and southeastern Australia, with below-average daytime temperatures likely for the interior and some eastern parts of the country,' senior climatologist Lynette Bettio told NewsWire this week. 'This is consistent with the wetter-than-average forecasts and associated cloud cover,' Dr Bettio said. 'Night-time temperatures are very likely to be above average for most of Australia.'

Grim news for more than half of Australia
Much of Australia can expect a wetter than usual spring, with the Bureau of Meteorology predicting above average and potentially record-breaking rainfall for most of the eastern two-thirds of the country from August through November. Senior climatologist Lynette Bettio said for August to October, there would be 'likely wetter-than-average conditions' for most of the eastern two-thirds of mainland Australia. 'There is around an equal chance of rainfall being above, below, or near average for most of Western Australia and the far southeast,' Dr Bettio said. The bureau has highlighted a possible shift in the Indian Ocean Dipole (IOD), a key ocean temperature pattern strongly influenced by warming oceans and which greatly affects Australian weather. Warmer, wetter nights are forecast across much of Australia this spring. NewsWire / Damian Shaw Credit: News Corp Australia The coming months also look warmer than normal, especially overnight. 'Daytime temperatures for August to October are likely to be above average for northern, western, and southeastern Australia, with below-average daytime temperatures likely for the interior and some eastern parts of the country,' Dr Bettio said. 'This is consistent with the wetter-than-average forecasts and associated cloud cover. 'Night-time temperatures are very likely to be above average for most of Australia.' Across much of the eastern half of the country, there's also a high chance of unusually warm nights. 'For August to October, waters around much of Australia are forecast to remain warmer than average to the north, south, and east,' Dr Bettio said. The Indian Ocean Dipole plays a key role in shaping Australia's spring rainfall outlook.

There's also an increased risk of unusually high rainfall, in the top 20 per cent of historical records, for parts of eastern Queensland, NSW, southeastern South Australia, and northern Victoria. This period also marks the transition from the dry to wet season in northern Australia, typically bringing higher humidity, more storms, and regular showers. But not every region will share in the rain, with below-average totals more likely in western parts of Western Australia and southwestern Tasmania. Experts predict wetter-than-average conditions for much of eastern Australia this spring. NewsWire / Damian Shaw Credit: News Corp Australia While the IOD, a climate driver that can strongly influence rainfall, is currently neutral, the bureau expects it to shift into a negative phase from August to November before returning to neutral in December. This phase often boosts rainfall over southern and eastern Australia, though without a La Nina in the Pacific, the wettest possible outcomes are less likely. July 2025 recorded the warmest sea surface temperatures for the month since records began in 1900, continuing a run of record or near-record warmth since mid-2024. These warm oceans can help feed moisture into weather systems, increasing rainfall potential. Warmer sea surface temperatures continue to influence Australia's seasonal weather patterns.

More sustained falls will be needed to break long-term dry spells. 'In summary, we're likely to see a wetter-than-average August to October for most of the eastern two-thirds of mainland Australia, roughly equal chances of above or below-average rainfall for most of Western Australia and the southeast, and above-average daytime and night-time temperatures for most of the country,' Dr Bettio said.
