Millions in NSW to be lashed by rain, strong winds as system looms off east coast
Bureau of Meteorology senior meteorologist Sarah Scully said it's a 'wet outlook for eastern parts of Australia over the coming days'.
The bureau's latest figures estimate up to 9mm of rainfall for Sydney on Thursday, with a rise of up to 15mm on Friday.
A developing coastal trough is swinging through, re-energising rain and shower activity across inland Queensland and northern NSW, according to Ms Scully.
'Now that is expected, or is bringing, some patchy rain and showers that are forecast to extend into inland parts of NSW later today and also into tomorrow,' she said.
While the worst of the weather will move away by Wednesday, Ms Scully said an onshore flow was expected to keep some showers hanging around in NSW — meaning the wet and windy weather may linger until end of next week.
'There are early indications of a low pressure system in the NSW coast on Friday, which has the potential to bring moderate to heavy rainfall and strong winds on Monday,' she said.
'The greatest impacts will be concentrated about the central and mid-north coast of NSW.'
Ms Scully says the onshore flow is being 'driven by a ridge of high pressure' causing southern and eastern winds to bring moisture off the Tasman Sea onto NSW and Queensland and further amplified by upper trough to create enhanced showers all week.
Rainfall totals from the bureau estimate up to 9mm in Sydney on Sunday before a steep rise to 20mm on Monday.
Sydney metropolitan and the Hunter District, in particular, are in for a drenching.
With wet weather on the horizon, temperatures in NSW have plummeted, ranging between the cusp of the teens and low 20s with cloudy skies.
The showers also continue in Queensland, with temperatures set at the mid 20s and moderate to high chances of rain for the rest of the week.
In the country's west, Perth residents are in for much sunnier days and temperatures rising to the mid- to high-20s throughout the week, with light winds during the day.
Darwin dwellers can expect sunny skies all week, with temperatures going up to the mid-30s with little chance of rain.
South Australians should look out for cloudy mornings all week, with Adelaide temperatures at the 20s with medium chance of showers.
A wintry chill is well and truly setting in to the country's south, with overnight temperatures in Melbourne and Hobart dipping below 10C by Friday.
Daytime temperatures in both capitals are expected to hover near 17C for the rest of this week.

South-east Queensland rain set to ease for weekend, after days of steady rainfall
Parts of south-east Queensland have received double the average rainfall for August with wet weather set to ease from this afternoon, giving way to drier and warmer conditions for the weekend. The Bureau of Meteorology (BOM) said most people would be unfamiliar with so much rain falling at this time of year. "To get a really widespread dose of rain over the course of winter is a little bit more unusual, and it has rained in many areas across the south east," senior meteorologist Angus Hines said. In just three weeks, the Gold Coast has already received more than 100 millimetres of rain, compared with the August average of 52mm. During intense rainfall on Thursday, more than 100mm of rain fell in parts of the Gold Coast. BOM weather stations at Burleigh Waters and Elanora, on the city's southern side, recorded 111mm and 136mm respectively. The Sunshine Coast Airport saw 47mm of rain fall on Wednesday, while the Yandina Creek weather station, also on the Sunshine Coast, recorded 93mm. The Darling Downs, Granite Belt, and Southern Border ranges have also been soaked, receiving 40mm in parts. Although there could be further showers on Friday morning along the coast from Bundaberg to the New South Wales border, Mr Hines said the wet weather was drying up. "That's likely to continue into the weekend. Saturday and Sunday are both looking nice, with clear days across the majority of the state on Sunday afternoon. "Perhaps we'll see a coastal shower or two for some spots, but that looks pretty minimal … nothing to stress about." Beaches along the south-east could have 2-metre easterly swells on Friday, but those too will ease by Saturday. According to the bureau, as well as drier conditions, much of the state can expect things to heat up over the weekend. Mr Hines said warmer conditions would kick in as the rainband and cloud cleared from the south-east. Temperatures were expected to hang around the low 20s today, before hitting mid-20s over the weekend. "We're looking at … above-average [temperatures] pretty much statewide on Saturday and Sunday," Mr Hines said. Mr Hines said in some places through the north, west and central districts, temperatures could be anywhere from 4 to 6 degrees Celsius above average. "So perhaps a little taste of spring for some areas in the last week or so of winter," he said. Further north, strong south-easterly winds can be expected on the far north coast, with a strong wind warning in place for Cape York Peninsula and Cooktown coast

'Warmest weather in months' coming after record-breaking NSW rain
After weeks of persistent rain, parts of the NSW coast have now recorded their wettest August in 126 years. In what is historically a relatively dry and sunny time of year, Sydney has enjoyed only five days without rain since July 30. The unseasonably rainy August has triggered multiple flood events, and continues to be one of the wettest years on record for the state's central and northern coast. And while heavy showers will linger along the coast on Friday, weather modelling offers hope of relief next week with brighter and warmer weather forecast. With August being one of the driest months of the year on the NSW coast, this week's major rain event has broken records. In the 24 hours to 9am on Thursday, Port Macquarie was drenched by 148 millimetres — this is the city's heaviest August rain on record with data back to 1871. Observatory Hill, Sydney's official weather station, received 82mm in 24 hours, the highest in 18 years for August. As rain continued to tumble down through Thursday, Sydney's monthly total climbed above 350mm against an average of 80mm, the fourth highest for August in 167 years of data. Sydney's wet spell actually started in late July and over the past 24 days, rainfall has been measured in the city on 79 per cent of days, compared to a long-term average of rain on 33 per cent of days. Following well-above average falls in five previous months this year, Sydney's total rain in 2025 has now reached around 1350mm, more than 100mm above the annual average, and more than 400mm above normal to this point in the year. Several other notable totals around the state this month include (to 6pm Thursday): The above figures will climb even higher during the coming days, with potentially heavy showers still brushing the coast on Friday and a few lighter showers also lingering through the weekend. This month's rain has been extraordinary, not only for its persistence, but also the intensity. Typically, in late winter there is a westerly flow across south-east Australia, which favours rain on the inland side of the Great Dividing Range while impeding rainfall in the east. However, this August an easterly flow has blown on most days, a direction far more commonly seen during the warmer months. With Tasman Sea humidity blowing onto the NSW coast into a wintertime environment of polar air, the result has been August rainfall up to five times the average. But why has the wind blown from the east in August? The answer lies in the pressure pattern in the Tasman Sea. So far this month, the surface pressure between Tasmania and New Zealand has been as much as 13 hectopascals above average — that's a huge deviation from normal and since winds blow anticlockwise around high-pressure systems in the Southern Hemisphere, the abnormal pattern has not just slowed down winter westerlies, but completely reversed them. The infamous August westerlies are about to return, opening a window for the sodden NSW coastline to dry out. The change back to typical late winter weather will arrive as a series of powerful cold fronts approach from the west early next week. These fronts will work together to push a stubborn Tasman Sea high away from Australia, creating a path for westerly winds from Monday, which should become the established flow right through next week. The arrival of a westerly airstream will not only bring clearer skies to the NSW coast, but also lift maximum temperatures. By Tuesday, Sydney's suburbs are forecast to reach 23 to 24 degrees Celsius, the warmest weather in three months.
