Australian Weather

Today, 1:01AM UTC

Sub-zero minimum temperatures were recorded in seven of the eight Australian states and territories overnight, with only the Northern Territory failing to record a freezing temperature. On Wednesday morning, the coldest reading for each state and territory was: NT: Alice Springs 3.2°C SA: Yunta -0.9°C Qld: Applethorpe -1.1°C TAS: kunanyi/Mt Wellington -1.5°C WA: Newdegate -1.5°C ACT: Tuggeranong -2.8°C VIC: Mt Hotham -3.1°C NSW: Thredbo Top Station -6.5°C What caused the widespread overnight chill? These were not exceptional or record-threatening temperatures for midwinter, but they were still well below average in many locations. For example, Newdegate in Western Australia’s Great Southern region – which fell to -1.5°C overnight – has an average July minimum of 4.4°C and a record July low of -3.8°C.  Thredbo Top Station – which recorded Australia’s lowest reading of -6.5°C overnight – has an average July minimum of -5.1°C and a record low of -13.5°C. Minimums were cooler than average across a broad area of the country due to: Calm, clear, conditions caused by a strong high pressure system centred over southern SA A cold dry airmass lingering in the wake of a series of cold fronts which have now moved well out into the Tasman Sea Will the cold nights continue this week? The alpine region of NSW and Victoria can expect a string of nights well below zero lasting all the way through to the end of the week. That’s good for the snowmakers at the ski resorts.

We wrote yesterday about the impending period of very heavy rain likely in northern NSW, while several days of showers can be expected between Thursday and Monday for the stretch of the east coast from at least Sydney to Brisbane. While this rainfall event will be very much confined to the coast and adjacent ranges, the moist easterly flow will push a fair way inland, increasing the relative humidity which in turn will prevent the mercury from dropping too far overnight.

The map above shows precipitable water in the atmosphere and the predicted position of the high centred over South Australia on Thursday morning. Winds circulating anti-clockwise around the high will push maritime air to inland regions, even though rain is only expected near the east coast. Meanwhile in Western Australia, a cold front approaches the southwest. While it will introduce a cooler, moister airmass, minimums should generally be warmer than they have been in recent days at many locations due to the cloud and extra humidity.

A multi-day midwinter heavy rainfall event is looking increasingly likely for the North Coast of New South Wales and immediately adjacent areas, including just over the Queensland border. According to Weatherzone meteorologist Joel Pippard, four-day totals of 100-200mm are expected from Thursday through to next Monday, with isolated totals around 250mm, along a strip of coastline stretching roughly from Coffs Harbour to the Gold Coast. Falls should be heaviest along the northernmost reaches of the NSW coastline as the event kicks off on Thursday, with 24-hour totals of 60-120mm expected in the area around Lismore and Grafton from Thursday afternoon to Friday morning. Equally heavy totals could be recorded on Sunday around Coffs Harbour and the nearby Dorrigo Plateau. What will cause the heavy rain? The first ingredient for this impending spell of wet weather is a flow of moist air pushing onshore from the Tasman Sea, circulating around a high which will be centred over inland parts of southeastern Australia. The available moisture will be enhanced by sea surface temperatures in the Tasman Sea which are around 1°C higher than usual for this time of year away from the immediate coastal strip.  Image: Forecast synoptic chart for Thursday, July 16, 2026.

This set-up will fuel the heavy rainfall over the Northern Rivers and the northern part of the Mid North Coast.

The most severe weather from this system is expected to occur along the sections of NSW coastline and adjacent ranges already mentioned. While the Gold Coast could see heavy rainfall with potential flooding, Brisbane is only expecting showers from Thursday through to Monday, with no persistent heavy rainfall forecast. Like Brisbane, Sydney can expect a showery spell lasting four or five days, however it should also miss the heaviest rain in what is expected to be a fairly localised intense weather event.
