Extreme heat is headed for New South Wales, and Sydney’s western suburbs may see temperatures in the low 40s. This marks the first major heat event of the season, with the heat stretching from Western Australia’s northwest all the way to Parramatta. Alongside the heat, a severe fire danger warning covers large parts of NSW, while a cooler change is anticipated by the weekend.
Bottom line: NSW residents should brace for hot conditions, but relief is on the way as a cold front arrives later in the weekend. The Bureau of Meteorology (BOM) describes this as the first taste of what could be a hot summer for much of the country, according to its long-range outlook.
Heat climbs across the country
Severe heatwave warnings are in place for wide swaths of the country, including the NSW coast from east of Cooma to Newcastle on Saturday, along with Sydney and Wollongong. BOM senior forecaster Jonathan How notes that parts of the NSW coast could see temperatures up to 15C above average.
"Saturday will be the peak across Sydney and eastern New South Wales," How said. "Sydney is forecast to reach about 37C in the city, with the low 40s in the western suburbs. It will be extremely hot along the coast as well."
In contrast, the hottest temperatures are expected in Western Australia’s Kimberley region, where extreme heat could persist into next week. Fitzroy Crossing is predicted to hit 46C on Sunday and Monday, BOM reports. How adds that storm activity may develop in the middle of next week, helping to ease the heat but without a major monsoon system forming.
Extreme fire danger for Sydney, Hunter, Illawarra
The BOM also warns of extreme fire danger across much of NSW, with a risk of dry lightning in parts of the state on Saturday. Nine areas, including Greater Sydney, Greater Hunter, and Illawarra/Shoalhaven, are under total fire bans for the weekend.
Rural Fire Service spokesperson Ben Shepherd highlighted a bushfire near Bulahdelah on the Mid North Coast as a particular challenge, noting winds could shift back to the northwest. On Friday, the blaze was at emergency warning level and blocked the M1. There are concerns about Milsons Gully near Sandy Hollow in the Upper Hunter as heat and drought conditions persist.
Heat wave spreads nationwide; Perth records hottest start to summer
Heat has swept across the country all week, with Perth experiencing a record-hot start to summer at 39C on Monday. By Thursday, a northwesterly airstream pushed the heat southeast to Adelaide and Melbourne, both reaching 35C, their warmest days since March.
Cool change and storm risk ahead
Saturday is expected to be the last day of extreme heat for southern Australia, with cooler air arriving in the coming days. Western Australia and Victoria have already seen milder conditions, while Victoria and parts of Tasmania may receive showers from a cold front. Tasmania could see snow down to about 700 meters on Saturday evening.
Severe thunderstorms are possible in eastern Victoria and parts of southern NSW, including the Illawarra region, on Saturday. By Sunday, the cooler air should spread across Sydney and the Central Coast, reaching northern inland NSW. However, southern Queensland may experience only a partial front,
Forecasts also indicate that severe storms could develop from Saturday afternoon into Sunday across northern NSW, with potential for damaging winds and heavy rainfall from Newcastle to the Tablelands. Sunday is likely to bring more widespread severe thunderstorms.
Heat stress may signal a hot summer ahead
This week’s heat event could mark the beginning of an exceptionally hot summer for Australia. The BOM’s long-range outlook for December to February favors above-average daytime and nighttime temperatures across most of the country. The forecast includes larger chances of unusually warm maximums in Victoria, Tasmania, eastern Queensland, northern WA, and the Northern Territory, along with likely unusually warm nights in many regions.
With ongoing dryness in some areas, fire and emergency services warn that several parts of the country could enter a season of heightened fire risk. The AFAC seasonal bushfire outlook highlights increased fire risk across southern WA, NSW, and large portions of Victoria later in the season.
