Sydney baked on Saturday, 5 September 2026. The Bureau of Meteorology said the city was headed for about 33°C, nearly 13°C above the September average.
Authorities issued a total fire ban for the Greater Sydney Region and rated bushfire danger as extreme — the second-highest rating. Hot, dry air and strong winds were the reason, not a single large blaze in the city.
What the weather bureau warned
The Bureau said fresh to strong, gusty northwesterly winds would develop during the morning. Combined with dry, unseasonably warm air, those winds would lift fire danger across Greater Sydney.
The forecast path was steep: about 27°C at noon, then 33°C by 1pm. At Sydney Airport, the temperature was already 28.6°C at 11:30am — more than 7°C above the September mean maximum.
The first days of September were on track to match the midsummer average of 26.4°C at Observatory Hill. That would be the warmest start to spring since the station opened in 1858.
The fire ban, in practice
A total fire ban means no fires in the open. Electric barbecues may still be used. Gas barbecues are allowed only if a responsible adult is in charge, combustible material is at least two metres away, there is an immediate and continuous water supply, and the barbecue is within 20 metres of a dwelling or in an approved picnic area.
The NSW Rural Fire Service told residents to act on a bushfire survival plan, watch rfs.nsw.gov.au and bom.gov.au, and call 000 in an emergency. The danger rating was forecast to ease back to moderate in the coming days.
Why this heat arrived so early
A strong El Niño is driving a hotter, drier spring across southern Australia. Climate change is also making extreme heat and fire weather more common in a country that already lives with bushfire.
In January 2026, firefighters in the southeast battled blazes that destroyed homes, cut power, and burned large areas of bush. Saturday’s warning is that combination arriving in the first week of spring: heat, wind, and dry fuel.
