The heatwave continues in New South Wales, with summer-like temperatures and summer-like fire danger.
On Thursday morning, there were 68 bushfires burning, 17 of them uncontained, as dangerous winds pick up strength ahead of a southerly change due later on Wednesday.
The NSW Rural Fire Service has declared a total fire ban in three regions: Greater Sydney, Greater Hunter, and Upper Central West Plains. Please click here for a reminder of the total fire ban rules.

Meanwhile the unprecedented September hot spell continues to break records both for high temperatures, and for the duration of unseasonably hot temperatures.
- We’ve already seen Sydney equal its hottest September temperature in over 100 years of records, while Sydney Airport exceeded the old record.
- This Wednesday, Sydney is likely to register back-to-back 34-degree days for the first time on record in September. Indeed it will be the first time the mercury has soared that high on any two September days.
- Penrith in the city’s outer west could give the September high temp record of 37.3°C a nudge. As we were writing this story at 10 am, it had already touched 31.7°C.
There have also been some extremely warm minimum temperatures in the current long-lasting heatwave.
- While Sydney’s minimum of 20.5°C just before 9 pm on Tuesday evening was not a September record, the night actually warmed after that.
- At 3 am on Wednesday, Sydney was sitting on 22.8°C while Darwin was just 22.3°C at 3 am local time.
It’s not often that Sydney would be warmer than Darwin in the middle of a September night, or the middle of any night in any month, which illustrates how much hot air has been pushed into eastern NSW this week.
But there’s NSW relief in sight…
A southerly buster will sweep northwards along the NSW coast later this Wednesday. The good news is it will cool things down significantly and effectively signal the end of the heatwave.
The bad news for fire authorities and people with property in fire-affected or fire-prone areas is that it will be a mostly dry change, with only light showers expected along parts of the coastal fringe.
Meanwhile the heat will edge its way into southeast Queensland on Thursday, bringing temps in the low-to-mid thirties to Brisbane and the Gold Coast, with the mercury reaching the mid-to-high thirties further inland in places like Ipswich.
