Temperatures in Sydney’s outer west peaked at 35C and 32C in the city on Monday before a cool change from the south-east.
Sydney and parts of New South Wales have sweltered through an “unseasonably warm” weekend, with temperatures climbing more than 10C above the September average, before a cool change swept much of the coast on Monday.
The early burst of heat, part of a classic “ spring rollercoaster ”, brought summery hot weather conditions to the state.
Weatherzone reported that a wave of heat swept across south-eastern Australia over the weekend, before the peak of the heat hit Sydney on Monday.
Sydney Observatory Hill reached a high of 32.7C at 10.40am, before temperatures plummeted by about 10C within a couple of hours, a Bureau of Meteorology spokesperson told Guardian Australia on Monday afternoon.
On Sunday, western suburbs recorded maximums of about 34C, while the city recorded 28.9C.
The spokesperson said temperatures were “unseasonably warm in many parts of the state”, generally sitting 6C to 12C above the September average.
“It was quite warm compared to the September average in Sydney, say, by more than 10C,” they said, noting the average September maximum for Observatory Hill is 20.1C, and 23.5C for Penrith.
On Tuesday, Sydney city temperatures will hover in the high teens, between 18C – 19C, before warming up to between 22C and 24C on Wednesday.
