Hottest September day in years forecast in parts of south-eastern Australia as ‘spring rollercoaster’ sets in

Australians in the south-east are expected to experience the warmest September day in years, with temperatures rising 6C to 12C above average over the weekend. According to the Bureau of Meteorology, a cold front in Western Australia and a high-pressure system in the Tasman Sea are dragging warm, dry and sunny weather towards south-eastern Australia.

Coastal areas are expected to reach the high 20s while inland regions will extend into the low to mid 30s. In some areas, such as Sydney's western suburbs, temperatures are tipped to peak from 30C to 34C.

This rapid warming follows a polar blast earlier in the week, which dropped temperatures as much as 10C below average over south-east Australia. The region had also experienced frosty nights, with Goulburn reaching -7C at one point. The warm weather is expected to sweep through western South Australia on Saturday and the east on Sunday.
