Record-breaking autumn heatwave over south-east Australia hints at growing trend
ABCIn short: A heatwave rolling over south-eastern Australia has seen temperature records tumbling. The four-day heatwave saw several March records fall, with both day and night-time temperatures in some places rivalling, or even exceeding, those experienced during the peak of this year's summer. She said it was also being helped along by an upper-level high-pressure system over south-eastern Australia — a feature that's not able to be seen on the weather map – which further enhanced the heat. "If you've got those higher night-time temperatures, you're less able to, so you still have a sweating requirement to get rid of body heat," Professor Jay said. "We are seeing a lengthening of the heatwave season basically everywhere in the world, inclusive of south-east Australia," Dr Kirkpatrick said.
