Sydney swelters through hottest day since 1939

"It looks like it's the highest temperature recorded in the Sydney area in 80 years", Jacob Cronje, a Senior Meteorologist with Weatherzone, said.

The top temperature had initially been forecast as 40C (104F), but temperatures at the Sydney International tennis tournament exceeded that by 10am, forcing players off court.

Temperatures were expected to remain in the high 30s to early 40s Celsius Monday and the fire ban would be continued, it said.

More than 200 weather records were broken nationwide during the last summer, with intense heatwaves, bushfires and flooding plaguing the December 2016-February 2017 season.

"43 degrees but probably 50 on court when started. I think it's 1st time in my career I retired a says it all", the world number 11 tweeted.

Sydney was reportedly the hottest place on earth on Sunday with Penrith taking out the title of the hottest part of the city on Sunday, reaching 47.3C just after 2.30 pm.

"Meantime with the arch rivalry between the Australian and English cricket teams being played-out in the Ashes Test Series at the Sydney Cricket Ground (SCG) meteorologists advised fans to "#slipslopslapseekslide".

The hottest temperature ever recorded in the area was 47.8 Celsius degrees (118.04 Fahrenheit) in 1939, the Bureau of Meteorology for the state of New South Wales (NSW) said.

A total fire ban means no fires can be lit in the open and all fire permits are suspended.

Several blazes had already been recorded on Saturday, and a number of properties were destroyed in the states of Victoria and South Australia.

Experts have warned that land and sea temperatures have been affected by climate change, leading to more extreme weather conditions.
