The Australian city of Sydney has experienced its hottest weather in 79 years with temperatures in the region hitting as high as 47.3oC (117F).

In Penrith, west of Sydney, residents sweltered as the town bore the brunt of the heat.

Severe fire warnings were issued for the greater Sydney area and total fire bans were put in place across the city.

Temperatures fell short of the scorching heat to hit the area in 1939, when the mercury reached 47.8oC.

The sweltering temperatures reached in Penrith were confirmed by the Bureau of Meteorology.

ABC reported that one charity, Mission Australia, helped transfer homeless people to hospital for treatment while taking others into shelters to avoid the heat.

About 7 000 properties across New South Wales were left without electricity, partly because of the heat, the Sydney Morning Herald reported.

At the Sydney Cricket Ground, England’s batsmen struggled on the hottest day on record for a Test match in Australia.

Players participating in the Sydney International Tennis Tournament were forced off the court at mid-day by the event’s organisers after temperatures courtside exceeded 40oC.

France’s Kristina Mladenovic apologised after she retired midway through her match against Australia’s Ellen Perez because of the heat.

The fire bans in place in the greater Sydney area were imposed to reduce the risk of wildfires, which are common during Australia’s arid summers.

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

In September 2017, Australians were warned to prepare for a dangerous bushfire season after one of the driest winters on record.

More than 200 weather records were broken across Australia between December 2016 and February 2017, with heatwaves, bushfires and flooding throughout the country’s summer season.

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

Tomorrow’s forecast for Sydney, perhaps unsurprisingly, is for more hot weather – and some rain later in the day.
