Sydney weather: How hot it will get this week

A heatwave washing across Australia will break temperature records for September and pummel millions of Australians until Wednesday.

The Bureau of Meteorology has released a ‘severe heatwave’ warning for the NSW south coast, warning punishing low to mid-30s temperatures will continue until midweek.

‘These temperatures are above average by around 10 to 15 degrees and persist for an unusually prolonged period for this time of year,’ the bureau states.

The bureau believes the ‘very uncommon’ September heat will likely break records for the most number of days in a row above 30C until a cold front later on Wednesday eases conditions.

Temperatures in Sydney will hit 33C on Tuesday and 34C on Wednesday.

The bureau predicts a maximum temperature of 34C to hit Brisbane on Thursday.

Health officials are warning that babies and the elderly face severe health risks from the heat.

NSW Health executive director of health protection Jeremy McAnulty said people should minimise heat exposure and reduce their physical activity outdoors in the next few days.

‘Don’t wait until you’re thirsty before drinking water,’ he said.

‘It’s best to try and avoid the heat of the day by staying indoors and keeping curtains and blinds shut early.
