The overnight temperature did not drop below 25.3 degrees Celsius Saturday into Sunday in central Sydney, according to the meteorology bureau, making it the hottest November night since records began.

The temperature had already hit a scorching 30 degrees Celsius by 4:30 am Sunday, before reaching above 40 degrees for the second consecutive day.
