After sweltering in hot and humid conditions, Sydneysiders can expect cooler weather on Tuesday and Christmas Day after a southerly change hits the city.
The mercury hit 36C in Sydney on Monday afternoon and nudged 38.7C at Coonamble in the state’s central west.
But the Bureau of Meteorology said a southerly change due to hit late on Monday would bring cooler conditions to much of NSW on Tuesday and on Christmas Day.
‘‘The southerly change moving through this afternoon will see the warm temperatures dropping down to the low 20s,’’ Bureau forecaster Francois Geffroy said..
‘‘That should continue with those lower temperatures into Christmas.’’
He said on Christmas Day Sydney’s CBD could expect a temperature of around 25C, with 26C forecast for the city’s west.
There was a chance of rain on both Christmas Eve and Christmas Day, he said.
‘‘It’s potentially a shower or two for both those days,’’ Mr Geffroy added.
He forecast temperatures would start to rise again on Boxing Day, with a chance of a thunderstorm.
The NSW Rural Fire Service (RFS) said it would decide on Monday afternoon if a total fire ban would be declared for Tuesday.
RFS spokesman Joel Kershaw said if the forecast remained unchanged a total fire ban wouldn’t be needed.
‘‘That will be assessed this afternoon,’’ he told Macquarie Radio.
