Australians face everything from sweltering heat to heavy rain over Christmas, with some major cities hitting above 30 degrees over the holiday period.
Weatherzone meteorologist Craig McIntosh told Yahoo News Australia a high-pressure ridge building on the east coast would clash with warmth inland, which has tropical moisture, heading east.
“So, that means the two will be acting against each other,” he said.
“One will stop the other one from being too cool. The other will stop the other from being too hot.”
Bureau of Meteorology senior forecaster Dean Narramore told the ABC the lead up to Christmas might contain some flash flooding though, particularly in South East Queensland and northern parts of NSW.
NSW’s Christmas weather
Residents in Sydney can expect some light showers on Christmas Eve and Christmas Day.
Conditions will be partly cloudy with tops of 26C both days and lows of about 17 to 19, according to the Bureau of Meteorology. Expect up to about 1mm of rain on both days.
Boxing Day might also see light showers in Sydney.
Towns across the NSW South Coast can look forward to similar conditions.
In Northern NSW, Byron Bay could potentially receive up to 15mm of rain on Christmas Day, with the temperature forecast to reach a maximum of 24C.
Areas including Tenterfield and Glen Innes could receive a wet start to the week too with heavy rainfalls of up to 20mm on Sunday and 60mm.
ACT’s Christmas weather
Meanwhile in Canberra, temperatures will be in the high 20s on Christmas Eve and Christmas Day.
