The weather bureau says an extreme cold front has broken a series of low temperature records for Canberra, Goulburn and the Snowy Mountains.

The southern tablelands and Victoria's Alpine region have also been hit by the summer chill.

A rapidly moving cold front from Antarctica moved though Tasmania, Victoria, New South Wales and the ACT yesterday.

The icy and changeable weather delivered a low of -4 degrees Celsius and a dusting of snow to the Snowy Mountains.

Forecaster Sean Carson says the snow is unseasonable, but not rare.

"In fact, it was only three to four years ago they had a 20cm centimetre fall in January," he said.

In Canberra, the mercury dropped to 1.6C, eclipsing the record of 1.8C set in 1956.

Goulburn experienced -0.1C, beating the previous record January low of 1.4C.

The front has now moved east over the Tasman Sea.
