Canberra has experienced its coldest morning of the year so far and an unusually cold start to the cooler months.

Temperatures dropped below freezing on Monday morning for the first time since November, reaching minus 1.7 degrees at Canberra Airport and minus 2.6 degrees at Tuggeranong.

On Saturday, Canberra had a top of 9 degrees, which is the earliest start to the season in 31 years.

Forecaster Sean Carson says the last time it was this cold so early in Autumn was in 1983.

He says Canberra was the colder than anywhere else in the country this morning.

Around the region, Braidwood dropped to zero while Goulburn recorded minus 2, as did the Snowy Mountains.

Mr Carson says more freezing temperatures are expected this week.

“The cold front that swept across on the weekend did bring a dusting of snow across the Snowy Mountains,” he said.

“Looks like we will have some light frost almost every morning for the next seven days, it’s that time of year.”

“But followed by a beautiful sunny afternoons, with top temperatures around 16 degrees for the second half of the week.”
