Perisher ski resort recorded 30cm of snowfall overnight, bringing the two-day total to 65cm after a snowstorm hit the area.

The resort posted on social media on Monday morning saying the area is covered in white, and skidoos had to be dug out of the snow.

A Bureau of Metrology spokesperson said precise snow amounts are hard to measure in a ski field where there is fake snow but it is not unusual for snow to occur past winter.

"We may not see any more events of where we get this much snow, but having said that, spring is a fairly variable time of year weather wise. So there is still a potential to get snow, some snow not just throughout September but even into October or November," he said.

However, the amount of snow will be "significantly less" and will melt more quickly.

"It's difficult to say definitively but I suspect we probably won't see this much snow happening again during the season as much as we've just had over the weekend. But it's not unheard of to see these sorts of snowfalls in September, it's just as a variable time of the year weather-wise."

The nearby Thredbo resort was also hit by the snowstorm, with 53cm of snow over the weekend.

Thredbo general manager Stuart Diver said, "The 53cm of fresh snow has arrived at the perfect time to freshen the snow cover up for the September school holidays and the final weeks of the snow season."

"Skiers and snowboarders are showing big smiles this morning as they enjoy great springtime conditions on the mountain."

Despite the additional snowfall, both resorts are still set to close on October 3.

The ACT and NSW are in for a wetter than normal spring and summer as another La Nina event was declared by the bureau earlier this month.

Above average rainfall is forecast to continue until early 2023 as Australia experiences a third consecutive year of La Nina.
