Bureau of Meteorology forecaster Katarina Kovacevic said the weather will be stable.

The bureau is expecting a top of 13 degrees and partly cloudy conditions on Monday, with the relatively balmiest days forecast on Tuesday and Friday with tops of 15 degrees.

"All week it's looking like they'll be dry days, so no rainfall. Either mostly sunny or partly cloudy for all of the working week," Ms Kovacevic said. "Kind of Groundhog Day really, from Monday through to Friday."

The bureau is expecting some shower activity over the capital on the weekend, with rain more likely on Sunday, but said it was still too early to tell.

"At this stage we're expecting a front to move through the ACT on the weekend," Ms Kovacevic said.

Down at the Snowy Mountains, Ms Kovacevic said it will be much of the same, with no snow expected over the top of the ski fields.

But the cold temperatures have kept the snow guns firing. At Perisher Resort, snow guns had been working for over 100 hours as of midday on Sunday.

"These consistent cold temperatures provide the ideal conditions for our snowmaking team to blast the snow guns," a Perisher spokesman said.

The ski fields had seen "on-and-off" snow flurries throughout Sunday, the spokesman said, but no decent snowfall.

Likewise at Thredbo, a spokesman said snow guns had been helped by the negative temperatures.

"We can see a cold front set to arrive on July 1 expecting to bring a solid snowfall to the resorts," the spokesman said.

At the South Coast, the bureau was predicting maximums of 18 degrees for most of the week. Ms Kovacevic said the water temperature was 17.4 degrees on Sunday evening, with two-metre swells predicted for the next couple of days and south to south-easterly winds.

"From about Wednesday onwards [swell is] about one to one-and-a-half metres," she said.
