Thick pillows of fog quilted parts of the city on Friday morning, capping off a week of misty mornings in areas across the capital.

Low-lying cloud curled over the Australian War Memorial while Black Mountain was completely swallowed by white fog.

Weatherzone meteorologist Tristan Meyers said what we are seeing is the result of a high-pressure ridge laying across eastern Australia, in particular over NSW and Victoria.

"What that is doing is bringing light winds and fairly clear skies and those conditions, particularly in the shoulder months leading into winter are indicative of fog forming in the early mornings," Mr Meyers said.

"What happens is the temperature drops overnight and in the evening and once it reaches a certain threshold, the water vapour starts condensing out of the air and fog begins to form.

"It looks like temperatures fell to around seven, eight degrees early on Friday morning and that was low enough to create a rather thick blanket across the Canberra region."

Canberra Airport in particular was affected, Mr Meyers said.

"There's a runway out there, honest!" Tony Breeds tweeted from the airport.

Despite the misty starts for much of this week, next week should be much clearer.

"Looking further ahead, we're going to see a trough moving throughout the region with an accompanying front, and what this is going to do is cause winds to pick up a little bit, they're not going to be crazy gusty but it's going to be just enough so fog isn't going to form on those days," Mr Meyers said.

"Looking ahead at Saturday or Sunday, we have winds becoming a little bit stronger and cloud forming as well as some showers. The showers may make it so in the late evening you get some fog, or in the early morning, but it doesn't look like a full return to those conditions."

What you can expect is a bit of drizzle, he said.

"It looks like we'll have a few showers on Saturday although it'll be a mostly sunny start to the day but further on we'll see a few isolated showers pick up, a few heavier pockets in there but fortunately not too much, 5 to 10 millimetres in some areas but generally 1 to 3 millimetres.

"Then on Sunday we could get the odd shower and storm but they're most likely to stay around the Brindabellas with a low chance of anything to actually hit Canberra and the city," Mr Meyers said.

"Further ahead some light showers possible but these are lighter than previous days and then a ridge will develop after that which should bring mostly dry conditions."
