Flights have resumed at Adelaide Airport after heavy fog caused delays and diversions this morning, and blanketed a wide sweep of the city and surrounding suburbs.

The spectacle captured the attention of morning commuters, as the fog lingered well into the morning, reducing visibility and causing the CBD skyline to disappear from view at popular vantage points.

"The fog this morning was amazing. Everything looked so ethereal," one social media user wrote.

"Never seen fog like it in Adelaide. An eerie drive in to work," another said.

A Singapore Airlines flight scheduled to land in Adelaide at 8:00am was diverted to Sydney, while Qantas and Virgin Australia flights from Brisbane landed late after circling over the Murray Mallee while waiting for the fog to lift.

Regional flights to and from Whyalla, Olympic Dam, Mount Gambier, Port Lincoln and Ceduna were also delayed.

Bureau of Meteorology duty forecaster Bonnie Hazelgrove said the fog extended right across Adelaide, from Noarlunga in the south to Elizabeth in the north.

"We're seeing thick fog and visibility down to 100 metres at Adelaide Airport, which is probably one of the worst ones I've seen in my five years as a forecaster," she said.

"So not a great morning to be out on the roads unfortunately — if you are out and about allow a bit of extra time and make sure to turn your headlights on so everyone can see you."

She said the fog could "hang around for a while".

Westerly winds could blow more fog back over the coast in the afternoon.

"The beach might not be the nicest place to be today and will be cold and foggy if that eventuates," Ms Hazelgrove said.

SA Police earlier issued a road weather alert for Adelaide.

"Reduced visibility in fog will make road conditions dangerous throughout the Adelaide area this morning, and near the coast this afternoon," police said.

Fog also hit regional areas yesterday and today, including in Port Pirie.

ABC Radio Adelaide listener Michael said he had driven down Greenhill Road for 50 years from his Ashton home and it was the foggiest he had seen.

"It actually had me pull over and take in the view this morning," he said.

However, he said skies were clear over the eastern suburbs.

"People waking up in Burnside are thinking 'what cloud, what are you referring to, it's beautiful here'," he said.

ABC Radio Adelaide presenter Peter Goers said he could not see the Glenelg jetty from his beachside apartment.

"You can't even see where the sea starts and the sand stops. The visibility would be about 30 metres," he said.
