Thick morning fog across a wide part of Adelaide has delayed arrivals and departures at the airport, at West Beach.
The weather bureau said the fog rolled in across the northern and western suburbs and reached the airport about 7:00am.
All departures were on time until about 8:30am, but delays started as the fog thickened.
Visibility was down to about 180 metres after 9:00am but the fog was expected to clear by mid-morning.
Intending travellers were advised to check the airport's website or contact individual airlines for the latest information.
