A thick fog has blanketed Sydney this morning, causing flights delays and some diversions.
Light winds in Sydney pushed the fog from the western suburbs — where it was initially thickest — towards the city and eastern suburbs, including Sydney Airport in Mascot.
Recent rain has been a major contributor, increasing the moisture required for fog formation.
The ample moisture, light winds and low temperatures produced a blanket of fog that reduced visibility to just a few hundred metres in many Sydney suburbs.

Reports suggest visibility at the airport has dropped below 500 metres at times — low enough to cause flight delays and even some diversions.
Passengers posting on social media were reporting flight delays of two hours.
The fog is expected to clear in the morning.
The Bureau of Meteorology has also issued a surf and swell warning for coastal activities such as rock fishing, boating, and swimming.
Sydney is expected to reach a top of 18 degrees today.
