There is nothing like morning fog to re-inforce that summer is long-gone, and Sydney certainly had this drilled in this morning.

Many days of humid winds across New South Wales was just one of the ingredients that helped cause areas of fog state-wide, and in Sydney in particular. Shorter days, weakening winds and clear night skies also lended a hand.

Richmond, in Sydney’s west, saw visibility drop to 100 metres by 6:30am as the foggy soup thickened. Even at 8:30am observers were not able to see more than 500 metres into the distance.

A bit closer to the CBD suburbs like Canterbury and Homebush experienced areas of fog as well, with visibility dropping to 400 metres. Some of this eventually spilled over into the city centre, gifting morning cummuters with a glorious vista as the rising sun sent spears of gold into the misty air.

The fog started to lift significantly from around 9am, although more susceptible suburbs like Richmond saw a slight delay.

Tomorrow morning is still a chance for more fog with light winds and clear skies near-certain.
