Strange mist descends over Sydney, but there's a simple explanation

Fog isn’t something you usually associate with a Sydney summer, but on Monday a mysterious mid-morning mist descended over Sydney’s Bondi Beach, clouding the famous shoreline in low, dense cloud.

The clouds rolled in from the sea, prompting beachgoers to take to their camera phones to record the eerie haze.

It might have looked odd, but the NSW Bureau of Meteorology said there was a perfectly simple explanation as the fog continued to roll across Sydney into the afternoon, making it all the way to Sydney Harbour.

By mid-afternoon, the fog had rolled across Sydney’s coastline from the Northern Beaches to the Royal National Park on the city’s southern outskirts.

“While it’s not necessarily common to see fog in the afternoon, the current moist conditions over the sea are conducive to it,” BoM tweeted.

“Might hang around for a bit.”

Moist air, warm water and a lack of wind meant that the fog remained dense rather than breaking up.

It was cloudy, but not cold, with the city hitting a top of 28C.

Tuesday and Wednesday are predicted to be a comfortable 25C, but Thursday looks to be another humid day, with a predicted top of 32C.
