Thick fog shrouds Brisbane and southeast Queensland

Ben Domensino, Wednesday July 10, 2024 - 10:27 AEST

A thick fog developed over southeast Queensland last night, with visibility reduced to less than 200 m at Brisbane Airport early this morning.

A combination of light winds and plentiful atmospheric moisture created ideal conditions for fog to develop across a broad area of southeast Qld on Tuesday night.

As the sun rose on Wednesday, fog could be seen stretching from Brisbane to Warwick and there were also patches visible across the Darling Downs and into the NSW North West Slopes and Plains.

Wednesday morning’s fog reduced visibility to about 190 m at Brisbane Airport shortly before 6am local time. Visibility was even lower further west, dipping below 130 m at Archerfield and getting to 110 m at Amberley in the early hours of Wednesday morning.

Fog is defined as a dense mass of small water droplets suspended in the air near the ground where visibility is reduced to less than one kilometre. Fog is caused when the air temperature cools to the dew point, which causes airborne water vapour to condense into small liquid droplets.

The thick fog prompted a road weather alert from the Bureau of Meteorology, due to reduced visibility making road conditions more dangerous than usual. The fog also slowed ground movement at Brisbane Airport and caused delays to some flights.

Wednesday’s fog may linger until around lunch time in parts of Qld and NSW, although most of it will clear up as temperatures climb during the morning.

Fog is likely to return to parts of eastern Australia on Thursday and Friday mornings.
