Fog will be back tomorrow
Bureau of Meteorology spokesman Jess Carey said Bundaberg had the prime set-up for fog.
"A fair bit of cloud around Bundaberg that cleared last night and with that clearing, it combined with some light winds," he said.
Mr Carey said there was quite a lot of moisture left at surface level ahead of a trough in the coming days. "When those three things combine, you have a perfect make-up for fog," he said.
"That could potentially be at the coast, it could be inland, it just depends wherever you've got those conditions lining up, as long as you've got those three things, you've got all the potential for fog."
Mr Carey said it looked to be foggy again in the morning.
"Tomorrow there is still a good set-up for it," Mr Carey said.
"We've got similar conditions forecast for tomorrow morning before some more cloudy conditions move into the area late tomorrow afternoon and evening.
"As soon as you've got those cloudy conditions it's fairly unlikely to see fog, it's still possible tomorrow but unlikely for Friday and into the weekend."
Mr Carey said the foggy conditions seen this morning were fairly normal for May.
"April to October tends to be our peak fog season in the southeast, but you can get fog in the middle of summer, so it's not unheard of to get fog any time of the year in Queensland," he said.
Mr Carey reported visibility at Brisbane Airport was down to 50 metres.
"It was relatively thick, but it hasn't caused any major disruption," he said.
He offered the following advice to motorists.
"Take a few kilometres off your speedo and turn you lights on, take the proper precautions for tomorrow morning," he said.
