Visibility was at eight to 10 kilometres at Bendigo Airport about 9am on Tuesday.
It stood at just 2.5 kilometres on Monday morning.
Bendigo's visibility had improved over the course of Tuesday morning, standing at five kilometres on earlier readings.
Ten kilometres or more is normal on a clear day, 1.5 kilometres or less is considered hazardous.
Bureau of Meteorology forecaster Steven McGibbony said a thick cloud and low inversion trapped air on Monday, but winds had picked up again on Tuesday.
He said there was still plenty of smoke in the atmosphere, with no significant flush out expected until a change came through on Friday.
Victorians have been warned that those most vulnerable to the effects of smoke are people with respiratory conditions, pre-existing heart or lung conditions, those under 14, over 65 and pregnant women.
Paramedics report a 51 per cent increase in people reporting breathing problems.
Breathing problem calls increased from an average of 187 per day to 282 across the state on Monday.
Ambulance Victoria Acting Director of Emergency Management Justin Dunlop said he thought the increase was largely due to smoke.
