The ACT Emergency Services Agency warned Canberrans to expect a thick smoke haze over the city on Monday.
Forecast weather conditions were likely to result in smoke from fires in Victoria being blown across the ACT region overnight, a spokesperson said.
Acting ACT chief health officer Moira McKinnon said the smoke was affecting the air quality of the ACT and surrounding regions.

“Fine smoke particles are known to affect the human breathing system," Dr McKinnon said.
"These particles can cause a variety of health problems, such as itchy or burning eyes, throat irritation, runny nose and illnesses such as bronchitis.”
She said people with asthma, other chronic respiratory and cardiac diseases should not perform vigorous exercise and should stay inside if affected by the smoke.
“If you or anyone in your family is experiencing symptoms that may be due to bushfire smoke exposure, seek medical advice from your local doctor. Anyone experiencing difficulty breathing or chest pain should seek urgent medical attention by calling triple zero for an ambulance."
Dr McKinnon said the smoke may persist in the ACT for several days.
The smoke was visible on the capital skyline from early on Monday and could be easily smelt around the ACT.
Meanwhile, more ACT remote area firefighters have been sent to Victoria to relieve crews fighting fires at Cann River.
The five additional ACT Rural Fire Service volunteers will take over from crews who have been working in the area since Monday.
A spokesperson said the Remote Area Fire Team will work alongside their interstate counterparts to establish containment lines, while the returning firefighters are expected in Canberra on Tuesday.
