You might have noticed a burning smell hanging around eastern Singapore lately. The scent is most noticeable at night, and it has left many people wondering if there’s a fire nearby. The good news: official air quality readings show PSI and PM2.5 levels are still comfortably in the “good” range.
So, since the numbers are fine, what gives? From sources to preventive measures, here’s everything you need to know about the haze-like event:
Where is the smell coming from?
According to the National Environment Agency (NEA), the smoky smell in Singapore comes from vegetation and peat fires in the region, particularly in eastern Johor. These fires release gases called volatile organic compounds (VOCs), which can be detected by the human nose even at very low concentrations. Calm winds at night trap the gases near the ground, making the smell more noticeable, while north-easterly winds have carried the odorous smoke into eastern areas.
Why does the air smell smoky even when PSI and PM2.5 readings are normal?
PSI and PM2.5 track specific particles and pollutants in the air, but VOCs aren’t included. Our noses are sensitive enough to detect VOCs at extremely low concentrations, so the air can smell smoky even when pollution levels are technically “good.”
Where in Singapore does it get worse, and why?
Eastern areas, including Tampines, Bedok, and the East Coast, have reported the strongest smells. This is because prevailing north-easterly winds carry smoke and odorous gases from nearby fires directly over the east, while calmer winds at night allow the smell to linger closer to the ground.
Can I still go out?
For most people, the smell is just a nuisance. But those with asthma, allergies, or sensitive airways may experience irritation of the eyes, nose, throat, or lungs. Even low levels of VOCs can trigger reactions in sensitive individuals. Preventive inhalers, nasal sprays, or staying indoors during strong-smell periods can help. Doctors suggest keeping indoor air clean with purifiers too, and limiting exposure during calm evenings if the smell bothers you.
To be safe, avoid long periods of outdoor activity, especially in the evening when the smoke lingers.
