Background
Since early September, Singapore has experienced repeated spikes in the Pollutant Standards Index (PSI) as smoke from fires in Sumatra and Kalimantan drifts over the city‑state. The central region recorded multiple unhealthy readings, with the highest 24‑hour PSI of 192 on Oct 9.
The haze has impacted public behaviour: ActiveSG stadiums and swimming pools saw a 12% decline in weekly attendance, and golf clubs reported a 20% drop in golfers. Parents and seniors are especially cautious, cancelling classes and opting for indoor workouts.
The National Environment Agency monitors the situation and forecasts thundery showers that may temporarily improve air quality, but dry conditions in the source regions suggest the haze could persist.
Questions people ask
What PSI level is considered unhealthy?
Readings above 100 on the PSI scale are classified as unhealthy, meaning the general public should reduce prolonged or intense outdoor activities.
Can I still exercise outdoors during haze?
You can, but health experts recommend limiting intensity and duration, especially for activities like running or pickleball that increase breathing rates.
Will the haze improve later today?
The NEA forecast thundery showers in the afternoon, which may lower particulate levels temporarily, but overall PSI is expected to stay in the unhealthy range through the evening.
