24-hr PSI
Highest in the South (90)
1-hr PM2.5 µg/m³
Best for planning the next few hours — it reacts faster than the 24-hr PSI.
Fine particles — the main haze pollutant from vegetation and peat fires. Elevated PM2.5 with a PSI above 50 is the typical haze signature.

About this adviceSource: NEA
Vulnerable persons include the elderly, pregnant women, children, and persons with chronic lung disease or heart disease.
Next few hours follows NEA's 1-hr PM2.5 guide, which is not intended to be prescriptive; short-term symptoms such as throat or eye irritation are expected to resolve after withdrawing from the exposure.
Planning for tomorrow: NEA advises using its 24-hr PSI forecast, published on haze.gov.sg when air quality is in the Unhealthy range. This card shows the advisory for the current 24-hr PSI.
- REDUCE
- do less
- MINIMISE
- do as little as possible
- AVOID
- do not do
- PROLONGED
- continuous exposure for several hours
- STRENUOUS
- involving a lot of energy or effort
