Hazy conditions persisted overnight with the three-hour Pollutant Standards Index (PSI) reaching 94 at 9am on Sunday.
The haziness was due to smoke haze from Singapore's surrounding region, blown in by the prevailing winds, said the National Environment Agency (NEA).
At 7am on Sunday, the one-hour concentrations of PM2.5 was 47 - 54 ug/m3, and the 24-hr PSI was 90 -104, in the Moderate to Unhealthy range.
For Sunday, the prevailing winds are forecast to be light and variable in direction. Thundery showers are expected in the afternoon, said NEA.
