The 24-hr PSI in eastern part of Singapore is 140 and the 1-hr PM2.5 is 115 at 8am.

The air quality in Singapore deteriorated on Oct 9, with the central region hit the hardest.

The PSI level there was 177 at 11am, a new high for 2026, while the PM2.5 reading crossed over into high pollution levels at 152.

The central region’s PSI reading had already set a new 2026 record of 173 at 10am, and 170 at 9am, breaking the previous high of 167, recorded in the same area on Sept 29.

Air quality is considered unhealthy when the PSI – a 24-hour rolling average of six key air pollutants – is in the range of 101 to 200.

PSI readings across all five regions in Singapore have remained largely in the unhealthy range over the past 24 hours, with some areas dipping into the moderate range between 6pm on Oct 8 and 1am on Oct 9. Since 2am, all regional readings have returned to the unhealthy range.
