Singapore is dealing with a return of haze, with air quality readings easing after earlier deterioration. The Straits Times reported on Friday, 11 September 2026, that the haze had come back and examined how the current episode compares with previous occurrences.
According to The Straits Times, air quality across Singapore stayed in the moderate range as the Pollutant Standards Index dropped below 100. CNA reported that conditions in central Singapore had returned to the moderate band.
Looking ahead, AsiaOne reported that the 24-hour PSI forecast for 12 September was expected to remain in the moderate to low unhealthy range. Singapore's National Environment Agency published a haze situation update dated 9 September 2026.
The reports do not specify the source of the current haze or the exact PSI values recorded. The Straits Times framed its coverage around how this episode stacks up against past haze events in Singapore, though the available summaries do not include those comparisons.
Haze in Singapore is typically linked to regional land and forest fires, and the NEA monitors PSI levels to guide public health advice. The agency's situation updates are the official reference point for air quality conditions.
What to watch next: whether PSI readings stay in the moderate band or climb back into the unhealthy range, and what the NEA's next situation update shows.
