Singapore air quality remains unhealthy as haze persists
Singapore's air quality remains in the unhealthy range due to smoke haze drifting from Sumatra and Kalimantan. The National Environment Agency expects these conditions to persist as dry weather continues in the source regions.
Why it matters
Persistent haze poses significant public health risks and highlights the ongoing regional challenge of transboundary air pollution in Southeast Asia.
Listen SINGAPORE – The air quality across the island remained largely unchanged on Oct 12, with the 24-hour PSI staying in the unhealthy range and the one-hour PM2.5 readings hovering between the elevated and high bands.
At 3pm on Oct 12, the PSI readings stood at 109 in the north, 117 in the south, 135 in the east, 149 in the west and 149 in the central region.
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.
Meanwhile, the one-hour PM2.5 readings have been fluctuating between the elevated and high bands.
At 3pm, the one-hour PM2.5 readings in the western and central regions deteriorated into the high range, which spans 151 to 250.
