Singapore air quality turns unhealthy across 4 regions as PSI climbs
Haze from fires in Indonesia drifted towards Singapore, with dry weather forecast to keep air quality under pressure in the coming days
On September 14, Singapore's air quality deteriorated across four out of its five regions, reaching unhealthy levels as measured by the PSI. The southern region became unhealthy at 10 pm, with a 24-hour PSI of 104. The central region recorded the highest PSI reading of 136. Among the four regions, the central area first entered the unhealthy range at noon after experiencing moderate readings for four days.
The eastern and western regions crossed the unhealthy threshold at 4 pm, registering PSI levels of 101, which subsequently increased to 119 and 114. The northern region remained in the moderate range, with a PSI of 94 at 10 pm. The shift in wind direction, moving from the southeast to east-southeast, facilitated the transport of smoke from Indonesian fires towards Singapore.
Smoke plumes from Kalimantan and parts of southern Sumatra drifted across the island, with some haze also originating from southern Sumatra and other regions in Kalimantan. Additionally, haze impacted parts of Sarawak, Peninsular Malaysia, and southern Vietnam, with monitoring stations reporting air quality ranging from moderate to unhealthy.
The National Environment Agency (NEA) anticipates that dry weather will prolong the haze situation over the coming days. Winds are expected to continue blowing from the southeast to east-southeast, potentially keeping Singapore exposed to the haze emanating from nearby fires. The 24-hour PSI is projected to range from high-moderate to mid-unhealthy levels over the next day.
NEA has been issuing daily haze advisories since September 4, when Singapore's PSI first entered the unhealthy range since 2023. The unhealthy PSI range spans from 101 to 200, with readings from 201 to 300 classified as very unhealthy, and anything above 300 being hazardous. For now, the recommended precaution is to monitor the PSI closely, particularly before engaging in extended outdoor activities.
Haze can fluctuate based on wind patterns, making it essential to stay informed to make better decisions.
