Singapore air quality improves as winds shift, but haze persists
SINGAPORE: Singapore’s air quality improved on Sunday as winds shifted to blow from the south, but lingering haze kept the 24-hour Pollutant Standards Index (PSI) in the unhealthy range of 106 to 186.
On Sunday, Singapore's air quality saw an improvement as winds turned to blow from the south, although haze continued to linger, keeping the 24-hour Pollutant Standards Index (PSI) within the unhealthy range of 106 to 186. According to the National Environment Agency (NEA), smoke haze from Kalimantan persisted, drifting towards the city-state.
The haze was also observed over Sumatra. As of 7pm, NEA data revealed that one-hour PM2.5 concentration readings fluctuated between 37 to 69, falling within the normal and elevated bands. The agency forecasted showers for tomorrow, along with winds coming from the south-southeast or south, which may restrict the movement of smoke haze from Kalimantan to Singapore.
However, some smoke haze from Sumatra could still drift towards Singapore. The NEA projected that the 24-hour PSI would range between 101 and 190 on Monday.
