Air quality in Singapore saw a notable improvement on October 26 as PM2.5 levels returned to the normal range, alleviating the haze that has affected the region in recent weeks. At 6 p.m. that day, the hourly PM2.5 readings, which gauge fine particulate pollution, ranged from 28 to 40 across Singapore’s five regions. Meanwhile, the 24-hour Pollutant Standards Index (PSI), which evaluates overall air quality based on six key pollutants, remained in the good-to-moderate band with readings between 67 and 74.
This improvement brings relief to residents following days of hazy conditions. The National Environment Agency (NEA) has forecasted a moderate PSI range of 60 to 90 for October 27. While smoke haze was detected over Kalimantan, the agency has assessed that the possibility of it affecting Singapore is low due to the expected northeasterly or southeasterly winds and forthcoming showers.
Looking ahead, variable winds and more showers are anticipated on October 28 and 29. The wet weather is expected to help suppress hotspot activity and mitigate the risk of smoke haze returning to the island.
Authorities advise that residents, especially children, the elderly, and individuals with pre-existing health conditions, should minimize outdoor activities if air quality levels were to reach unhealthy thresholds. These precautionary measures aim to protect vulnerable groups from potential health impacts associated with poor air quality.
