The haze situation in Singapore continues to ease, with the Pollutant Standards Index (PSI) on Wednesday (28 October) expected to remain in the moderate range, similar to the previous day. Showers forecast over Kalimantan, Sumatra, Singapore and surrounding areas are expected to help suppress hotspots and haze, further improving overall air quality in the region.
The National Environment Agency (NEA) said on Tuesday (27 October) evening that Wednesday’s 24-hour PSI was expected to range from 60 to 90, within the moderate range.
Singapore experienced dry weather on Tuesday. As of 7pm, the 24-hour PSI across the island’s five regions ranged from 62 to 75, within the moderate range, with the highest reading in the west. One-hour concentrations of fine particulate matter (PM2.5) ranged from 21 to 34 micrograms per cubic metre, within the normal range.
The agency also forecast that winds would shift to blow from the east-southeast or south-southeast on Thursday and Friday. While these winds could carry smoke from southern Sumatra to Singapore, showers expected in the region should help reduce the risk of haze.
NEA reminded the public to refer to the PSI forecast and related health advisories when planning outdoor activities for the following day. For immediate outdoor activities, they can check the latest one-hour PM2.5 concentrations on the haze website (haze.gov.sg) or the myENV mobile app.
