Update on Hotspot and Haze Situation

4.           Heavy showers fell over many parts of Singapore today. As at 6pm, the 1-hr PM2.5 concentration readings were 16 – 25 µg/m³, in (Band 1, Normal), and the 24-hr PSI was 63 – 81, in the Moderate range. Moderate to dense smoke plumes were observed in some parts of Kalimantan and southern Sumatra.

5.           For tomorrow to Thursday, prevailing winds are expected to blow mostly from the east or southeast. Showers are forecast over Sumatra, Kalimantan, Singapore and the surrounding region, which could help keep the haze situation suppressed.

Activity Guidelines

7.         The health impact of haze is dependent on one's health status, the PSI level, and the length and intensity of outdoor activity. 

8.        For updates, visit our haze microsite (www.haze.gov.sg), the NEA website (www.nea.gov.sg), MSS website (www.weather.gov.sg), mobile app (myENV) or follow us on NEA Facebook (www.facebook.com/NEASingapore). For information on the distribution of hotspots detected over the past fortnight in the region, please refer to the ASEAN Specialised Meteorological Centre (ASMC) website at http://asmc.asean.org.

Areas with lighter smoke haze are not indicated as they cannot be clearly discerned from satellite imagery. The full extent of the hotspot and smoke haze situation could not be determined due to cloud cover.
