PSI forecast to be in ‘good to moderate’ range on Oct 26; showers over S’pore may reduce haze
Showers are expected over Singapore and the vicinity, with winds expected to blow from the south-west or west.
Singaporeans may experience a brief respite from the haze on October 26, as air quality is expected to improve to a "good to moderate" range, according to the latest forecast from the National Environment Agency (NEA). The haze advisory issued by NEA on October 25 indicated that the air quality index (PSI) is projected to fall between 70 and 100, with values ranging from zero to 100 considered good to moderate and above 100 as unhealthy.
The NEA attributes the expected improvement to the presence of showers over Singapore and its surrounding areas on October 26. Winds blowing from the southwest or west are anticipated to decrease the likelihood of smoke haze affecting the city-state. This trend is expected to continue on October 27 and 28, further enhancing the reduction in haze levels.
Hourly PM2.5 readings across all five regions in Singapore returned to normal levels in the early hours of October 25, with the 24-hour PSI showing a more gradual decline. Although smoke haze was observed in Kalimantan, it did not reach Singapore. At 7pm on October 25, PSI readings in the "good to moderate" range were recorded in the north (94), south (91), east (99), and central (97) regions.
The western part of the island still fell within the unhealthy band at 107, while PM2.5 readings ranged from 22 to 31, falling within the "normal" range.
