Singapore air quality remains in the good-to-moderate range
On Monday, Singapore’s 24-hour PSI readings were 64 to 84, in the good-to-moderate range.
Hourly PM2.5 readings across the country’s five regions were also within the normal band.
Air quality has stayed in the good-to-moderate range since Oct 25, after an earlier spell of haze.
Smoke plumes were observed in Kalimantan, while showers fell in parts of Singapore on Sunday.
Singapore’s National Environment Agency expects showers in the region to keep haze subdued, with the 24-hour PSI forecast to be moderate on Monday.
The agency advises checking PSI forecasts for outdoor plans and hourly PM2.5 readings for immediate activities; when hourly PM2.5 is elevated, healthy people should reduce strenuous outdoor activity, while vulnerable groups should avoid it.
Singapore’s 24-hour Pollutant Standards Index was in the good-to-moderate range on Monday, Nov 2.
At 8am, 1-hour PM2.5 readings across the five regions were in the normal band, ranging from 26 to 44.
The PSI readings ranged from 64 to 84, while the 24-hour PSI was forecast to be between 51 and 80 on Monday.
