Air quality in Singapore mostly unhealthy; PM2.5 elevated in four regions
The National Environment Agency said the 24-hour PSI was expected to be in the unhealthy band on Monday, ranging from 101 to 190.
Singapore's air quality remained mostly unhealthy on Monday, October 19, according to the 24-hour Pollutant Standard Index (PSI). The index ranged from 92 in the north to 139 in the west, with elevated PM2.5 readings in western, central, southern, and eastern regions. The PSI peaked at 230 at 10am, marking a new high for the haze season.
On Sunday, the PSI was unhealthy across most regions, but the western region was in the very unhealthy range from 8pm on Saturday. The National Environment Agency (NEA) forecasted showers and winds from the south-southeast or south, which may reduce smoke haze from Kalimantan. However, smoke haze from Sumatra could still drift towards Singapore, and winds are expected to turn east-southeasterly from Tuesday night, potentially bringing smoke haze from Kalimantan towards Singapore overnight.
The NEA advised vulnerable individuals to minimize prolonged outdoor activities when the PSI is in the unhealthy range and to wear an N95 mask or equivalent to reduce exposure to haze particles.
