What you need to know
Avoid strenuous outdoor activities when PM2.5 is above 56 µg/m³.
Vulnerable groups should stay indoors and keep windows closed.
N95 masks will be distributed to eligible residents if PSI exceeds 200.
Schools may modify or cancel outdoor activities; preschools must stop them if air quality worsens.
The exact duration of the haze episode and whether PSI will reach the hazardous (>300) level are not yet confirmed.
Background
The National Environment Agency monitors air quality using hourly PM2.5 and 24‑hour PSI readings. On Oct 10, central Singapore recorded a PM2.5 of 151 µg/m³, the first high‑band reading of the season, while PSI values stayed between 118 and 168, all classified as unhealthy.
Haze originates from forest‑fire smoke in southern Sumatra and Kalimantan. Prevailing east‑southeasterly or southerly winds carry the smoke toward Singapore, maintaining elevated pollutant levels despite occasional local showers.
The government’s Haze Task Force, comprising 28 agencies, has pre‑planned actions such as mask distribution, setting up air‑conditioned shelters, and adjusting school and sport activities if air quality deteriorates further.
Questions people ask
What health advice does the NEA give during unhealthy haze?
Healthy people should limit prolonged outdoor exertion; vulnerable groups should stay indoors and avoid outdoor activities altogether.
Will schools close because of the haze?
Schools remain open unless the next‑day PSI forecast exceeds 300, at which point closures may be announced around 8 pm the previous day.
How can I obtain an N95 mask?
Eligible Singaporeans—such as seniors, CHAS cardholders, and those with medical conditions—can collect masks at People’s Association venues or via vending machines at transport hubs.
