All times are Singapore time (UTC+8).
Checked every 10 minutes. Official data is generally updated hourly.
Regional readings do not measure your exact street or indoor air. The 24-hour PSI shown is an observed index, not a forecast for the next 24 hours.
The 24-hour PSI expresses air quality as an index. Its averaging period differs from 1-hour PM2.5, so their numbers cannot be compared directly. For tomorrow’s plans, refer to the official 24-hour PSI forecast and corresponding health advisory.
Read the official explanation ↗The 1-hour PM2.5 reading measures fine-particle concentration over the past hour, in µg/m³. During haze, it helps you interpret current air quality and plan immediate activities. A short-term change does not describe the whole day.
See the latest official guidance ↗Photos, distant views and visibility cannot replace measured air-quality data. Winds can carry smoke from regional forest fires. Dry weather, rainfall and wind direction influence haze. Check the readings and official updates before heading out.
Understand how haze forms ↗The health effects of haze depend on a person’s health, pollution levels, and the duration and intensity of outdoor activity. Reducing outdoor activity and physical exertion can help limit the effects of exposure.
Older people, children and those with chronic heart or lung conditions should take particular care. Seek medical attention if you feel unwell. Refer to official health advisories when planning activities.
