Based on the last few hours of NEA 1-hour PM2.5 readings, not a forecast. Haze can change quickly, so check again before heading out.
The level that matches today's worst region is highlighted. Advice summarised from MOH, NEA and HealthHub.
| Status | 24-hr PSI | 1-hr PM2.5 (µg/m³) | What it means for kids |
|---|---|---|---|
| 🟢 Outdoor play OK | 0–100 (Good/Moderate) | 0–55 (Band I) | Normal activities. |
| 🟡 Best to stay indoors | 101–200 (Unhealthy) | 56–150 (Band II) | Minimise prolonged or strenuous outdoor exertion. |
| 🔴 Stay indoors | Above 200 (Very Unhealthy/Hazardous) | Above 150 (Band III–IV) | Minimise outdoor activity (PSI 201–300); avoid outdoor activity above PSI 300. |

Check the live colour for your region above. Green (24-hr PSI 100 or below and 1-hr PM2.5 55 µg/m³ or below) means normal outdoor play. Yellow (PSI 101–200 or PM2.5 56–150) means best to stay indoors. MOH advises children to minimise prolonged or strenuous outdoor exertion at this level. Red (PSI above 200 or PM2.5 above 150) means stay indoors.
NEA and MOH classify a 24-hour PSI of 101–200 as Unhealthy, 201–300 as Very Unhealthy and above 300 as Hazardous. For children, the official advisory is: 101–200 minimise prolonged or strenuous outdoor physical exertion; 201–300 minimise outdoor activity; above 300 avoid outdoor activity. Children with chronic lung or heart disease should avoid prolonged or strenuous outdoor exertion from PSI 101 and avoid outdoor activity from 201. MOH haze advisory
MOE says schools should modify or, if necessary, suspend physical and outdoor activities when haze conditions pose risks to students' well-being, taking reference from NEA's readings and MOH's health advisories. Schools use the 24-hour PSI forecast for planning and adjust based on the 1-hour PM2.5 reading, classrooms have air purifiers, and students who are unwell or have lung or heart conditions are excused from outdoor activities and PE. Follow your school's Parents Gateway notices and MOE's official announcements for decisions on your child's school. Sources: MOE, MOE haze management, NEA.
The 24-hour PSI is NEA's overall air quality index and moves slowly. The 1-hour PM2.5 reading shows fine haze particles right now and is useful for deciding about the next few hours. Haze Buddy uses whichever of the two is worse.
Haze Buddy reads NEA's latest 24-hour PSI and 1-hour PM2.5 for North, South, East, West and Central Singapore from data.gov.sg, updated hourly, and maps them to green, yellow or red using NEA's published health advisory bands. It is general guidance only, not medical advice.
MOH says the key precaution for children is to follow the haze health advisory when planning outdoor activities. There are no international certification standards for children's masks; MOH says the AIR+ Smart Mask can be used, only where necessary, by children without heart and lung conditions, provided it keeps a well-fitted seal at all times. N95 masks are not needed for commuting to school or indoors. Take a mask off if your child feels uncomfortable, and ask a doctor if your child has a heart or lung condition. Source: MOH.
