Looking at recent hourly PM2.5 readings…
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.
What to do today
The level that matches today's worst region is highlighted. Advice summarised from MOH, NEA and HealthHub.
🟡 Yellow day: keep it short and light
- Children should minimise prolonged or strenuous outdoor exertion: short, gentle play instead of sports or long outings.
- Check the 1-hour PM2.5 before going out; reduce strenuous activity for the next hour when it is in Band 2 (56–150).
- Close windows and doors when the air looks worse; drink plenty of water.
- Children with heart or lung conditions should avoid prolonged or strenuous outdoor exertion.
🔴 Red day: stay indoors
- Children should minimise outdoor activity (PSI 201–300) and avoid it above PSI 300 or when 1-hour PM2.5 is Very High (251+).
- Set up a clean-air room (below) and play indoors.
- Masks only where necessary for short trips, following MOH's advice for children (see FAQ).
🏠 Keep haze out of the home
- Close doors and windows when outdoor air is worsening; reopen them when it improves.
- Avoid indoor smoke such as cigarettes and candles.
- Mop or wipe dust instead of dry-dusting or vacuuming.
- Fans and aircon are fine; close the outside-air intake on window units.
🛏️ Set up a clean-air room for kids
- Pick one room, usually the bedroom, and keep its door and windows shut.
- Run a portable HEPA air purifier sized for the room: NEA suggests a smoke CADR at least 3× the room volume in m³.
- Air the room out when outdoor air improves to avoid stuffiness and CO₂ build-up.
🧩 Safe indoor play ideas
- Blanket forts, Lego, puzzles and board games.
- Baking, drawing and craft projects.
- Gentle movement: kids' yoga, dance-along videos, balloon games.
- Air-conditioned indoor playgrounds, libraries and museums.
🩺 When to see a doctor
- Breathing difficulty, wheezing or chest tightness.
- Asthma symptoms that need the inhaler more than usual.
- Eye, nose or throat irritation that does not ease after going indoors.
- Any child who seems unwell. MOH advises children who are not feeling well to seek medical advice. In an emergency call 995.
How Haze Buddy decides: PSI and PM2.5 guide for kids
| 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. |
| 🟡 Keep it short | 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. |

Haze FAQ for Singapore parents
Is it safe for kids to play outside in the haze today?
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 keep it short and light, following the official advice for children to minimise prolonged or strenuous outdoor exertion. Red (PSI above 200 or PM2.5 above 150) means stay indoors.
What PSI level is unhealthy for children?
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
Do schools in Singapore change outdoor activities during haze?
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.
What is the difference between PSI and PM2.5?
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.
How does Haze Buddy decide?
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.
Should my child wear an N95 mask in the haze?
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.
