Check on the official DOE websiteWhat the API level means
DOE reports air quality as the Air Pollutant Index. The higher the number, the worse the air. During haze, fine particles (PM2.5 and PM10) usually set the reading.
| API | Health effect | What to do |
|---|---|---|
| 0–50 Good | Low pollution. No ill effects. | Normal activities. |
| 51–100 Moderate | Few or no ill effects for most people. | People with asthma or heart disease watch for symptoms. |
| 101–200 Unhealthy | Symptoms worsen in people with heart and lung disease. Irritation in healthy people. | Cut outdoor exercise. Sensitive groups stay indoors. N95 outdoors. |
| 201–300 Very unhealthy | Symptoms spread to healthy people. Less tolerance for exercise. | Avoid outdoor activity. Everyone outdoors wears an N95. |
| 301 and above Hazardous | Healthy people affected. Above 400, may be life-threatening for the ill and elderly. | Stay indoors. Follow government instructions. |

Schools during the October 2026 haze
All schools and educational institutions in Johor were closed from 12 to 16 October 2026 on the decree of the Regent of Johor, as the haze worsened. Closures can be extended or lifted at short notice, so check the latest announcement from the Johor State Education Department (JPN Johor) before sending children to school.
How to protect yourself and your family
- Wear an N95, not a surgical mask. Haze particles are very fine. A well-fitted N95 filters about 95% of them.
- Keep windows and doors closed. An air purifier with a HEPA filter helps in the room you use most.
- Cut outdoor exercise once the API passes 100, and avoid it above 200.
- Drink plenty of water.
- Watch the people most at risk: young children, the elderly, pregnant women and anyone with asthma, heart or lung disease.
- See a doctor for breathing difficulty, chest pain or symptoms that don’t ease indoors.
For employers: what DOSH expects during haze
The Department of Occupational Safety and Health (DOSH) published a second edition of its workplace haze guideline in October 2026. Employers must assess the risk once the API passes 100 and decide when outdoor work stops. Above 100, strenuous outdoor work should be minimised. Above 200, it should be avoided, susceptible staff move indoors and everyone working outdoors needs a fitted respirator. Above 300, crane lifts and driving need a visibility check.

Haze in Johor: common questions
What is the API in Johor Bahru today?
The live card at the top of this page shows the latest reading from DOE’s Larkin station, which is the main reading for Johor Bahru city, and from the other 7 Johor stations. Pasir Gudang station is the better guide for eastern JB, Masai and Permas Jaya.
Where do these numbers come from?
From the Department of Environment Malaysia (DOE) through its Air Pollutant Index Management System (APIMS). DOE updates the readings every hour. This page refreshes every 15 minutes and always shows the time of the reading.
Is it safe to go outside when the API is above 100?
Between 101 and 200 the air is unhealthy. Most healthy adults can go out briefly, but should cut down outdoor exercise. Children, the elderly, pregnant women and people with heart or lung illness should stay indoors. Above 200, everyone should avoid outdoor activity and wear an N95 mask outside.
Do surgical masks protect against haze?
Not well. Haze is mostly very fine particles. A properly fitted N95 respirator filters about 95% of them. Surgical and cloth masks leave gaps at the sides and filter far less.
Do workers have to stop working outdoors during haze?
DOSH’s 2026 haze guideline sets out what employers must do at each API level. Strenuous outdoor work should be minimised above 100 and avoided above 200, susceptible staff move indoors above 200, and above 400 outdoor work should be avoided. Our employer guide explains each step.
