| 0–50 | Good | No restriction on outdoor activities. |
| 51–100 | Moderate | No restriction on outdoor activities. |
| 101–200 | Unhealthy | High-risk groups (the elderly, pregnant women, children, heart and lung patients) should limit outdoor activity. |
| 201–300 | Very Unhealthy | The elderly and high-risk groups should stay indoors and reduce physical activity; people with health problems should see a doctor. |
| > 300 | Hazardous | The elderly and high-risk groups must not go outdoors; the public should avoid outdoor activities. |

Haze and schools
According to a Ministry of Education statement on 8 Oct 2026, its institutions close in areas where the API reading is above 180, or above 150 for three days in a row, and lessons continue at home. Whether a school operates is decided every day by the District Education Office, based on Department of Environment API data.
Check API readings yourself
Hourly API readings for 68 stations are published by the Department of Environment on the APIMS portal (eqms.doe.gov.my). We do not copy those readings because there is no permitted public data channel; open the official portal for the current reading in your area.
