Unhealthy Air Quality in Sarawak Raises Public Health Concerns

KUALA LUMPUR, AUGUST 2026 – Worsening haze conditions across parts of Sarawak have raised public health concerns after Serian, Kuching and Samarahan recorded unhealthy Air Pollutant Index (API) readings.

As of noon, Serian recorded the highest API reading in the state at 162, followed by Samarahan at 140 and Kuching at 139. All three readings fall within the unhealthy category.

Under Malaysia’s API classification, readings between 101 and 200 are considered unhealthy and may begin to affect the health of the general population, particularly those who are more sensitive to air pollution.

Children, senior citizens, pregnant women and individuals with asthma, chronic lung disease or heart conditions are among the groups most vulnerable to worsening air quality.

Health authorities have advised people in affected areas to reduce prolonged or strenuous outdoor activities, especially when haze conditions are visibly severe.

Those who need to be outdoors are encouraged to use appropriate face masks, stay well hydrated and monitor their health closely for symptoms such as coughing, breathing difficulties, chest discomfort, eye irritation or headaches.

People with existing respiratory conditions are also advised to keep prescribed medication nearby and seek medical attention if symptoms worsen.

The Department of Environment continues to monitor air quality through the Air Pollutant Index Management System as haze remains present across several parts of Sarawak.

While Serian, Kuching and Samarahan entered the unhealthy range, other monitoring stations in the state remained within the moderate category, with API readings reported between 57 and 91.

Moderate air quality is generally acceptable for most people, although individuals who are especially sensitive to pollution may still experience discomfort after prolonged exposure.

The haze has also reduced visibility in several areas, with parts of Kuching and surrounding districts covered by a noticeable layer of smoke.

Reduced air quality can increase the risk of respiratory irritation and may worsen existing conditions such as asthma, bronchitis and other lung-related illnesses.

The situation is believed to be linked partly to transboundary haze originating from forest and land fires in West Kalimantan, Indonesia.

Prevailing winds during the dry season can carry smoke across the border into western Sarawak, affecting districts including Kuching, Samarahan and Serian.
