Risk Analysis: Four areas in Sarawak and Kuala Lumpur Record Unhealthy Air Quality

Four areas in Sarawak and Kuala Lumpur Record Unhealthy Air Quality

Executive Summary for Unhealthy Air Quality in Sarawak and Kuala Lumpur

Three areas in Sarawak and one in Kuala Lumpur recorded Air Pollutant Index (API) readings in the unhealthy range on 27 August 2026, based on data from the Malaysian Air Pollutant Index Management System (APIMS). Samarahan recorded the highest API in Sarawak at 164, followed by the Serian District Police Headquarters at 162 and Sri Aman at 155, while Cheras in Kuala Lumpur recorded 129. A total of 61 monitoring stations recorded moderate readings and two recorded good readings, with no stations reporting very unhealthy or hazardous levels, though data for Politeknik Kota Kinabalu, Sabah, was unavailable.

  • Date of Event: 27 August 2026
  • Location: Samarahan, Serian and Sri Aman (Sarawak); Cheras (Kuala Lumpur), Malaysia
  • Risk Category: Environment
  • Severity Score:  3/5
  • Confidence Level: 78%

What is Risk Analysis in the Context of Environment Events

Environmental event risk analysis assesses the impact of elevated Air Pollutant Index (API) readings on public health, outdoor activity and essential services. Sustained haze episodes can reduce visibility, aggravate respiratory conditions and prompt precautionary measures such as school closures or the rescheduling of outdoor events in affected areas.

Known Hotspots and Sensitive Areas

High Impact

  • Samarahan, Sarawak (API 164)
  • Serian District Police Headquarters, Sarawak (API 162)
  • Sri Aman, Sarawak (API 155)

Medium Impact

  • Cheras, Kuala Lumpur (API 129)
  • Other monitoring stations recording moderate readings nationwide
  • Areas near ongoing regional haze sources

Low Impact

  • Monitoring stations recording good API readings
  • Areas outside current unhealthy-range monitoring zones

Impact on Transportation and Services

Reduced visibility from the haze may affect road and air travel in the worst-hit areas, while outdoor events and school activities in Sarawak and parts of Kuala Lumpur could face precautionary adjustments. Authorities are monitoring conditions closely ahead of the National Day and Malaysia Day celebrations, with some events already under review because of deteriorating air quality.

Recommended Actions

  • Limit prolonged outdoor exposure in areas with unhealthy API readings.
  • Wear an N95 mask outdoors if sensitive to air pollution.
  • Monitor hourly API updates via the MyJAS EQMS app or eqms.doe.gov.my.
  • Keep windows closed and use air purifiers indoors where possible.

Final Thoughts

The unhealthy API readings recorded in Samarahan, Serian, Sri Aman and Cheras point to a moderate and developing air-quality risk that could worsen if haze conditions persist. Continued monitoring is advised, particularly in Sarawak, where the highest concentrations were recorded.
