IPD Serian in Sarawak posted an Air Pollutant Index (API) reading of 188, the highest nationwide and just shy of the 201 mark that would tip it into the “very unhealthy” category.

The mildest readings among the unhealthy group came from the northern states. Balik Pulau in Penang stood at 131 and Minden at 111, while Sungai Petani in Kedah recorded the lowest unhealthy reading nationwide at 103.
Under the DOE’s API classification, readings between 101 and 200 fall within the “unhealthy” category.
