The Air Pollutant Index Management System recorded Sri Aman at 229 and Serian at 228 on Aug 29. Kuching was at 180, Sarikei 194 and Samarahan 185, putting those stations in the unhealthy range alongside Mukah, Sibu, Bintulu, Kapit and Samalaju.

Only ILP Miri, Miri and Limbang remained in the moderate range, at 77, 76 and 56 respectively. All listed areas rose from the 10am readings, making this a materially worse afternoon snapshot rather than a repeat of the morning update.

Under the API scale, 201–300 is very unhealthy and 101–200 is unhealthy. Residents can check the latest APIMS reading before prolonged outdoor activity, as the numbers may change with wind and rain.
