Residents planning a long stretch outdoors should check the newest reading rather than rely on the 2pm figure. Children, older people, pregnant women and people with heart or respiratory conditions face higher risk. Anyone who develops breathing difficulty should seek medical care.

Lubok Antu posted the 2pm watch's most severe reading at 469, rated Very Hazardous. IPD Serian was at 370 and Lundu at 305, both Hazardous; Samarahan recorded 271 and Sri Aman 282, joining Kuching in the Very Unhealthy range. Miri's 100 was Moderate. The API is a 24-hour running average based on the dominant pollutant, not a single moment outdoors: 201 to 300 is Very Unhealthy, 301 to 400 Hazardous and 401 to 500 Very Hazardous.
