Kuching’s air quality improved to the moderate range by Sunday evening, but Serian and Samarahan were still unhealthy. At 5pm on Aug 16, Kuching’s Air Pollutant Index (API) reading fell to 91. Serian recorded 157 and Samarahan 147, both still in the unhealthy range. API readings from 101 to 200 are classified as unhealthy, while 51 to 100 is moderate. Rain brought some relief after a week of dry weather. All 107 schools under the Serian District Education Office were scheduled to reopen on Aug 17 after temporarily closing when the API went above 200. These API figures are a time-specific snapshot from 2026-08-16, not a full-day forecast. Rain, wind and new hotspots can change the number quickly, so check APIMS again before school sports, outdoor work or a long trip. Children, older people and people with asthma or heart or lung conditions should reduce strenuous outdoor activity while the air remains unhealthy.
