The Natural Resources and Environment Board's Daily Haze Watch recorded Kuching's Air Pollutant Index (API) at 87 as of 8am Monday, seven points lower than Sunday afternoon.

Serian dropped from 157 to 98, while Samarahan fell from 151 to 92. Lundu and Tebedu also moved down from unhealthy readings to 93 and 73.

API readings from 51 to 100 are classified as moderate, while 0 to 50 is considered good.

These API figures are a time-specific snapshot from 2026-08-17, 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.
