Lubok Antu haze closes 30 schools on Aug 28 as the district’s API reaches 200. The Sarawak Education Department’s temporary closure covers 28 primary schools with 2,242 pupils and two secondary schools with 1,793 students. The API reading was 200 at 8pm on Thursday, after reaching 210 at 4pm. This is a Lubok Antu district order, not a closure of every school in Sarawak. JPN Sarawak told schools to monitor APIMS readings and follow haze-related safety procedures. Parents should check with their school or the district education office for any update because the notice does not give a reopening time. Location: Lubok Antu, Sarawak

Sarawak still had five unhealthy air-quality stations on Thursday, and Lubok Antu’s reading rose from 182 at 8am to 191 by noon. Kuching remained in the moderate band, moving from 97 to 95. The noon table from Sarawak’s Natural Resources and Environment Board (NREB) listed Lubok Antu at 191, Samarahan at 162, IPD Serian at 158, Sri Aman at 156 and Lundu at 142 — all in the unhealthy range. Tebedu and the other listed stations were moderate. The number of unhealthy stations was unchanged from the morning reading, but the individual figures shifted during the day. API readings use a 24-hour running average of the dominant pollutant; 101 to 200 is classed as unhealthy and can worsen conditions for people with heart or lung complications. Anyone planning a long period outdoors should check the latest APIMS reading first. People in high-risk groups should take extra care if the air turns smoky or the API rises further.

Five Sarawak air-quality stations were in the unhealthy range at 8am on Thursday, while Kuching remained moderate. The Natural Resources and Environment Board’s latest reading put Lubok Antu highest at 182, followed by Samarahan at 164, IPD Serian at 162, Sri Aman at 155 and Lundu at 106. Kuching recorded 97. The readings are based on a 24-hour running average, so the situation can shift with rain, wind and smoke movement. Regional monitoring also points to dry conditions and fire activity in parts of Kalimantan, with a continuing risk of haze reaching western Sarawak. An API reading from 101 to 200 is classed as unhealthy, with greater concern for people who have heart or lung conditions. Kuching residents can check the latest APIMS reading before spending long periods outdoors; if the air turns visibly smoky, reduce strenuous activity and keep children and high-risk family members away from prolonged exposure.

Heavy rain brought Kuching’s API down to 156 by 5pm, but five Sarawak areas were still in the unhealthy range. The latest APIMS readings reported on Tuesday put Serian at 182, followed by Sri Aman at 172, Samarahan at 155, Kuching at 156 and Sarikei at 154. The 10am update had placed Serian at 194 and Kuching at 176, so the afternoon rain helped in parts of the state without ending the haze situation. An API reading from 101 to 200 is classified as unhealthy. That means a lower Kuching number after rain should not be read as a return to normal air: conditions can differ sharply between monitoring stations and can change again when wind or rain patterns shift. For residents planning outdoor work, exercise or travel across Sarawak, check the latest station reading on APIMS before heading out instead of relying on how the sky looks in one neighbourhood. People who are more sensitive to haze should reduce strenuous outdoor time while the readings remain above 100. The same update also placed Marudi under MetMalaysia’s Level 1 hot-weather alert, which covers maximum temperatures of 35–37°C for at least three consecutive days. The next useful checkpoint is whether the five unhealthy stations fall below 101 after further rain, or climb again if dry weather returns.

Kuching's Air Pollutant Index (API) reading reached 175 at 8am on Aug 24, putting the city in the unhealthy range. Five Sarawak locations recorded unhealthy readings at 8am: Serian (189), Kuching (175), Samarahan (170), Sri Aman (158) and Bintulu (108). Kuching's reading was 175, down slightly from 177 at 4pm on Sunday. An API reading of 101–200 is classed as unhealthy, while 201–300 is very unhealthy. These are 8am readings, not a live noon update, so check the latest official reading before planning outdoor activities. Kuching South City Council (MBKS) distributed face masks at Kenyalang Market and Sungai Apong Market on Aug 23. Children, senior citizens and people sensitive to poor air quality should cut down unnecessary outdoor activity, wear a suitable mask, stay hydrated and seek medical attention if they have breathing difficulty. For people who must go outdoors, the useful detail is fit: a well-sealed N95, KN95 or KF94 offers better particle protection than a loose face covering. Children, older people and anyone with asthma or heart or lung conditions should keep outdoor exertion down while the reading remains unhealthy.

Kuching pharmacists are urging the public to use well-fitting, high-filtration masks as haze worsens. SHiNE Pharmacy chief pharmacist Christina Wong said N95 and KN95 respirators offer better protection from fine particles than loose-fitting surgical masks. Song Plaza Caring Pharmacy pharmacist Wendy Tsai also recommended KF94 masks, which are available in adult and children’s sizes. Both pharmacists stressed that fit matters. Parents were advised to keep young children indoors when air quality is poor, while older people and those with asthma or chronic lung conditions should take extra care outdoors.

Haze is keeping 591 Sarawak schools closed on Aug 21. The Sarawak Education Department said the temporary closure took effect on Aug 20 and will continue tomorrow, Aug 21, after unhealthy Air Pollutant Index (API) readings were recorded at 3pm. The order affects 509 primary schools with 107,590 pupils and 82 secondary schools with 89,733 students. The 10 affected district education offices cover Kuching, Padawan, Bau, Lundu, Samarahan, Simunjan, Serian, Sri Aman, Lubok Antu and Betong. Schools have been told to monitor readings through the Department of Environment's APIMS system and follow Ministry of Health advice. Any further update will be announced by the department. Because these readings are tied to 2026-08-20, parents should check the latest APIMS update and their school's notice before making plans for attendance or outdoor activities. A reopening is not a permanent all-clear if the API rises again. [image: 1787220315028-haze-chimon-20260820.jpg]

Haze returned to Sarawak on Aug 19, with five monitoring areas recording unhealthy air quality at 9am. Serian recorded the highest Air Pollutant Index (API) reading at 156, followed by Kuching at 154, Sri Aman at 152, Samarahan at 113 and Mukah at 106. The figures were a snapshot from the Department of Environment's APIMS system, not a forecast for the whole day. in Kuching An API reading from 101 to 200 is classified as unhealthy. The number can move as wind, rain and nearby hotspots change, so an old screenshot should not be used as the current reading. Check APIMS again before school sports, outdoor work or a long trip. Children, older people and anyone with asthma or heart or lung conditions should be more cautious when readings are elevated. Reducing strenuous outdoor activity, closing windows when smoke is strong and using a well-fitting high-filtration mask outdoors are more useful than relying on a loose cloth mask.
