BATU PAHAT, 11 OCTOBER 2026 —
Haze pushed air pollution to unhealthy levels in 33 locations across Malaysia as of 6 a.m. on Monday, with Batu Pahat in Johor posting the highest Air Pollutant Index (API) reading of 189, the Malaysian Air Pollutant Index Management System (APIMS) said.
Market Impact
The API readings between 101 and 200 are classified as unhealthy, prompting health advisories for children, the elderly and people with respiratory conditions to limit outdoor activities and wear face masks if they must venture out. Thirty‑five monitoring stations recorded moderate air quality, with API values ranging from 54 to 99, while no station registered very unhealthy or hazardous levels at that time.
Johor was the most affected state, registering eight locations with unhealthy readings. Batu Pahat led with 189, followed by Pasir Gudang and Tangkak at 186 each, Larkin at 185, Segamat at 183, Kluang at 177, Kota Tinggi at 174 and Pengerang at 169. The Klang Valley and surrounding districts also faced unhealthy air, with Cheras at 175, Batu Muda and Johan Setia each at 171, Shah Alam at 170 and Putrajaya at 169.
Petaling Jaya and Klang posted 162, Banting 159 and Kuala Selangor 154.
In Negeri Sembilan, Seremban recorded an API of 186, Nilai 180 and Port Dickson 166. Melaka’s Bukit Rambai, Bandaraya Melaka and Alor Gajah posted 178, 175 and 174 respectively. Perak’s Tasek Ipoh measured 176, Pegoh Ipoh 172, Tanjung Malim 169 and Seri Manjung 156. Pahang’s Rompin registered 167, while Temerloh and Indera Mahkota in Kuantan each logged 152.
Outside the peninsula, Kuching in Sarawak recorded an unhealthy reading of 151. In Penang, Seberang Perai measured 137, and Sungai Petani in Kedah posted 119.
The widespread unhealthy API levels underscore the regional impact of the haze, which has prompted public health warnings and could affect daily activities and productivity. The APIMS data will continue to be updated as conditions evolve, providing authorities and the public with real‑time information on air quality across the country.
