PETALING JAYA, MALAYSIA, 6 OCTOBER 2026 —
Air quality in parts of Negri Sembilan and Johor deteriorated into unhealthy levels yesterday, with the Air Pollutant Index (API) reaching between 111 and 156, according to data from the Malaysian Meteorological Department (MetMalaysia).
Market Impact
Five areas in Johor—Batu Pahat, Kluang, Segamat, Larkin and Tangkak—recorded unhealthy API readings, while Nilai and Seremban in Negri Sembilan hit 146 and 139, respectively. Samarahan in Sarawak was the only Borneo area with an unhealthy reading of 119, though it was 25% higher earlier in the day.
The spike in pollution has triggered respiratory issues, with the Johor Doctors Association reporting a 20% increase in cases. Dr. Mohamed Amin Kader, president of the association, warned that the haze, combined with influenza outbreaks, was worsening symptoms such as coughing and advised prompt medical attention for affected individuals.
Parents in affected areas have restricted outdoor activities, with some keeping children indoors. Amir Abdullah, a building executive in Johor Baru, said his eight-year-old son—sensitive to dust—has suffered from nasal congestion since the haze began. "I make my sons wear masks when they go to school and kindergarten, even though they complain," he said.
Taxi driver Tan Wei Ming, 58, noted worsening haze despite recent rain, while housewife Priya, 38, said her family had adjusted routines, avoiding outdoor meals and keeping windows shut due to the smell. Two of her children had recently recovered from severe coughs and flu.
MetMalaysia classifies API readings of 101–200 as unhealthy, with 51–100 considered moderate and 0–50 good. Only three areas—Sandakan (Sabah), Langkawi (Kedah) and Kangar (Perlis)—recorded good air quality, while 54 of the 65 monitored stations nationwide showed moderate levels.
The haze has disrupted daily life, with residents prioritizing indoor safety amid rising health concerns. Authorities and medical professionals are urging caution, particularly for vulnerable groups.
