Haze conditions have emerged across several regions in Malaysia. Initially, air quality in Perak reached an Air Pollutant Index (API) reading of 153, prompting officials to advise the public to reduce outdoor activities. Authorities noted that while open burning is prohibited, the practice continues during dry weather, and they are monitoring potential transboundary haze.

By mid-August, air quality reached unhealthy levels in Cheras, with the API hitting 151. The Department of Environment has increased patrols to prevent open burning in high-risk areas such as industrial zones and illegal landfills. Officials have emphasized that under the Environmental Quality Act 1974, offenders face significant fines and potential imprisonment.
