Air quality across Penang has reached unhealthy levels, with all four monitoring stations reporting concerning readings as of Monday morning. The Minden station recorded the highest API reading of 167, indicating unhealthy air conditions that pose risks to public health, particularly for vulnerable groups including children, the elderly, and those with respiratory conditions.

The simultaneous unhealthy readings across multiple monitoring zones suggest a statewide air quality issue affecting residents throughout the state. An API reading in the 101-200 range is classified as unhealthy, signifying that members of the general public may experience health effects with prolonged or strenuous outdoor activities.

Malaysians in Penang are advised to monitor air quality updates regularly and take appropriate precautions, including limiting outdoor activities and using air purifiers indoors. The Department of Environment will continue to track air quality developments and provide updates to the public as conditions change.
