BMKG reported PM2.5 concentrations at the Musi 2 station hitting 903.6 µg/m³ on October 4, 2026, placing the area in the highest warning category.

In Jakarta, the air quality was ranked as the third worst globally on Monday morning, with an AQI of 172. Weather forecasts for the capital indicate mostly cloudy conditions with potential light rain in South and East Jakarta.
