The National Environment Agency reported that 24-hour Pollutant Standards Index readings stood between 65 and 81 on Tuesday morning, with the highest levels registered in the western region. Forecasts indicate that air quality will stay moderate, supported by showers over Singapore, Sumatra, and Kalimantan. While current conditions are safe for normal activities, individuals should still track one-hour PM2.5 concentrations before undertaking strenuous exercise. Vulnerable segments of the population, such as children and the elderly, must avoid heavy physical exertion if readings rise into elevated bands.
