Singapore Air Quality Improves to Moderate Levels After Unhealthy Start

On Saturday, air quality readings in three regions of Singapore began in the unhealthy range. Throughout the day, monitoring data showed a gradual improvement, bringing the index into the moderate category. The shift indicates a reduction in pollutant concentrations across the city-state, suggesting that short‑term measures or natural dispersion may have contributed to the better air quality observed later in the day.
