What this means
Mumbai currently ranks #9 of 50 tracked cities for PM2.5 (1 = most polluted). Its PM2.5 level of 75 µg/m³ is 5× the WHO 24-hour guideline of 15 µg/m³. A US AQI of 154 falls in the “Unhealthy” band; see the health guide for what each band means.
Figures are hourly values from the Open-Meteo Air Quality API, modelled from Copernicus CAMS forecasts for the city-centre coordinates rather than read from a single ground station. Concentrations are in micrograms per cubic metre; the US AQI follows EPA breakpoints and reports the worst pollutant. Data is cached for 15 minutes.
