Istanbul currently ranks #40 of 50 tracked cities for PM2.5 (1 = most polluted). Its PM2.5 level of 11.3 µg/m³ is within the WHO 24-hour guideline of 15 µg/m³. A US AQI of 51 falls in the “Moderate” 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.
