Worst air pollution Milan, today and tomorrow

On 18 July 2026, overall air quality in Milan is poor. AQI is the main air quality indicator at 65.7/100. Pollution peaks around 1:00 PM (O3: 65.7/100).

On 19 July 2026, air quality conditions in Milan will be similar to today, with AQI forecast at poor at 61.0/100. Pollution peaks around 1:00 PM (O3: 61.0/100).

Air quality dips in Milan mostly track canal corridor plane and birch pollen peaks and periods of this produces some of the EU's highest NO₂ and PM2.5 concentrations, while summer Po; the rest of the calendar year is generally more forgiving for air quality.

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
