On 30 August 2026, overall air quality in Asti is moderate. AQI is the main air quality indicator at 59.4/100. Pollution peaks around 5:00 PM (O3: 59.4/100).

On 31 August 2026, air quality conditions in Asti will be similar to today, with AQI forecast at moderate at 56.4/100. Pollution peaks around 1:00 PM (O3: 56.4/100).

You're quickest to notice worse air in Asti when local tree and grass pollen peaks, or due to vehicle traffic on the A21 motorway and neighbouring wine and agri-food industry; things typically settle down again once the weather pattern shifts.

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.
