Air quality in Senigallia is shaped mainly by vehicle traffic on the coastal SS16 and summer tourist congestion, against a backdrop of the Marche landscape on the Adriatic coast of the Marche. Ventilation varies with the terrain, and conditions are typically at their best when weather systems move through more actively, while extended dry, calm periods tend to coincide with the town's least favourable air quality readings.

Is air quality bad in Senigallia right now?
On 9 August 2026, overall air quality in Senigallia is medium. AQI is the main air quality indicator at 40.3/100. Pollution peaks around 3:00 PM (O3: 40.3/100).

On 10 August 2026, air quality conditions in Senigallia will be worse than today, with NO2 forecast at fair at 25.1/100. Pollution peaks around 4:00 PM (O3: 44.6/100).
When is air pollution at its worst in Senigallia?
In Senigallia, reduced air quality is most noticeable when pine and oak pollen is at its peak, and on days affected by vehicle traffic on the coastal SS16 and summer tourist congestion; conditions tend to settle down again once weather patterns shift and the local Marche terrain ventilates more freely, usually bringing several weeks of steadier readings.
Are air quality levels in Senigallia based on measurements or forecasts?
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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
