Worst air pollution Naples, today and tomorrow

On 18 July 2026, overall air quality in Naples is fair. PM2.5 is the main pollutant at 29.0/100. Pollution peaks around 2:00 PM (O3: 46.7/100).

On 19 July 2026, air quality conditions in Naples will be similar to today, with NO2 forecast at fair at 22.0/100. Pollution peaks around 1:00 PM (O3: 40.5/100).

Air quality dips in Naples mostly track local combined tree and grass pollen peaks and periods of high traffic density, scooter emissions, and the Bagnoli industrial legacy site contribute sustained local; conditions usually ease once the wet season or windier weather returns.

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.
