Worst air pollution Ebbw Vale, today and tomorrow

On 20 September 2026, overall air quality in Ebbw Vale is moderate. AQI is the main air quality indicator at 44.7/100. Pollution peaks around 10:00 PM (PM1: 44.7/100).

On 21 September 2026, air quality conditions in Ebbw Vale will be worse than today, with AQI forecast at poor at 67.4/100. Pollution peaks around 8:00 PM (NO2: 67.4/100).

Seasons make a real difference to air quality in Ebbw Vale, more than most people realise. In deep winter, a lack of wind lets A55 traffic fumes and woodsmoke settle instead of blowing through. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days. The shoulder seasons generally bring the mildest readings of the year.

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.
