Worst air pollution Evesham, today and tomorrow

On 9 August 2026, overall air quality in Evesham is fair. PM1 is the main pollutant at 29.1/100. Pollution peaks around 4:00 PM (O3: 57.0/100).

On 10 August 2026, air quality conditions in Evesham will be similar to today, with AQI forecast at fair at 24.6/100. Pollution peaks around 5:00 PM (O3: 24.6/100).

Seasons make a real difference to air quality in Evesham, more than most people realise. Once the heating goes on and the air turns still, pollution from the M90 and nearby chimneys tends to build up rather than clear. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily. For much of spring and autumn, things settle into a fairly unremarkable middle ground.

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.
