Worst air pollution Thame, today and tomorrow

On 30 August 2026, overall air quality in Thame is fair. AQI is the main air quality indicator at 23.2/100. Pollution peaks around 4:00 PM (O3: 23.2/100).

On 31 August 2026, air quality conditions in Thame will be similar to today, with AQI forecast at fair at 21.1/100. Pollution peaks around 11:00 PM (NO2: 21.1/100).

Thame doesn't have one fixed air quality level — it swings between two extremes each year. Through the colder months, readings near the M40 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter. 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.
