Worst air pollution Bournemouth, today and tomorrow

On 9 August 2026, overall air quality in Bournemouth is fair. O3 is the main pollutant at 28.4/100. Pollution peaks around 8:00 PM (NO2: 50.4/100).

On 10 August 2026, air quality conditions in Bournemouth will be similar to today, with O3 forecast at fair at 25.0/100. Pollution peaks around 9:00 PM (NO2: 47.8/100).

Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes. You can roughly predict Bournemouth's air quality just by knowing the time of year. Winter mornings can be the trickiest, with cold, still conditions trapping A34 traffic fumes and smoke from home fires close to the ground. 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.

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.
