Worst air pollution Wetherby, today and tomorrow

On 9 August 2026, overall air quality in Wetherby is fair. O3 is the main pollutant at 31.1/100. Pollution peaks around 6:00 AM (NO2: 46.2/100).

On 10 August 2026, air quality conditions in Wetherby will be better than today, with AQI forecast at good at 19.0/100. Pollution peaks around 2:00 PM (O3: 19.0/100).

Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes. In Wetherby, pollution levels don't stay flat — winter and summer look pretty different. Winter mornings can be the trickiest, with cold, still conditions trapping A303 traffic fumes and smoke from home fires close to the ground. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter.

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.
