Air quality in York is shaped by its location in York, where vehicle traffic and everyday urban activity dominate local sources. Onshore breezes offer a degree of natural ventilation, keeping pollution broadly in line with comparable UK towns. Commuter traffic feeding onto the A40 adds a further, consistent contribution to local readings.

When is air pollution at its worst in York?
York's air quality follows a familiar seasonal pattern most UK towns share. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A40 traffic emissions linger rather than disperse. 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. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in York based on measurements or forecasts?
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.
