Traffic on the A47 is the most significant local emissions source, especially at peak times. Being part of Cheshire East, Wilmslow sees an air quality profile that's largely down to traffic and general town-centre activity. Cooler northerly winds offer a degree of natural ventilation, keeping pollution broadly in line with comparable UK towns.

When is air pollution at its worst in Wilmslow?
If you're tracking air quality in Wilmslow, expect it to move around quite a bit through the year. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A47 traffic emissions linger rather than disperse. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Wilmslow 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.
