Being part of Windsor and Maidenhead, Windsor sees an air quality profile that's largely down to traffic and general town-centre activity. Shifting coastal winds usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns. Commuter traffic feeding onto the A82 adds a further, consistent contribution to local readings.

When is air pollution at its worst in Windsor?
Spring and autumn are typically the easiest months, air-quality-wise, for most residents. In Windsor, pollution levels don't stay flat — winter and summer look pretty different. In deep winter, a lack of wind lets A82 traffic fumes and woodsmoke settle instead of blowing through. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days.
Are air quality levels in Windsor 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.
