Like much of Gloucestershire, Tewkesbury's air quality is shaped less by industry these days and more by everyday road traffic. The nearby M25 corridor contributes steady vehicle emissions that affect roadside readings. Thanks to southwesterly winds, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards.

When is air pollution at its worst in Tewkesbury?
If you're tracking air quality in Tewkesbury, expect it to move around quite a bit through the year. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. In deep winter, a lack of wind lets M25 traffic fumes and woodsmoke settle instead of blowing through. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in Tewkesbury 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.
