Rush-hour queues near the A14 are usually when readings climb the most. Rochester sits within Medway, and its air quality profile is driven mainly by road traffic and the density of the centre. Moist Atlantic fronts offer a degree of natural ventilation, keeping pollution broadly in line with comparable UK towns.

When is air pollution at its worst in Rochester?
Ask a local in Rochester and they'll tell you air quality changes noticeably from season to season. 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 A14 traffic emissions linger rather than disperse. Spring and autumn tend to be the calmer, more moderate stretches by comparison.
Are air quality levels in Rochester 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.
