Commuter traffic feeding onto the M27 adds a further, consistent contribution to local readings. Bognor Regis sits within West Sussex, and its air quality profile is driven mainly by road traffic and the density of the centre. Northwesterly winds off the coast usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

When is air pollution at its worst in Bognor Regis?
Spring and autumn are typically the easiest months, air-quality-wise, for most residents. You can roughly predict Bognor Regis's air quality just by knowing the time of year. Through the colder months, readings near the M27 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days.
Are air quality levels in Bognor Regis 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.
