Emissions along the A483 represent the town's main traffic-related pollution source. Worthing sits within West Sussex, and its air quality profile is driven mainly by road traffic and the density of the centre. The region's typical south-westerlies tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels.

When is air pollution at its worst in Worthing?
If you're tracking air quality in Worthing, expect it to move around quite a bit through the year. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A483 closer to ground level.
Are air quality levels in Worthing 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.
