Tenby's position in Pembrokeshire means air quality is mostly determined by local road traffic and the compact scale of the centre. Northwesterly winds off the coast help ventilate the town centre, keeping air quality at moderate levels typical for the region. Commuter traffic feeding onto the A55 adds a further, consistent contribution to local readings.

When is air pollution at its worst in Tenby?
You can roughly predict Tenby's air quality just by knowing the time of year. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Winter mornings can be the trickiest, with cold, still conditions trapping A55 traffic fumes and smoke from home fires close to the ground. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Tenby 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.
