St Andrews's position in Fife means air quality is mostly determined by local road traffic and the compact scale of the centre. The A96 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours. Cooler northerly winds help ventilate the town centre, keeping air quality at moderate levels typical for the region.

When is air pollution at its worst in St Andrews?
St Andrews doesn't have one fixed air quality level — it swings between two extremes each year. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter. Winter mornings can be the trickiest, with cold, still conditions trapping A96 traffic fumes and smoke from home fires close to the ground. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in St Andrews 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.
