Fort William's position in Highland means air quality is mostly determined by local road traffic and the compact scale of the centre. Cooler northerly winds do most of the work keeping things in check, more so than any local policy or infrastructure change. The M90 sees the heaviest traffic, and that shows up clearly in local roadside monitoring.

When is air pollution at its worst in Fort William?
Here's the thing about Fort William: air quality has a clear seasonal rhythm. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M90 closer to ground level. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Fort William 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.
