Worst air pollution Ullapool, today and tomorrow

On 9 August 2026, overall air quality in Ullapool is good. AQI is the main air quality indicator at 18.3/100. Pollution peaks around 1:00 AM (O3: 18.3/100).

On 10 August 2026, air quality conditions in Ullapool will be worse than today, with AQI forecast at fair at 20.0/100. Pollution peaks around 11:00 AM (O3: 20.0/100).

Spring and autumn tend to be the calmer, more moderate stretches by comparison. Seasons make a real difference to air quality in Ullapool, more than most people realise. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A82 traffic emissions linger rather than disperse. 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.

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.

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
