Worst air pollution Omagh, today and tomorrow

On 9 August 2026, overall air quality in Omagh is fair. AQI is the main air quality indicator at 24.2/100. Pollution peaks around 12:00 PM (O3: 24.2/100).

On 10 August 2026, air quality conditions in Omagh will be better than today, with AQI forecast at good at 18.3/100. Pollution peaks around 11:00 PM (O3: 18.3/100).

Omagh doesn't have one fixed air quality level — it swings between two extremes each year. In deep winter, a lack of wind lets M1 traffic fumes and woodsmoke settle instead of blowing through. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter. The shoulder seasons generally bring the mildest readings of the year.

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.
