Worst air pollution Znojmo, today and tomorrow

On 9 August 2026, overall air quality in Znojmo is fair. NO2 is the main pollutant at 21.9/100. Pollution peaks around 5:00 PM (O3: 49.0/100).

On 10 August 2026, air quality conditions in Znojmo will be better than today, with AQI forecast at medium at 52.8/100. Pollution peaks around 12:00 PM (O3: 52.8/100).

The clearest dips in Znojmo's air quality track birch and beech pollen peaks and periods of vehicle traffic and vineyard agriculture on the hills; the rest of the year typically brings clearer, more consistent conditions for the South Moravian Region area, particularly once autumn winds set in and the local terrain ventilates more easily than during calmer stretches.

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.
