Kielce's air quality reflects its position in the Świętokrzyskie Mountains highlands of central Poland, with residential coal and wood burning generating elevated PM2.5 alongside vehicle traffic on the S7 expressway. The surrounding Świętokrzyskie ridgelines create more complex topographic ventilation than the flat Polish plain, while the region's limestone quarrying and cement manufacturing industry contributes elevated PM10, and Kielce's coal heating dependency creates the seasonal PM2.5 challenge typical of Polish cities during the winter heating season.

Frequently Asked Questions
Is air quality bad in Kielce right now?
On 30 August 2026, overall air quality in Kielce is moderate. AQI is the main air quality indicator at 54.8/100. Pollution peaks around 6:00 AM (NO2: 54.8/100).
Will air quality be worse tomorrow in Kielce?

When is air pollution at its worst in Kielce?
Residents in Kielce are quickest to notice reduced air quality when oak and pine pollen peaks, or due to residential coal and wood burning; the picture usually improves again once the season turns. Local monitoring stations typically pick up the clearest signal during these peak periods.
Are air quality levels in Kielce 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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
