Nowy Sącz' air quality faces significant winter challenges in the Dunajec and Kamienica river valley enclosed by the Beskid Sądecki and Beskid Wyspowy mountain ranges, with residential coal and wood burning generating elevated PM2.5 under frequent winter inversions. Vehicle traffic on the S10 expressway contributes locally, while the deep Carpathian valley topography creates severe topographic concentration that makes Nowy Sącz one of southern Poland's more persistently challenging winter air quality environments.

Frequently Asked Questions
Is air quality bad in Nowy Sącz right now?
On 20 September 2026, overall air quality in Nowy Sącz is fair. AQI is the main air quality indicator at 25.1/100. Pollution peaks around 7:00 PM (NO2: 25.1/100).
Will air quality be worse tomorrow in Nowy Sącz?
On 21 September 2026, air quality conditions in Nowy Sącz will be similar to today, with AQI forecast at fair at 26.8/100. Pollution peaks around 6:00 PM (NO2: 26.8/100).
When is air pollution at its worst in Nowy Sącz?
Nowy Sącz residents notice reduced air quality mainly when oak and beech pollen peaks, and during spells of residential coal and wood burning; wind and rain both help clear the air fairly quickly here. Sensitive residents may notice the difference most on still, humid days when emissions linger close to ground level.
Are air quality levels in Nowy Sącz 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.
