In Montargis, agricultural traffic and river-valley industry is the primary local source affecting air quality, near the Indre, while the wide Loire valley allows steady airflow, generally keeping conditions moderate to good on most days. Cold, still winter spells are the main risk for particulate build-up, while summer usually sees cleaner air except during occasional heatwave-driven ozone episodes.

Frequently Asked Questions

Is air quality bad in Montargis right now?

On 23 August 2026, overall air quality in Montargis is fair. AQI is the main air quality indicator at 30.5/100. Pollution peaks around 6:00 PM (O3: 30.5/100).

Will air quality be worse tomorrow in Montargis?

On 24 August 2026, air quality conditions in Montargis will be similar to today, with AQI forecast at fair at 36.1/100. Pollution peaks around 4:00 PM (O3: 36.1/100).

When is air pollution at its worst in Montargis?

In Montargis, the combination of agricultural traffic and river-valley industry and heavy oak and plane pollen in spring is what most affects sensitive groups; the wide Loire valley allows steady airflow, so poor conditions rarely last more than a couple of days.

Are air quality levels in Montargis 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.
