Pollution in Lyon: Air quality generally good this Thursday

Air quality in Lyon and the greater Lyon area is expected to be generally good this Thursday, June 5, 2025.

After a day of heavy rain in the Lyon metropolitan area, air quality will be good this Thursday, June 5. While conditions are expected to be much less disrupted than the day before, " the remaining cloud cover should help limit ozone production, " notes Atmo, the air quality observatory in Auvergne-Rhône-Alpes.

While the concentrations of nitrogen dioxide, ozone and multi-pollutants will be average, they will be good for fine particles and sulfur dioxide, across the entire Lyon metropolitan area.
