Pollution in Lyon: Air quality deteriorates this Tuesday, June 10

Air quality is expected to deteriorate significantly this Tuesday, June 10, 2025, throughout the Lyon metropolitan area.
While Tuesday, June 10th, will be largely sunny across the Lyon region, air quality will deteriorate throughout the day. Thus, Atmo indexes will be degraded across the entire Lyon metropolitan area and even poor in some districts, such as the 4th and 9th arrondissements.
Ozone and multi-pollutant concentrations will be classified as poor by Atmo, the air quality observatory in Auvergne-Rhône-Alpes, and average for nitrogen dioxide and fine particles.
