France Faces Intensified Pollen Crisis with Over Two-Thirds of Country Affected
High birch pollen levels, driven by climate change and warm weather, prompt health precautions as Atmo France's new monitoring index highlights widespread exposure.
- More than two-thirds of France is experiencing high pollen levels, with some regions, including the Ardennes and Charleville-Mézières, under 'extremely high' alerts.
- Atmo France has implemented a six-level pollen index after assuming monitoring responsibilities from the now-defunct RNSA in March 2025.
- The current pollen surge primarily affects northern, eastern, and central regions, including Brittany, Normandy, Île-de-France, and the Grand-Est.
- Health authorities recommend measures such as avoiding outdoor activities during peak pollen times, rinsing hair, and not drying clothes outside to reduce exposure.
- Climate change is contributing to longer and more intense pollen seasons, with approximately 30% of adults and 20% of children in France affected by pollen allergies.
