7-Day Pollen Forecast for Lyon
Pollen Season in Lyon
Lyon sits where the Saône meets the Rhône, in a corridor between the Monts d'Or and the Alpine foothills that funnels north–south winds and traps warm, still air in summer. The season opens in late winter with cypress and other Cupressaceae, followed by ash and poplar, then birch through April and plane in mid-spring — plane is unavoidable given the rows lining the Rhône quays, Cours Gambetta and the alleys of Parc de la Tête d'Or. Oak and grasses take over from May, with grass peaking through June on the open lawns of Tête d'Or, Parc de Gerland, Parc de Parilly and the riverside Parc de la Feyssine. What sets Lyon apart is ragweed: the Rhône valley is the most heavily colonised part of France, and ambrosia pollen from August into late September affects many people who have no trouble in spring. It thrives on riverbanks, roadsides, building sites and fallow ground in the plain around the city, and winds along the valley carry it into every arrondissement.
- Treat late August and September as a second season here — ragweed counts in the Rhône valley can be higher than spring tree pollen, so check the daily bulletin before planning outdoor time.
- Keep away from disturbed ground, towpaths along the Rhône and Saône and construction edges in late summer, where ragweed colonises fastest.
- During the June grass peak, avoid the big lawns at Tête d'Or, Gerland and Parilly on mowing days and in the warm late afternoon, and speak to a pharmacist early rather than waiting for symptoms to build.
