France Faces Early and Intense Allergy Season in 2026
Allergy sufferers in France should prepare for an early and potentially severe season. Across much of the country, the allergic risk is currently rated as “high,” according to the Atmo air quality observatory, with the north of Alsace already on maximum alert. The only regions currently experiencing some respite are the Southwest, Corsica and the Provence-Alpes-Côte d’Azur (PACA) region.
What’s Driving the Early Start?
This early onset of allergy symptoms is linked to an unusually mild late February, triggering early flowering of plants. Without significant rainfall to clear the air, pollen grains remain suspended and are easily spread by the wind [Atmo GrandEst]. The recent passage of Sahara desert dust also contributed, irritating respiratory tracts and exacerbating allergy symptoms.
Which Pollens are Currently High?
Currently, alder pollen is particularly prevalent and aggressive. Though, other pollens, including birch, cypress, hazel, and ash, are also contributing to the high allergy risk. Grass pollens are expected to become more dominant as the season progresses.
A Lengthening Allergy Season
Allergists are observing a concerning trend: the allergy season is expanding. Dr. Sophie Silcret-Grieu, an allergist, noted that some patients are experiencing symptoms from the complete of January through September, leaving them with only three months of relief per year [Atmo France].
What Can Allergy Sufferers Do?
Given the extended and potentially intense season, allergy sufferers are advised to anticipate their treatments and initiate taking preventative measures as early as possible. Consulting with a healthcare professional for personalized advice is recommended.
