Runny nose, itchy eyes, fatigue… people allergic to pollens begin to suffer with the arrival of fine weather and the flowering of certain early species. This is the case with alder, birch, ash and cypress pollen which can start as early as February. But, in general, it is in March that the worries really begin. From April and May, plane and cypress trees as well as birch, willow, beech and hornbeam begin to bud. This is tree season.

Thereafter, from May to August, begins that of the grasses. These are cereal-type plants, such as wheat, barley, corn, rye, oats. With birch pollen, they are most often responsible for the most important allergic manifestations. There remains the herbaceous season, including nettles and other roadside weeds, which runs from May to the end of September. Finally, we must not forget the ambrosia, which rages in August and September.

Until when should I be wary? Pollens are present in the air until the beginning of autumn, that is to say in the month of September. But depending on the region of France, climatic conditions oblige, the species do not always produce pollen at the same time. In order to identify the risks near your place of residence, it is best to consult the site of the National Aerobiological Surveillance Network.
