The grass pollen season has now come to an end. A few grains may still be detected sporadically, mainly due to resuspension by the wind, but the active emission period is over. Pollen concentrations remain well below the allergic threshold of 50 grains/m³, and this trend is expected to continue. People allergic to grass pollen should therefore experience lasting relief from their symptoms.

However, in the coming days to weeks, mugwort (Artemisia) pollen will begin to appear in the air. These pollen grains are also allergenic and can trigger reactions in sensitised individuals, who should remain vigilant.

In addition, summer weather conditions are favourable to the development of certain allergenic moulds. Spore concentrations of the Cladosporium and Alternaria genera are currently very high. These spores are among the most common outdoor allergens in summer and can cause respiratory symptoms in sensitive individuals.
