Grass pollen levels are gradually falling, but high levels are still possible in some areas!

In the current late phase of grass pollen release, it is becoming increasingly important for people with grass pollen allergies to pay attention to local conditions. In urban areas, grass pollen levels are now only moderately high, though this can still trigger allergic symptoms in the late morning. Specific locations play a significant role in determining the level of grass pollen in the air. In particular, woodland grasses and grass species growing along rivers and streams are only now beginning to release pollen. In alpine pastures in mountainous areas, too, grass pollen levels can still cause severe symptoms. 

Overall, the concentration of grass pollen in the air is already declining. The rain showers forecast for early July will also bring some relief.

In addition to grass pollen, the pollen spectrum also includes pollen from stinging nettles, sweet chestnuts, silver lime, and species of sorrel and plantain. These types of pollen may be responsible for mild allergic symptoms in certain localised areas.

Stinging nettle pollen, in particular, is set to increase significantly in intensity over the coming weeks. Although stinging nettle pollen does not play a major role as an allergen, it can certainly cause allergic symptoms.

This year, lime trees and sweet chestnut trees are flowering more profusely than average. As a result, unusually high quantities of pollen from these two trees are being released.

In the mountains, the flowering of the green alder has passed its peak. Its pollen is now only likely to cause allergic symptoms locally in people who are sensitive to birch pollen.
