Peak of the birch pollen season - high allergen load in Tyrol!

In the past week, pollen production and distribution in Tyrol have remained at a high level. We are now in the main phase of the pollen season, in which several tree species bloom at the same time.

Birch pollen: The birch pollen season has now reached its peak. Birch is currently the dominant allergenic pollen type, with high to locally very high allergenic loads throughout the region. This year, the birch pollen season is particularly intense and many allergy sufferers are experiencing severe symptoms. Only periods of precipitation can temporarily reduce the pollen concentrations. Even hornbeam and hop hornbeam are currently in bloom and can reach moderate pollen concentrations. Due to cross-reactions with birch pollen, these species can trigger or intensify allergic reactions, especially in urban areas and parks. Also oak pollen are also present and increasing; although they are generally less allergenic, they can also contribute to symptoms due to cross-reactions with birch pollen.

Ash pollen: Ash pollen are still present in the air and contribute to the allergenic load. Moderate concentrations are predominantly measured in the region.

Sycamore pollen: The concentration of plane tree pollen is expected to increase in the coming week, especially in areas with plane tree populations such as urban avenues.

Other pollen types: Pollen from the cypress family cypress family (Cupressaceae) are still present in the air, but have a low allergenic relevance in Tyrol.

Situation at higher altitudes: The allergenic load at higher altitudes is still lower than in the valleys. However, as the vegetation develops, the pollen concentrations gradually increase there too.

High to very high birch pollen concentrations are currently being observed in large parts of the region, making this phase a particularly challenging time for allergy sufferers. The pollen count is expected to remain high in the coming days. Cooler temperatures and periods of precipitation may provide localised and temporary relief, but overall the situation remains stressful for allergy sufferers.
