Pollen information for Tyrol from 4 July 2025

Allergy risk from grasses increases with altitude!

Grass pollen. The grass pollen season is gradually easing in the lower-lying valleys of Tyrol. On warm and dry days, however, pollen concentrations can still reach moderate levels and cause allergic symptoms. At higher altitudes (above 1500 metres), for example in Galtür and Obergurgl, the picture is different: Here, the grass pollen season is currently reaching its peak, with moderate to high allergen levels - especially in meadows and pastures with dense grass vegetation. These areas can lead to a significant increase in allergic symptoms. In addition to grass pollen, plantain and dock pollen are also in the air, which further increases the burden for allergy sufferers.
The current and upcoming rainy phases can provide short-term relief as they temporarily wash the pollen out of the air. Thunderstorms, on the other hand, can exacerbate the situation: Sudden changes in humidity and air pressure break up pollen into tiny particles that can penetrate deep into the lungs and trigger severe reactions or asthma attacks. Allergy sufferers should stay indoors during thunderstorms if possible and keep windows closed to minimise exposure to allergens.

Green alder. The green alder pollen season is coming to an end and only small amounts are still measurable in the air.

Sweet chestnut. Sweet chestnut pollen is currently detectable in the region, but the overall exposure remains low. People with birch pollen allergies should be aware that cross-reactions with sweet chestnut pollen are possible.

Other types of pollen. Pollen from pine, cypress, lime, nettle and sedge are also currently measurable, but are only of minor allergenic significance.

Fungal spores. The concentration of fungal spores is currently in the moderate to high range. Sensitive persons may show allergic reactions.
