Current pollen report for Tyrol
June 20th 2025
From valley to summit: grass pollen season is in full swing!
Grass pollen. As in the previous week, moderate to high grass pollen levels are being observed throughout Tyrol. What’s new this week is that all elevation zones, from valleys to alpine areas, are now affected. In Obergurgl, pollen levels have reached moderate allergenic intensity, while Galtür is experiencing high levels. In certain areas, particularly meadows and pastures with dense grass cover, the allergenic burden can become very high, as these local hotspots typically record the highest pollen concentrations. In addition to grass pollen, plantain and dock/sorrel pollen are also present in the air, potentially worsening allergic reactions during this period. We are now at the peak of the grass pollen season in Tyrol, with no altitude spared. As a result, many individuals with grass pollen allergies are reporting strong symptoms across the region. Those affected should take special precautions, such as limiting time outdoors during dry, windy days and following medical advice. Only rainy spells offer short-term relief, as they help to temporarily clear pollen from the air.
Green alder. Green alder (Alnus viridis) is still in bloom at higher elevations, but we are now observing a decreasing trend in pollen levels. While moderate concentrations may still occur locally, the allergenic burden is expected to continue declining in the coming days, as the peak of the green alder pollen season has passed.
Other pollen types. We are also observing pollen from spruce, pine, cypress family, elderberries, lime, stinging nettle, and sedges, among others, but these have low allergenic significance.
Fungal spores. Fungal spore concentrations are currently reaching moderate levels in valley areas. For sensitive individuals, exposure may trigger allergic reactions.
Pollen and thunderstorms: a risk for allergy sufferers. During thunderstorms, sudden changes in humidity and pressure can break pollen grains into tiny fragments that are easily inhaled deep into the lungs. This can trigger severe allergic reactions or asthma attacks, a phenomenon known as thunderstorm asthma. While rainfall usually helps wash pollen from the air, offering short-term relief, allergy sufferers should stay indoors and keep windows closed during storms to reduce the risk.
