The grass pollen season is gradually coming to an end in Tyrol – higher altitudes remain the main focus of pollen levels!

Over the coming days, the warm and predominantly dry weather in Tyrol is set to continue, although isolated rain showers may occur. Whilst grass pollen concentrations in the valleys and at medium altitudes are continuing to fall, allergy sufferers should remain cautious, particularly at higher altitudes, as the grass pollen season is still ongoing there.

Grass pollen: Grasses remain the dominant type of allergenic pollen in Tyrol. In the lower valley areas, grass pollen concentrations are continuing to fall as the flowering season for many grass species is gradually coming to an end. A similar downward trend is now also evident at medium altitudes (up to around 1,500 m), although moderate allergen levels may still occur locally. Above 1,500 m, however, the grass pollen season is still in full swing. Moderate pollen concentrations are still being recorded there, particularly in meadows, pastures and other grass-rich areas, where pollen production remains high. People planning leisure activities in these areas should therefore continue to expect allergy symptoms.

Plantain and sorrel pollen are also still present in the air. Although these types of pollen usually occur in lower concentrations than grass pollen, they can further exacerbate symptoms in sensitive individuals during the grass pollen season.

Sweet chestnut pollen: Small amounts of sweet chestnut pollen are still being detected. In Tyrol, sweet chestnut trees are mainly found in parks and gardens. As they are predominantly pollinated by insects, the majority of their pollen remains near the flowering trees. Although sweet chestnut pollen has only minor allergenic significance, cross-reactions with birch pollen have been reported. Consequently, isolated symptoms may occur in individuals who are sensitised to it.

Other types of pollen: In addition, pollen from pine, cypresses, lime, stinging nettle and sour grasses, amongst others, is being detected. These types of pollen are of only minor allergenic significance.

Fungal spores: Concentrations of fungal spores in the air remain in the moderate to high range across much of Tyrol. Periods of rain and the associated increase in humidity promote the growth of fungi and the formation of spores. People who are sensitive to fungal spores may therefore experience increased symptoms, particularly after rainfall.

Weather, pollen levels and practical advice: The warm and predominantly dry weather will continue to encourage pollen release over the coming days. Although isolated rain showers may reduce pollen concentrations in the short term, they usually provide only temporary relief. As the grass pollen season varies with altitude, pollen levels are currently often higher at higher altitudes than in many valley areas. People with allergies should bear this in mind when planning outdoor activities.
