Current pollen report for Tyrol

Grass pollen season underway – allergenic burden increasing across Tyrol!
Over the past days, unstable weather conditions and periods of precipitation have significantly reduced airborne pollen concentrations and the associated allergenic burden across Tyrol. These conditions are expected to continue until tomorrow. From Sunday onwards and during the coming week, weather conditions are forecast to become warmer, sunnier, and drier. This will strongly favour pollen production and dispersal, leading to increasing allergenic loads across the region. Overall pollen concentrations are expected to return to moderate levels and may locally reach high values.
Grass pollen: Grasses are now becoming the main allergenic factor across Tyrol. The grass pollen season is likely to fully start during the coming week. Grass pollen concentrations are expected to increase rapidly and may reach moderate to locally high levels, especially in valley bottoms and lower elevations. In addition to grass pollen, concentrations of plantain and dock/sorrel pollen are also increasing. Plantain pollen has a moderate allergenic potential and often affects individuals already sensitive to grass pollen. Dock and sorrel pollen are considered less allergenic but may still aggravate symptoms in people with grass pollen allergies. Together, these pollen types can intensify discomfort for allergy sufferers. At higher elevations, grass pollen concentrations remain considerably lower compared to valley bottoms, making these areas currently more favourable for individuals with grass pollen allergies.
Birch pollen: Birch pollen concentrations have now decreased substantially and mostly reach only low levels across the region. At higher elevations, where flowering is delayed, locally moderate allergenic burdens may still occur. Pollen concentrations from oak and beech are also continuing to decrease.
Green alder pollen: Green alder is now beginning its flowering period at higher elevations. Although the allergenic burden currently remains low, pollen concentrations are expected to increase gradually over the coming weeks.
Other pollen types: We are also detecting pollen from walnut, mulberries, horse chestnut, and the cypress family, but these currently have low allergenic significance. Pollen from spruce and pine remain abundant in the air and continue to produce characteristic yellow deposits on surfaces throughout the region. Although these pollen types are not allergenic, they may still cause mild irritation, such as a foreign body sensation in the eyes.
Pollen and weather conditions: Weather conditions play a crucial role in shaping pollen dynamics. They influence how much pollen is produced, when it is released, and how far it spreads. Rain generally limits pollen dispersal, while warm, dry, and sunny weather typically leads to elevated airborne pollen concentrations. Understanding these interactions is essential for accurate pollen forecasting and improved allergy management.
