Pollen warning service Upper Austria from 21 to 28 May 2025

The meadow aspect with grasses, dock and plantain continues to determine the current pollen load. While the main flowering of grasses is coming to an end in the warm lowlands of the central and Danube region and the pollen count is decreasing after mowing, the pollen count is focussed on the middle areas of the Mühlviertel and the foothills of the Alps

The alternation of humid and warm weather conditions, thunderstorm activity and rising winds can lead to regional and localised grass pollen load surges. With the exception of oak and conifers, tree blossom is largely over. Pine pollen leads to the conspicuous and annoying yellow pollen precipitation, which is, however, insignificant from an allergological point of view. In residential areas, walnut, horse chestnut, elder and black locust trees are in bloom, while in the Alps the blossoming of green alder can cause localised irritation.
