Pollen warning service for Upper Austria from 28 May to 4 June 2025

After the predominantly humid weather, the meadow aspect with grasses, dock and plantain continues to determine the current pollen load. In the lowlands of the central and Danube region, the main flowering of the grasses is over and the levels are only moderate. The pollen load is centred in the middle altitudes of the Mühlviertel and the foothills of the Alps and shifts to higher altitudes as the temperature rises. The alternation of humid and warm weather conditions, thunderstorm activity and rising winds can lead to localised grass pollen exposure spikes. In the Mühlviertel region in particular, the allergenic rye in bloom increases exposure.
With the exception of the conifers, lime and robinia, as well as the elder bush, the tree blossom is largely over. Regionally, especially in the Mühlviertel, the blossoming of the Scots pine can still lead to the conspicuous and annoying yellow pollen precipitation, which is however insignificant from an allergological point of view.
In the Alps, green alder can cause irritation locally.
