Situation and medium-term forecast
The main flowering period of mugwort has begun – burden from fungal spores remains high!
The main pollination period of mugwort has started. During sunny periods a moderate to high burden has to be expected. Mugwort occurs more frequent at weed fields, roadsides and dumps and thus higher pollen concentrations have to be expected here. Mugwort pollen allergy sufferers could evade into higher altitudes. Hardly any burden is expected at elevations of 1200 meters and above.
Attention during thunderstorms: Pollen could burst open during thunderstorms and release free allergen into the air, which may lead to a particular higher burden for some pollen allergy sufferers.
The late-blooming grasses continue to maintain a low allergenic burden. However, it does not concern all grass pollen allergy sufferers. Up to a moderate burden has still to be expected in higher elevated regions. Cornfields are in flower and should be avoided by grass pollen allergy sufferers. Intense pollination has to be expected in proximity to flowering fields due to the remarkable size of corn pollen.
Dock and plantain flower and may burden cause additional burden.
The ragweed pollen season start is expected in the last two weeks of August. In Burgenland, Vienna, Lower Austria, Styria, parts of Upper Austria, and Carinthia, locally burden from ragweed pollen may already occur. The majority of the plants are still developing, but immature inflorescences are partly present. You may report ragweed now also with the Ragweed Finder App! www.ragweedfinder.at
The pollen spectrum contains pollen from the nettle and the goosefoot family in addition, which is of low allergological importance.
The burden from fungal spores is favoured with hot and humid weather. Fungal spores occur in up to high concentrations in the air in the lowlands. We are in the period of the peak burden from fungal spores. The fungal spore concentrations are decreasing with elevation.
