Situation and medium-term forecast
Mugwort pollen season continues – burden from fungal spores continuously high!
The flower of mugwort is now prevalent in the lowlands of Austria. A moderate burden has to be expected if weather conditions are favourable. Only low mugwort pollen concentrations prevail in the air in the next days due to the influence of a cold front. The period of the main burden and the full flower of mugwort is expected around the middle of August. Mugwort occurs more frequent at weed fields, roadsides and dumps and thus its pollen has to be expected there. Mugwort pollen allergy sufferers could evade into higher altitudes. Hardly any burden is expected at sea levels of 1200 meters and above.
Attention during thunderstorms: Pollen could split open during thunderstorms and release free allergen into the air, which may lead to a particular higher burden for some pollen allergy sufferers.
The grass pollen season is fading in the lowlands of Austria with a low burden, although this low level will be reached for a longer time due to late flowering grass species. However, it does not concern all grass pollen allergy sufferers. Up to a moderate burden has still to be expected in higher elevated regions and on occasion in the lowlands due to long range transport or the rebloom of some grass species.
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 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.
