Situation and medium-term forecast
Mugwort is in full bloom – the ragweed season moves closer!
There is a short-term weather-related relief in sight before Sunday, but pollination will be favoured again afterwards. Thus, the burden will vary within the next few days.
Mugwort is in its main flowering period and will burden increasingly under favourable weather conditions. Moderate values will be reached on a widespread scale. Mugwort will burden especially locally and in more concerned regions, like the East and South of Austria. Mugwort occurs more frequent at weed fields, fallow lands and dumps and thus its pollen has to be expected there. Mugwort pollen allergy sufferers should evade into higher altitudes. Hardly any burden is expected at a sea level of 1200 meters and above.
Attention during lightning-storms: 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 flower of grasses is fading. Only low grass pollen concentrations have to be expected also at higher altitudes. Dock and plantain continue to flower and may burden in addition.
The ragweed pollen season start is approaching. Scattered flowering ragweed plants may be encountered in the East of Austria. Only locally a low burden has to be expected for now. Here you can see the ragweed reports from 2020 and you can report your findings as well: www.ragweedfinder.at
A burden may occur on occasion due to long-distance transport of ragweed pollen in the East of Austria due to the more progressed flower of ragweed in the East and South of Europe. Such a situation is at the moment not on the horizon. The West of Austria is still a recommended region for ragweed pollen allergy sufferers.
The pollen spectrum contains pollen from hop, the parsley, the nettle and the goosefoot family as well, which is of low allergological importance.
Fungal spores may occur in up to high concentrations in the air. We are in the period of the peak burden from fungal spores. The fungal spore concentrations are decreasing with increasing elevation.
