Virtually no local pollen in the air, but levels of fungal spores and ragweed carried from afar are possible!

Styria is set for a dry, sunny to slightly cloudy week, with temperatures around 20 °C. The flowering of herbaceous allergenic plants has largely come to an end, from the mountains down to the lowlands. This is also reflected in the fact that only very small amounts of ragweed, mugwort, grass, nettle and plantain pollen are now being detected at our monitoring stations. In Eastern and Southern Styria, southerly winds will predominate this week, which may lead to the long-distance transport of ragweed pollen. Although ragweed flowering is already well advanced in our neighbouring countries, a rise in pollen levels to a moderate level is still possible. Moderate levels of fungal spore dispersal are still possible in the coming days, and locally – for example in deciduous forests – levels may even reach high levels.

The flowering of annual mugwort and Katshka mugwort is also already well advanced. Both may continue to cause exposure locally. Canadian goldenrod is also still in flower. For allergy sufferers who are sensitised to mugwort or ragweed, Canadian goldenrod may trigger cross-reactions. Dense stands of these composite flowers should be avoided by sensitised individuals.

Pollen from cannabis plants, impatiens and ivy are also present in the pollen spectrum. However, they pose only a low allergenic risk.
