Changeable weather is causing pollen levels to fluctuate!

The weather in Styria is set to be changeable over the coming days. During sunny spells, pollen levels may fluctuate between moderate and high. Where it rains, pollen concentrations drop, bringing some relief to allergy sufferers. As soon as the sun comes out again and the flower heads have dried out, pollen dispersal picks up pace once more.

Currently, early-flowering grasses are the main allergens in the Styrian air. The main culprits for pollen release are false oat-grass, false barley, annual meadow grass, vernal grass, cock's foot grass and foxtail grass. Even in the higher elevations of Styria, the grasses have already begun to flower. However, pollen concentrations here are currently still lower than in the lowlands. In meadows, sorrel and plantain species can intensify the pollen load. In addition, the first stinging nettles have begun to flower. 

In Styria, the flowering of oak and beech is coming to an end.

In the mountains, green alder is also flowering. During sunny spells, small amounts of pollen may be carried down into the lowlands. The main concentration of pollen will continue to be in the higher elevations.

Over the course of the week, the first allergy-relevant quantities of fungal spores may be present in the air.

In addition to the pollen types mentioned, umbellifers, elder, mulberry, black locust, horse chestnut, sour grasses, legumes, walnut and cypresses are currently also present in the pollen spectrum. However, they pose only a very low allergenic risk.
