After the rain, sunshine ensures an increase in loads!

Thursday and Friday will be wet and rainy in Styria. For pollen allergy sufferers, this means a long-awaited brief respite. The weather situation will improve again from Saturday, which means that the pollen count and the associated stress levels will increase again.

The grasses are in bloom from Semmering to Murau and Feldbach. In Styria, we have already spotted flowering representatives of grass tripe, smooth oat, foxtail grass and bluegrass . In the meadow aspect, dock and plantain are an additional burden.

The white flakes that are currently increasingly visible in the air are poplar cotton wool. It cannot cause allergic symptoms as it is not pollen but poplar seeds and seed hairs. As the flight of poplar cotton wool usually coincides with the flowering of grasses, symptoms are often wrongly attributed to poplar.

In the Styrian Alps, green alders are in bloom. The rain will limit their pollen count to their mountainous area of distribution. However, as soon as the sun comes out again and the catkins dry out, green alder pollen can be transported to the lowlands by a suitable wind current and cause additional pollution there.

Note: At the moment, a yellowish film can be found on the surface of many varnishes. This is pollen from conifers such as spruce, pine and fir trees, which is also often deposited as a yellow film on car roofs or window sills. From an allergological point of view, it is not a cause for concern.

Other types of pollen in the ambient air: umbellifers, elderberry, pine, robinia, roses, horse chestnut, sour grasses and cypresses. These are of minor allergological importance.
