Situation and medium-term forecast
Sunny weather favours the flower of grasses!
The grass pollen concentrations were mostly moderate due to the rainfalls. Sunny and warm weather is forecasted for the next few days. Thus, up to a high burden from grass pollen has to be expected in the valleys, lowlands and basins. Rainfalls may decrease pollen concentrations short-term for certain days in the long run.
Meadow grass, orchard grass, false-oat grass and brome grasses flower among the grasses. Grass pollen allergy sufferers should avoid flowering meadows, because the local burden is higher there. The burden is lower where it was mowed.
Grass pollen allergy sufferers will find good conditions in mid altitudes, at or above the timber line as well as in dense deciduous forests.
Cultivated rye flowers and may affect or burden additionally grass pollen allergy sufferers in proximity to fields in growing regions.
Dock and plantain flower.
The white flakes floating in the air are poplar wool, which itself does not irritate. It is just the seed and seed hair from poplar. However, irritation is often wrongly attributed to it because the occurrence of poplar wool usually coincides with grass pollination. However, it occurs earlier in the air this year.
Currently flowering rapeseed fields should be avoided by concerned pollen allergy sufferers.
The onset of the flower of green alder has to be expected in higher elevated regions and areas of growth. Pollen arrives in mostly a low amount also in the lowlands, but the main burden is found in mid- to high-altitude regions. Green alder pollen might concern alder and birch pollen allergy sufferers.
The “Sulphur sediment” is noticeable: Yellow sediment can be found on water surfaces, smooth surfaces and window panes. This sediment derives now from conifer pollen (pine, spruce), which may be annoying, but does not cause an allergic burden.
What else: The pollen spectrum contains pollen from oak, walnut, horse chestnut, spruce, pine, elder and sedges in addition, which is of a low allergological importance.
Fungal spores may occur in relevant, but for now only low concentrations in the air in the lowlands during fair weather periods.
