Situation and medium-term forecast
Moderate to high burden from grass pollen!
The peak burden from the flower of grasses has shifted to mid-altitude regions. Still high values due to grass pollen have to be expected there. The flower of grasses burdens in a moderate extent in the lowlands on a widespread scale, but increased values are possible occasionally during favourable conditions.
Timothy grass, creeping soft grass, bent grasses, couch grass, ryegrass, false brome and golden oat grass 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 better conditions in high altitudes at or above the timber line as well as in dense deciduous forests.
Dock and plantain flower and may burden in addition.
Sweet chestnut is flowering. Its pollen might induce discomforts in some birch pollen allergy sufferers due to cross-reaction.
The onset of the flower of green alder has to be still 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.
What else: The pollen spectrum contains pollen from linden, elder, tree of heaven and the nettle family in addition, which is of a low allergological importance.
The burden from fungal spores is favored with hot and humid weather. High values are attained in the lowlands on a widespread scale. The burden decreases with the altitude.
