Situation and medium-term forecast from 18th until 24th of June 2018

Moderate burden from grass pollen in the lowlands and high burden in higher elevated regions!
The flower of grasses is above average this year. Fortunately, the burden is decreasing in the lowlands since a while and stays widespread on a moderate level. However, temporarily increased concentrations may occur due to long distant transport of grass pollen especially during wind from the North. A higher burden has still to be expected in higher elevated regions. Grass pollen allergy sufferers may find better conditions at and above the timber line and in dense deciduous forests.
Ryegrass, false brome, timothy grass and golden oatgrass flower among the grasses. Grass species flower now as well in shaded areas. The fast and parallel flower of these and other grass species is unusual and characterizes this year´s grass pollen season.
Grass pollen allergy sufferers should avoid flowering meadows, because the local burden is higher there. The burden is lower where it was mowed.

Dock and plantain flower.

The flower of green alder fades in higher elevated regions. Green alder pollen might concern alder and birch pollen allergy sufferers.

Sweet chestnut is flowering. Its pollen might induce discomforts in some birch pollen allergy sufferers due to cross-reaction.

Pollen concentrations of the nettle family (e.g. stinging nettle) increase.
Plants of the goosefoot family flower and are found especially on wastelands and weed fields.

What else: The pollen spectrum contains pollen from linden, privet, the goosefoot and the nettle family in addition, which is of a low allergological importance.

Fungal spores occur in high concentrations in the air in the lowlands due to the warm and humid weather. The summery weather has caused a much earlier occurrence of a high burden than on average this year.
