Situation and medium-term forecast

Grass pollen causes intense burden!

The current trend of high allergenic burden caused by grass pollen continues throughout the second half of the week. This allergenic burden stretches from the lowlands to mid-altitude regions. Grass pollen allergy sufferers may find better conditions in higher altitude regions, at and above the timber line and in dense deciduous forests.
Fescue grasses, couch grass, ryegrass, and golden oatgrass flower among the grasses. 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.
Rye flowers and may affect or burden additionally grass pollen allergy sufferers in proximity to fields in growing regions.
Dock and plantain flower.

Green alder is flowering at higher elevated regions where it already causes low to moderate levels of allergenic burden. Pollen arrives in mostly a low amount also in the lowlands, but the main burden is found in mid- to high-altitude regions.

What else: The pollen spectrum contains also pollen from linden, wine, mulberry, elderflower, conifers and nettle as well as the carrot family.

Fungal spores will occur now in low to moderate concentrations in the air in the lowlands.
