Situation and medium-term forecast

The flower of grasses causes an intense burden!

A moderate to high burden from grass pollen will prevail during the course of this week in the lowlands. The burden is higher in the mid-altitude regions due to the delayed pollination period. 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, feather reed grass, creeping soft grass, oatgrass, brome grasses, orchard grass, and false-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.
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 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.
