Situation and medium-term forecast
From the lowlands up to the high elevations high grass pollen burden can be expected – the weed pollen season is approaching!
This week, dry and sunny weather will provide ideal conditions for pollen and fungal spore release. Only in western Austria rainfalls will deliver short-term relief for pollen allergy sufferers at the beginning of the week.
Remark: A weather situation with thunderstorms may lead to a particular intensive burden because pollen could burst open during thunderstorms and release free allergen into the air.
The sunny and dry weather conditions of the coming days may lead up to high grass pollen burden at middle to high elevations of the Alps. Even in the lowland regions where the peak flowering season of the grasses has already passed high pollen concentrations may be possible. Grasses home to forested habitats are slowly reaching their readiness to flower and may a cause allergenic burden to highly sensitive grass pollen allergy sufferers. Yellow oat grass, cock’s-foot grass and ryegrass flower among the grasses.
The bloom of privet and sweet chestnut are fading in the gardens and parks of Austria. Only weak allergenic potential remains nearby these trees and bushes.
Members of the nettle and goosefoot families are currently in full bloom. Their pollen is only of low allergological relevance.
Besides the main aeroallergens the following pollen types were registered in the pollen spectrum: cypresses, tree of heaven, lime tree and privet.
For the coming week moderate to high fungal spore concentrations in the air can be expected.

Forecast from 06.07.2020
Note: The model results give an indication of the expected start of flowering, based on information provided by local pollen warning services with direct reference to the local situation. Start of flowering is not to be equated with the beginning of the pollen season. When the start of flowering is achieved, the majority of the plants have the potential to release pollen, but only when weather conditions are favourable.
