Situation and medium-term forecast

Unstable weather conditions are causing changing allergenic burden!

After a week of sunshine and intense allergenic burden the weather forecast for the next days does not predict conditions that are ideal for pollination. This is caused by the expected rainfalls that will effectively wash pollen out of the air in many parts of the country. These are good news especially for grass pollen allergy sufferers who can expect reduced allergenic burden.

Currently orchard grass, meadow grass, false oat-grass, brome grass and ryegrass are responsible for the grass pollen in the ambient air.
In addition to the grasses dock and plantain are flowering as well and may increase the allergenic burden for grass pollen allergy sufferers.

The flowering period of oak is coming to an end. However, at some areas the pollen concentrations still reach low to moderate levels, but a decreasing trend may already be observed.

The onset of the flower of green alder has to be 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.

The development of fungal spores benefits from the current weather conditions. Therefore, increasing fungal spore concentrations must be expected but they will still remain at low to moderate levels.

What else: The pollen spectrum contains pollen of sedges, horse chestnut, elderflower, fir, spruce, cypresses and yews.
