Situation and medium-term forecast for

Issued on July 11, 2024

Unstable weather conditions cause fluctuating exposure!

The grass pollen season is beginning to wind down, but in urban areas the flowering of mugwort is just around the corner.

The second half of the week will be dominated by changeable weather and heavy precipitation and thunderstorms are to be expected. Only from Sunday onwards will the sun appear more often and allow unrestricted pollen flight again.

Grass pollen allergy sufferers can breathe a sigh of relief, however, as the peak of the grass season has already passed and only low to moderate levels of grass pollen are to be expected. Although the values tend to reach higher levels with increasing altitude, peak levels are no longer to be expected.

Dock and plantain are still registered in small quantities.

As the grass pollen season winds down, however, the next stress phase for pollen allergy sufferers is already on the horizon: the flowering of the "weeds". This year, this begins again with the flowering of mugwort, which is already in bloom in some urban areas. At our measuring station, only a few pollen grains were registered, which do not yet indicate widespread flowering, but the first low levels may already be occurring locally.

The flowering of the green alder is coming to an end. Only rarely are pollen concentrations registered that exceed the irritation threshold for affected allergy sufferers.

Pollen from stinging nettle plants can still be detected in moderate to high concentrations in the air, but only poses a low risk from an allergological point of view.

Fungal spores are registered in moderate to high concentrations and can lead to intensive exposure, especially after rainfall.

Other less allergologically relevant types of pollen in the ambient air: rushes, lime, sour grasses and cypresses.
