Grasses on the retreat, mugwort is becoming more dominant and ragweed is taking off in neighboring countries!

The flowering of grass es usually causes only minor problems! Mugwort pollen, on the other hand, is gaining in importance. Fungal spores are a heavy burden.

The weather forecast for the next few days suggests that the pollen count will change, at least on Sunday.
As most of the grass species in our area have already largely exhausted their flowering potential, only low levels of contamination are to be expected. In the outlying districts near maize fields, maize can cause additional stress for grass pollen allergy sufferers. However, due to the size of the pollen grains and the associated higher sinking speed, relevant exposure is generally only to be expected in the immediate vicinity of maize fields.

Mugwort pollen can lead to moderate pollution at an increasing number of locations. On a long-term average, it can be assumed that the mugwort bloom peaks in mid-August.

In addition, the first early-flowering ragweed plants have been sighted in the area around Vienna, meaning that ragweed allergy sufferers should avoid areas with ragweed growth. The first ragweed pollen can also be found in our pollen traps. This indicates an early start of flowering in our eastern and south-eastern neighboring countries. You should therefore pay attention to our hourly forecasts, as long-distance transport can also cause exposure at night.

Pollen from nettle plants is still present in relevant concentrations in the ambient air, but poses only a low risk from an allergological point of view.

Fungal spores, on the other hand, will benefit from the precipitation and continue to occur in high concentrations.

Other less allergologically relevant types of pollen in the ambient air: dock, rushes, goosefoot, sour grasses, plantain and cypress.

Ragweed pollen season is also just around the corner! If you would like to help us and other allergy sufferers to reduce exposure during this year's season, you can report ragweed populations in your area via the Ragweed Finder app or online at ragweedfinder.at!
