Birch pollen season declining, but pollen count remains moderate - grass pollen season ahead!

In the past week, pollen production and dispersal in Tyrol have remained at a high level. The weather conditions in the coming days will continue to favour the release and spread of pollen, although precipitation may only provide temporary relief for allergy sufferers from the middle of the week.

Birch pollen: The birch pollen season is now clearly on the decline. Pollen concentrations have fallen compared to the previous week and are currently mostly in the moderate range, although high levels may still occur locally. This downward trend is likely to continue in the coming days. Despite the decline, birch remains an important contributor to allergenic pollution. At the same time, the pollen concentrations of beech and oak are increasing and can reach high levels locally. Due to cross-reactions with birch pollen, these species can continue to trigger or intensify symptoms in people who are sensitised to birch pollen.

Grass pollen: Grass pollen is now regularly detected in the region. So far, the allergenic load is still low, but an increase in pollen concentrations is to be expected in the coming days. We are continuing to monitor developments closely, as grass pollen plays a key role for allergy sufferers as the season progresses.

Ash pollen: The concentrations of ash pollen are now predominantly low throughout the region, indicating that the ash pollen season is coming to an end.

Sycamore pollen: The sycamore pollen season is also coming to an end, with only low concentrations currently being measured.

Other pollen types: Pollen from spruce and pine is currently on the rise and currently makes up a large proportion of airborne pollen. Their characteristic yellow deposits are often visible on cars, window sills, garden furniture or in puddles. Although these types of pollen are not allergenic, they can cause mild irritation, such as a foreign body sensation in the eyes. In addition, pollen from horse chestnut, larch, walnut, cypress and willow have been detected, but these have a low allergenic relevance.

Situation at higher altitudes: At higher altitudes, the allergenic load remains low overall. However, birch pollen concentrations can already reach moderate levels locally.

Even if birch pollen concentrations decrease, the overall exposure to other pollen types and cross-reactions remains. This phase can continue to be challenging for allergy sufferers. Overall, the pollen count is expected to remain moderate, with beech, oak and grasses becoming more important in the coming days. The weather conditions favour the spread of pollen, with only temporary relief from the middle of the week due to periods of precipitation.
