Spring is returning - birch pollen season is just around the corner!

After the wintry conditions and snowfall of the past few days, the weather in Tyrol is now turning back to spring. Sunny and warmer conditions are expected for the coming days, at least until Thursday. These conditions favour pollen production and dispersal throughout the region.

We are now entering a new phase of the pollen season. Early bloomers such as alder and hazel have largely finished flowering, especially in the valleys. At higher altitudes, small amounts of hazel pollen may still occur in isolated cases. Overall, the allergenic load from these species is now very low.

Ash pollen: The ash is now the dominant allergenic pollen type. Moderate concentrations have already been measured at some locations. While pollen release was temporarily reduced during the recent cold and snowy phase, it will increase again with the return of mild and sunny conditions. The coming days could mark the peak of the ash pollen season.

Birch pollen: Some birch catkins are now reaching maturity and the first pollen release can be expected in the coming days. This should mark the start of the birch pollen season in the region. Allergy sufferers who are sensitised to birch pollen should be prepared for increasing pollen concentrations, which can lead to moderate allergen exposure. The hornbeama tree often found in gardens and parks, is also beginning to flower. Its pollen increases and can intensify allergic symptoms due to cross-reactions with birch pollen.

Other types of pollen: Pollen from poplar, elm, willow and from the family of cypress family are still present in the air, but have a low allergenic relevance.

Situation at higher altitudes: At higher altitudes, the development of vegetation is still delayed compared to valley locations. Pollen release is still limited there and the allergenic risk remains low.

Outlook: With the expected stable, mild and sunny weather conditions, pollen concentrations will increase overall in the coming days, mainly due to ash and the start of the birch pollen season. This marks the start of a more active phase of the pollen season. We will continue to provide you with regular updates to help you manage your exposure and symptoms as best as possible.
