In Carinthia the ash trees are flowering, the cold weather hinders pollen release!

The pollen release of grey alder, black alder and hazel is largely complete for the 2026 vegetation year. Only in climatically unfavourable locations can small amounts of pollen grains from these early bloomers still be released into the air.

The pollen count of the ash. In climatically favoured locations, flowering has already begun, but will be significantly dampened in the coming days by a cold front with forecast precipitation. With the subsequent improvement in the weather, however, it is to be expected that the pollen release of the ash tree will begin quickly and in full.

The male flower catkins of the birch are currently still closed, even in climatically favoured locations. Therefore, there will be no significant allergic exposure to birch pollen over the next few days. However, with the rise in daytime temperatures, the flowering period will begin quickly, meaning that the first birch pollen can be expected to trigger allergic reactions around the Easter weekend. Due to low pollen production in the previous year, an above-average release of birch pollen must be expected this year.

There are also small amounts of pollen from poplars, elms, cypress plants, willows and yews in the air. However, these are only of minor allergological significance.
