Pollen warning service Upper Austria from April 17 to 24, 2024

The exceptionally high pollen load of the past warm period is being weakened by the sustained cold snap. What is striking this year is the high pollen production of practically all early bloomers and the sometimes multi-phase flowering process. For example, a second wave of birch pollen is appearing in the lowlands, but is currently concentrated at medium altitudes in the Mühlviertel and the foothills of the Alps. Moderate levels of ash can also still occur here.
Beech and oak and, in urban areas, sycamore and walnut are also flowering heavily. This also applies to the flowering of conifers, which forms a conspicuous and sometimes annoying yellow precipitate ("sulphur rain"). However, this is not allergologically significant. In the warmer and lower altitudes of the Alpine foothills and the Danube region, the flowering of individual grass species has already begun locally. However, due to the cool and damp weather, the impact remains low to moderate for the time being.
