Situation and medium-term forecast

Snow and rain limit pollination!

Despite the sunshine, low temperatures only allow low pollination! After the rainy and snowy days of the past week, the weather forecast predicts sunshine for the following days. While sunshine is ideal for pollination, the low temperatures do not allow a lot of pollen in the air.
Therefore, low levels of allergenic burden caused by hazel pollen are expected in the lowlands and in sun-exposed locations. In many places, the catkins of native alder species are already showing significant progress in development, but still need a few hours of sunshine before they are ready to bloom.
If the weather situation does not change in the coming days, the allergenic burden may slowly start to increase towards the end of the week as more and more alder catkins may start to release pollen.

Note: Pollination from alder and hazel is favoured especially during sunny periods. Regions with frequent occurrence of hazel (edges of the forests) and alder (river-meadows) should be avoided when taking a walk.

What else: The pollen spectrum contains also pollen from cypresses and yews.

Note: The model results give an indication of the expected start of flowering, based on information provided by local pollen warning services with direct reference to the local situation. Start of flowering is not to be equated with the beginning of the pollen season. When the start of flowering is achieved, the majority of the plants have the potential to release pollen, but only when weather conditions are favourable.
