Unsettled weather continues to keep the pollen count low!

Even in the second half of the week, pollen allergy sufferers can expect mainly low levels of pollen, as rain can effectively wash the pollen out of the air. According to the weather forecast, the rain should only stop from Saturday afternoon. From then on, more intense pollen counts are possible again.

However, the pollution caused by the birch blossom will probably only reach low intensities even in fine weather, as many of the plants have already faded.

However, as beech and oak are also flowering at the moment, there may be additional pollution due to cross-reaction.

The sycamore tree continues to cause pollen dispersal and can lead to contamination, especially along avenues of sycamore trees or other large clusters of this tree species.

Pollen from manna ash and lilac can cause renewed exposure in people who are sensitized to olive trees. As both species are pollinated by insects, relevant pollen counts are only to be expected in the immediate vicinity of the plants.

The white flakes that are currently increasingly visible in the air are poplar absorbent cotton. It cannot cause allergic symptoms as it is not pollen but poplar seeds and seed hairs. As the flight of poplar absorbent cotton usually coincides with the beginning of grass flowering, symptoms are often wrongly attributed to poplar.

In the coming days,grass pollen will only cause minor symptoms locally in dry and sunny weather. This is because the first panicle, foxtail and tufted grasses are already flowering in some locations. However, according to our model data, it will still be early May before the grass pollen season begins across the board.

Allergy sufferers should avoid being near rape fields in bloom to prevent possible symptoms.

Other types of pollen in the ambient air: maple, boxwood, yew, mulberry, carnation, rose, horse chestnut, sour grass, walnut and cypress. These are of minor allergological importance.
