Changeable weather brings fluctuating pollen counts!

The second half of the week starts with changeable weather. Precipitation is to be expected in the west of Austria in particular in the coming days, but thunderstorms and corresponding precipitation may also occur in the south. If the precipitation is more intense, pollen can be effectively washed out of the air. This will primarily benefit people who are sensitive to grass pollen are sensitised to grass pollen.

This is because tree pollen now only plays a subordinate role. Although there are still low levels of birch pollen, especially at higher altitudes birch pollen or their relatives such as beech and oak However, grasses are becoming increasingly dominant in the pollen spectrum.

The main culprits for the current grass pollen loads are panicle grasses, couch grasses, tufted grasses and foxtail grasses. According to our modelling, the grasses should already have reached flowering readiness in most regions. Due to the lack of precipitation in April, this year's grass pollen season is expected to be slightly below average to average in intensity.

In the meadow aspect, additional burdens from dock and plantain are possible.

Note: A yellowish film of dust can currently be found on car roofs or window sills. This is pollen from conifers such as spruce, pine and fir trees. From an allergological point of view, it is not relevant. However, as this pollen is present in high concentrations in the ambient air, it can cause mechanical irritation of the conjunctiva and respiratory tract.

The white flakes in the air are the seeds and seed hairs of the poplar. Their flight usually coincides with the beginning of grass flowering, but unlike grass pollen, they cannot cause allergic symptoms.

People who are sensitised to the pollen of olive trees must continue to expect symptoms in the coming days due to the flowering of the manna ash.

Oilseed rape is in bloom in rural areas. To avoid possible symptoms, pollen allergy sufferers should avoid being near these fields.

The lime trees that are often planted in gardens lime trees which are often planted in gardens, are also about to bloom and may start flowering in the coming days if the conditions are right. Their flowers are adapted to insect pollination and are therefore rarely found in the air, although the scent of the flowers can irritate the airways of sensitive people.

In addition to the pollen types mentioned above, umbellifers, mulberry, horse chestnut and mulberry are also currently in bloom, horse chestnutsour grasses, walnut and cypress plants are represented in the pollen spectrum. However, they only have a very low allergenic potential.
