Early summer weather allows lots of pollen!

Sunny weather is forecast throughout Austria over the next few days with daytime highs well above 20°C. Only in the west will showers and thunderstorms cloud the weather in the evening hours. During the day, a strong allergic reaction to pollen is therefore to be expected throughout the country.

The birch season is coming to an end in the west and south of Austria. Relevant pollen concentrations in the ambient air are now only rarely registered. In the higher elevations of western Austria, relevant pollen counts and moderate to high concentrations are still to be expected.

However,birch pollen allergy sufferers in the east and south cannot yet breathe a sigh of relief, as the beech, oak and walnut trees that are still in bloom can still cause allergic reactions due to cross-reactions.

Pollen from hornbeam and hop hornbeam, which also cross-react, is usually only registered in very small quantities at the measuring stations and therefore only rarely plays a relevant role.

The main bloom of the sycamore tree has ended. Allergic exposure can only occur in the immediate vicinity of larger stands In urban areas, people who are sensitized to the pollen of olive trees may be exposed again. This is due to the currently flowering manna ash. However, like the lilac, this plant is pollinated by insects and therefore only leads to relevant pollen concentrations in the immediate vicinity of the plant.

Grass pollen can lead to the first low to moderate levels in the next few days. However, these are currently still localized. According to the data from our flowering readiness model, more widespread exposure is not expected until the end of the week. At the moment, foxtail grasses, tufted grasses, rank grasses and bluegrasses in particular are ready to flower.

In the meadow aspect, dock, which blooms in places, can represent an additional burden.

In some regions of the country, rape is in flower. To prevent possible symptoms, allergy sufferers should avoid being near these fields.

Other types of pollen in the ambient air: maple, boxwood, yew, mulberry, carnations, roses, horse chestnut, sour grasses and cypresses. These are of minor allergological importance.
