Situation and medium-term forecast

 

Sunshine keeps the allergenic burden at high levels!

As expected also the second half of the week will be dominated by sunny and dry weather conditions. Therefore, also the allergenic burden is expected to remain at high levels. Only in the Western parts of the country rainfall and thunderstorms are predicted for Saturday which locally results in a relief for pollen allergy sufferers.

Even though most of the grasslands have already been mowed, high burden caused by grass pollen has to be expected for the rest of the week. But the end of the peak pollination period is already in sight. While orchard grass already passed its peak, ryegrass is currently in full bloom and therefore responsible for the majority of the airborne grass pollen concentration. In addition, meadow grass, false-oat grass, fescue, and oat grass are flowering but already passed the peak flowering period as well. Grass pollen allergy sufferers should avoid freshly mowed areas due to high amounts of free allergen in the air.

Dock and plantain are still flowering and may increase the burden of grass pollen allergy sufferers.

Despite the green alder already passed the peak of its flowering period, allergy sufferers sensitized to alder or birch pollen may still experience allergenic burden at higher elevations.

Nettle is flowering and already reaches low to moderate concentrations. But its pollen is only of minor allergological importance.

Linden is flowering. Since this plant is insect pollinated its pollen is only of minor allergological importance, but the scent of its flowers may irritate some pollen allergy sufferers.

Privet is flowering as well. The pollen of this species is only of minor allergological importance but may cause symptoms due to cross reaction for people that are sensitized to pollen from the olive family.

Fungal spores reach moderate burden all across the country. Before thunderstorms the burden may rise even further.

What else: The pollen spectrum contains pollen from yews, cypresses, elder, pine and tree of heaven in addition, which is of a low allergological importance.
