Improved weather conditions are leading to increased pollution levels!

The Nova Rock Festival will take place in Burgenland from 11 to 14 June. You can find a detailed forecast under ‘Pollen levels for the Nova Rock Festival 2026’. 
After a mixed start to the week, the weather is set to improve by the weekend, with only Saturday likely to be marred by rain and thunderstorms. Consequently, higher pollen concentrations in the ambient air are to be expected in the coming days.
Flowering grasses remain the main cause of these levels. In addition to couch grass, brome grass, smooth oat grass, as well as honey grass, panicle grass, meadow grass, tufted grass and foxtail grass, these are responsible for the currently detectable grass pollen count.

In meadow areas, additional pollution from sorrel and plantain is also possible.

Significant amounts of pollen in the air are now also to be expected near cereal fields. Additional exposure may therefore occur near growing areas. However, as cereal pollen is quite large, it is not carried as far by the wind as the pollen of its naturally occurring relatives.

Regionally, people who are sensitive to olive tree pollen may need to expect low concentrations of olive tree pollen in the air.

Linden blossom has already passed its peak, but is still producing measurable pollen concentrations at our monitoring stations. As the flowers of this plant are adapted to insect pollination, they are generally quite rare in the air. However, the scent of the flowers can irritate the airways of sensitive individuals.

The Chinese toon tree, which is found in nutrient-poor and dry locations (such as railway embankments or wasteland), may already be releasing pollen. It is a neophyte from Asia that is spreading as an invasive plant in temperate or Mediterranean climate zones. Allergic skin reactions have already been documented.

Current weather conditions are conducive to the production and release of fungal spores. These have now reached moderate to high concentrations in the ambient air and can cause significant discomfort for allergy sufferers.

In addition to the pollen types mentioned, nettles, sour grasses, legumes, vines and cypresses are also currently present in the pollen spectrum. However, they pose only a very low allergenic risk.
