Fungal spores are floating through the air, whilst an easterly wind is bringing ragweed pollen! 

Thursday’s rainfall has brought some relief to those with pollen allergies. Due to the rainfall, the concentration of fungal spores in the air will rise briefly on Friday, but will then drop slightly again over the weekend. The weekend will be sunny and dry, with an easterly wind. This may lead to increased long-distance transport of ragweed pollen in Burgenland. This could once again increase the local ragweed pollen load, which had been declining. In Burgenland, the pollen season for most herbaceous allergenic plants – such as grasses, stinging nettles, plantains and goosefoot plants – is already well advanced. These are now usually only detectable in small quantities in the ambient air.

Local ragweed populations in Burgenland may continue to cause moderate levels of pollen exposure. As easterly winds are expected to prevail over the coming days, there is a possibility of significant long-distance transport of ragweed pollen from our neighbouring countries. 

The fine weather is encouraging the flowering of annual mugwort and Kamchatka mugwort. Both species are late-flowering and occur naturally and as cultivated plants in Burgenland. They may still cause symptoms locally. As mugwort and ragweed both belong to the Asteraceae family, cross-reactions are possible.

Pollen from cannabis plants, impatiens and ivy are also present in the pollen spectrum. However, they pose only a low allergenic risk.
