In the lowlands, hazel and alder are ready to bloom, but the weather only allows a small amount of pollen to fly!

The wintry weather conditions are not yet giving in and are once again ensuring that the pollen count cannot pick up speed in large parts of Austria this week. Pollen allergy sufferers can therefore look forward to a few more days of relief.

In the Alpine region in particular, pollen counts from hazel and alder are unlikely in the coming days due to the expected precipitation, although many of the plants already have catkins that are ready to flower.

However, the renewed drop in temperature and precipitation will also bring relief to the rest of the country. However, if the weather situation changes locally (sunny and dry), there may still be low to moderate levels in the lowlands.

The hazel pollen concentrations currently measured originate both from the tree hazels, some of which are slightly above average with catkins this year, and from the shrub hazels, which are also well populated with catkins.

In terms of alder pollen concentrations, the focus has shifted from the flowering of the purple alder to the grey alder. A slightly above-average number of catkins was observed in both the grey alder, which is native to this country, and the black alder, which begins to bloom somewhat later. In the coming days, depending on the weather, low to moderate loads can be expected. If, contrary to expectations, it turns out to be sunnier and warmer than forecast, higher levels of stress may also occur in the short term in climatically favoured locations.

In the flowering readiness model, a number of state capitals are already defined as ready for flowering. However, flowering readiness is not to be equated with pollen release. It merely means that the catkins are sufficiently developed to be able to release pollen under suitable weather conditions.

In addition to the pollen types mentioned above, the following are also represented in the pollen spectrum: Cypress plants. However, they only have a very low potential for causing allergic reactions.
