Overview

• The national pollen service reports the flowering has started, and the pollen is regarded as highly allergenic.
• After recent warmth accelerated development, measurements show first clear burdens in Niederlausitz, marking southern Brandenburg as a hotspot.
• Bavaria recorded slightly elevated levels last week due to easterly winds carrying pollen from neighboring countries, according to the DWD.
• DWD expert Anke Kniffka says Ambrosia artemisiifolia is established in Germany, occurring mainly in the south, the southwest, southern Brandenburg and Hesse.
• Most regions currently see very low or sporadic pollen flight, and the season’s trajectory remains uncertain because distribution data are incomplete.
