Situation

12.9.2025

Flowering of grasses continues weakly, mainly on trimmed lawns. Small amounts of grass pollen can appear in the air near flowering plants.

The peak of ragweed flowering is in its northern growing areas in Central Europe. Long-range transported ragweed pollen is expected to reach the whole country. Pollen counts are mostly low, but can occasionally rise higher.

Rain reduces pollen levels in the air.

Airborne mold spore concentrations of the Cladosporium and Alternaria fungi are abundant in the whole country, Lapland excluded. In Lapland, concentrations may occasionally be moderate.
