Pollen forecast

19.10.2026

Pollen season has ended.

The concentrations of airborne Alternaria and Cladosporium mold spores are low. On warmer days, counts may occasionally soar to moderate and trigger reactions in the most sensitive persons. The concentrations will reach zero only with continuous night frosts and a snow cover.

The pollen season usually starts in January or February, when long-range transport hazel and alder pollen reach Finland.
