This is the last pollen report of the 2023 season.

Pollen season has ended. Long-range transported ragweed pollen is not expected to reach Finland.

Mould spore quantities have reduced to a permanent low level. 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.
