Situation

1.9.2025

Grass and mugwort flowering remains weak in southern and central regions, mostly due to re-flowering. Grass pollen levels are low, mugwort levels very low in the air.
Ragweed pollen may drift into S and C Finland, especially on Thursday.
Cladosporium mould spores have occasionally reached high levels, Alternaria spores up to moderate levels, in southern areas of the country.
