Birch flowering has mainly ended in the Southwest Finland and Uusimaa, but birch pollen is transported there from the rest of the flowering area. Flowering diminishes in the central parts of the country. Flowering continues in rest of the country, central and northern Lapland excluded. The amounts of birch pollen are abundant in the flowering area.

Grasses are flowering in the southern parts of the country. Grass pollen levels are still very low.

Conifer flowering has begun in the southern parts of the country. Conifer pollen sets on surfaces forming a yellow layer, but causes allergic reactions to very few.

Alder flowering continues with low pollen counts in northern Lapland.
