Grass pollen comes next in May and June. Grasses grow everywhere in Hammerfest, even in parks and backyards. Their pollen floats in the air.
In July and August, pollen from weeds and docks appears. These plants grow in open areas and along roads. Their pollen can still cause problems.
In September, some trees produce pollen again. This season is smaller than the birch pollen season. The amount of pollen varies from year to year.
