Lying along the Helgeland coast near Sandnessjøen, Alstahaug opens the pollen season with alder from March before birch peaks through May. Grass from surrounding farmland peaks through June and July, while the Norwegian Sea coastal position means onshore winds can periodically disperse pollen and the subarctic Atlantic climate provides regular rainfall interruptions throughout the compressed spring and summer season.

A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Alstahaug kommune based on measurements or forecasts?
