Set along the Vågsjøen and Tjeldsund coast in south Troms, Harstad opens the pollen season with alder from March before birch peaks through May. Grass from surrounding farmland peaks through June and July, while the 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 in this North Norway regional centre.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

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