Lying on the remote outer Trøndelag coast, Osen opens the pollen season with alder from March before birch peaks through May. Grass from surrounding coastal farmland peaks through June and July, while the Norwegian Sea coastal position means onshore winds can frequently disperse pollen and the subarctic Atlantic climate provides regular rainfall interruptions throughout the compressed spring and summer season.

Does pollen in Osen kommune come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. 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 Osen kommune based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Osen kommune, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
