Set on the Osterøy island in the Osterfjord east of Bergen, Osterøy opens the pollen season with hazel and alder from February before birch peaks through April and May. Grass from surrounding island farmland peaks through June and July before mugwort extends exposure into September. The Osterfjord island position means onshore winds can periodically disperse pollen, while the very wet Bergen-area Atlantic climate provides very frequent rainfall interruptions throughout.

Does pollen in Osterøy 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 Osterøy 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 Osterøy 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.
