How to connect?

Lying in the North Østerdalen valley near the Swedish border, Os in Innlandet opens the pollen season with hazel from February before birch peaks through April and May. Grass from surrounding farmland peaks through June and July before mugwort extends exposure into September. The elevated valley setting and the very continental border climate mean the season begins slightly later than in lowland Innlandet, while birch is particularly significant throughout.

Does pollen in Os 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 Os 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 Os 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.
