Ørsta's dramatic setting beneath the jagged Sunnmøre Alps combines birch woodland on the lower slopes with the region's very high precipitation, which tends to wash pollen out of the air more frequently than drier inland valleys.

From there, grass pollen continues through the June-July stretch. With the frequent Atlantic weather systems that reach this stretch of coast, the local climate means the timing can vary from what neighbouring districts experience.
How often is the Ørsta pollen forecast updated?

Does pollen in Ørsta 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 Ørsta 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 Ørsta, 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.
