Rosendal is a small Vestland village in Kvinnherad municipality on the Hardangerfjord at the foot of the Folgefonna glacier where birch, hazel, and fjordside orchard vegetation are the main local pollen sources. The Hardangerfjord position means onshore winds can periodically disperse pollen, while the Atlantic-influenced Hardanger climate provides frequent rainfall interruptions and birch peaks through April and May before grass and orchard vegetation contribute through June and July.

How often is the Rosendal pollen forecast updated?

Does pollen in Rosendal 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 Rosendal 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 Rosendal, 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.
