Spread across Helgeland islands and coastal headlands, Herøy in Nordland opens the pollen season with alder from March before birch peaks through May. Grass from surrounding island farmland peaks through June and July, while the Norwegian Sea island position means strong onshore winds frequently disperse pollen and the subarctic Atlantic climate produces a compressed season with regular rainfall interruptions throughout.

Does pollen in Herøy 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 Herøy 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 Herøy 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.
