Sistranda is a small Trøndelag coastal village in Frøya municipality on the Frøya island archipelago where birch, coastal grassland, and limited scrubland are the main local pollen sources. The Norwegian Sea island position means strong onshore winds very frequently disperse pollen, while the subarctic Atlantic climate produces a compressed season with birch peaking through May before grass contributes through June and July throughout this outer Trøndelag island community.

Does pollen in Sistranda 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 Sistranda 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 Sistranda, 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.
