How to connect?

Sollentuna relies on spruce, birch, and oak in its parks and green belts as the principal tree pollen sources. Open fields near the surrounding lake and forest district north of the city let grass and crop pollen spread widely whenever conditions are dry and breezy. Sollentuna shows a vegetation pattern typical of Swedish towns its size, driven by nearby countryside rather than commuter residential development.

Does pollen in Sollentuna 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 Sollentuna 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 Sollentuna, 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.
