Pola de Siero's Nora River valley and surrounding Asturian woodland setting feature oak, birch, and chestnut as the main tree pollen sources in this Asturian municipality. Surrounding woodland and farmland contribute substantial tree and grass pollen, while the Atlantic-facing Cantabrian position means very frequent rainfall provides regular interruptions and the Nora valley channels airflows throughout.

Does pollen in Pola de Siero 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 Pola de Siero 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 Pola de Siero, 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.
