Gijón's coastal setting on the Cantabrian Sea features oak, birch, and eucalyptus as the main tree pollen sources in parks and along streets, with exposure varying between green areas and the more built-up city centre. Surrounding Asturian woodland and farmland contribute substantial tree and grass pollen, while the Atlantic-facing position means frequent rainfall provides regular interruptions to exposure throughout the season.

How often is the Gijón pollen forecast updated?

Does pollen in Gijón 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 Gijón 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 Gijón, 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.
