Oviedo's Parque de San Francisco and the Nalón River headwaters corridor feature oak, birch, and chestnut as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Asturian woodland and farmland contribute substantial tree and grass pollen, while the Atlantic-facing Cantabrian position means very frequent rainfall provides regular interruptions throughout the season.

How often is the Oviedo pollen forecast updated?

Does pollen in Oviedo 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 Oviedo 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 Oviedo, 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.
