Santiago de Compostela's parks and the Sar River corridor feature oak, birch, and chestnut as the main tree pollen sources, with exposure varying between these green areas and the more built-up historic city centre. Surrounding Galician farmland and woodland contribute substantial tree and grass pollen, while the very wet Atlantic Galician climate means very frequent rainfall provides regular interruptions throughout the season.

How often is the Santiago de Compostela pollen forecast updated?

Does pollen in Santiago de Compostela 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 Santiago de Compostela 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 Santiago de Compostela, 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.
