Alcobendas' urban green spaces and the Jarama River corridor feature oak, pine, and ash as the main tree pollen sources, with exposure varying between these areas and the more built-up suburban city centre. Surrounding Castilian farmland and the semi-arid Meseta landscape contribute substantial grass and crop pollen, while the dry continental climate concentrates pollen dispersal during the spring season.

How often is the Alcobendas pollen forecast updated?

Does pollen in Alcobendas 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 Alcobendas 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 Alcobendas, 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.
