Colmenar Viejo's Sierra de Guadarrama foothills setting and the Manzanares River headwaters feature oak, pine, and ash as the main tree pollen sources, with the Guadarrama woodland and heathland particularly significant locally. Surrounding Madrid regional farmland extends grass pollen, while the elevated setting creates distinct pollen patterns compared to lower-lying areas of the Madrid metropolitan region.

Does pollen in Colmenar Viejo 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 Colmenar Viejo 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 Colmenar Viejo, 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.
