Leganés' urban green spaces and the Butarque River corridor feature oak, pine, and ash as the main tree pollen sources, with exposure varying between these areas and the densely built suburban city centre. Surrounding Madrid regional farmland and the semi-arid Meseta landscape contribute substantial grass and crop pollen, while the continental climate concentrates pollen dispersal during spring under prevailing southwesterly winds.

Does pollen in Leganés 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 Leganés 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 Leganés, 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.
