Granollers' Congost and Besòs river corridors and surrounding suburban green spaces feature oak, pine, and plane as the main tree pollen sources. The Montseny massif to the north is a particularly significant regional tree pollen source, while surrounding Catalan pre-coastal farmland contributes grass pollen and the Vallès Oriental valley channels airflows under prevailing northerly winds throughout.

Does pollen in Granollers 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 Granollers 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 Granollers, 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.
