San Cugat del Vallés' parks and the Rubricatus torrent corridor feature oak, pine, and plane as the main tree pollen sources, with exposure varying between these green areas and the more built-up suburban areas. Surrounding Catalan pre-coastal farmland and the Collserola woodland contribute substantial tree and grass pollen, while the sub-Mediterranean climate concentrates pollen dispersal during spring with the Collserola ridge providing locally significant tree pollen.

Does pollen in San Cugat del Vallés come from nearby or far away?

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 San Cugat del Vallés 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 San Cugat del Vallés, 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.
