Vila Franca de Xira's parks and the Tagus River corridor feature oak, pine, and eucalyptus as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Portuguese farmland and the Tagus floodplain meadows contribute substantial tree and grass pollen, while the Atlantic-facing Tagus estuary position means onshore winds can periodically disperse pollen.

How often is the Vila Franca de Xira pollen forecast updated?

Does pollen in Vila Franca de Xira 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 Vila Franca de Xira 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 Vila Franca de Xira, 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.
