Queluz's urban green spaces and the Jamor River corridor feature pine, oak, and eucalyptus as the main tree pollen sources, with exposure varying between these areas and the densely built suburban city centre. Surrounding Portuguese woodland and farmland contribute substantial tree and grass pollen, while the Atlantic-facing position means onshore westerly winds and frequent rainfall provide regular interruptions to exposure throughout.

How often is the Queluz pollen forecast updated?

Does pollen in Queluz 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 Queluz 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 Queluz, 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.
