Oitavos Dunes' Cascais Atlantic coastal setting features marram grass, stone pine, and coastal scrub as the main pollen sources across the natural dune links, with exposure varying between the exposed dune ridge fairways and the more sheltered valley holes. The Atlantic coastal position means onshore winds frequently disperse pollen, while the Sintra Mountain backdrop contributes additional tree pollen and the Atlantic climate provides regular rainfall interruptions throughout.

How often is the Lisbon pollen forecast updated?

Does pollen in Lisbon 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 Lisbon 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 Lisbon, 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.
