Portimão's Arade River estuary and the Atlantic coastal setting feature umbrella pine, carob, and introduced trees as the main pollen sources in this Algarve port city. Surrounding farmland and the Serra de Monchique woodland contribute substantial tree and grass pollen, while the Atlantic-Mediterranean coastal position means onshore winds can periodically disperse pollen and the dry Algarve summer concentrates the season in spring.

How often is the Portimão pollen forecast updated?

Does pollen in Portimão 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 Portimão 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 Portimão, 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.
