Gondomar's parks and the Douro 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 suburban areas. Surrounding Portuguese Minho woodland and farmland contribute substantial tree and grass pollen, while the Atlantic-facing position means frequent onshore westerly winds and rainfall provide regular interruptions to exposure throughout.

How often is the Gondomar pollen forecast updated?
The Gondomar pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Gondomar 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 Gondomar 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 Gondomar, 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.
