Aveiro's pollen season runs from January through June, opening with pine and oak tree pollen in late winter before grass pollen from surrounding Portuguese farmland and eucalyptus woodland peaks through April and May. The Ria de Aveiro lagoon position means onshore Atlantic winds can periodically disperse pollen, while the coastal setting keeps exposure lower than in more sheltered inland areas. The hot, dry summer ends the season abruptly from June onwards.

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.

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 Aveiro, 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.
