Zaragoza's parks, including Parque Grande and the Ebro River corridor, feature poplar, pine, and olive as the main tree pollen sources, with exposure varying between green areas and the more built-up city centre. Surrounding Aragonese farmland contributes substantial grass and crop pollen, while the dry continental climate and frequent Cierzo north wind disperse pollen widely across the city.

When is pollen season in Zaragoza?
Zaragoza's pollen season runs from February through June, opening with poplar and olive tree pollen in late winter before grass pollen from surrounding Aragonese farmland peaks through May and June. The dry continental climate and frequent Cierzo north wind can disperse pollen widely or concentrate it depending on conditions, while the hot, dry summer ends the season more abruptly than in Atlantic-facing Spanish cities.
How often is the Zaragoza pollen forecast updated?

The Zaragoza pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Zaragoza 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 Zaragoza 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 Zaragoza, 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.
