On 25 June 2026, Grass is the dominant pollen source in Barcelona. willow, alder, birch, hazel, and cypress are not currently active.

Barcelona Horta-Guinardó & Labyrinth Park features the neighbourhood's characteristic pine and plane trees alongside the historic Laberint d'Horta park, where cypress, linden, and introduced ornamental species are the main pollen sources. The Collserola hillside above contributes substantial tree pollen, while grass peaks through April and May, cypress contributes from January through spring, and mugwort extends into September throughout this northeastern Barcelona park neighbourhood.

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 Barcelona, 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.
