Debrecen's parks and the Tócó River corridor feature oak, linden, and acacia as the main tree pollen sources, with exposure varying between green areas and the more built-up city centre. Surrounding Great Hungarian Plain farmland and the Hortobágy steppe contribute substantial grass and crop pollen, while the dry continental climate concentrates pollen dispersal during spring with minimal rainfall interruptions from May onwards.

How often is the Debrecen pollen forecast updated?

Does pollen in Debrecen 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 Debrecen 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 Debrecen, 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.
