Trnava's historic urban green spaces and the Trnávka River corridor feature oak, birch, and linden as the main tree pollen sources in this flat South Slovak city. Surrounding lowland farmland contributes substantial grass and crop pollen, while the flat, open landscape allows pollen to disperse widely and ragweed extends the season strongly into autumn under the continental climate.

Does pollen in Trnava 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 Trnava 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 Trnava, 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.
