Oldenzaal's parks and green spaces are dominated by oak, birch, and linden as the main tree pollen sources, though the gap between centre and edge can be considerable depending on wind direction. the Twente hill country near the German border and the surrounding Overijssel farmland add substantial grass and tree pollen to the mix, especially given Oldenzaal's role as a hilltop border town.

Does pollen in Oldenzaal 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 Oldenzaal 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 Oldenzaal, 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.
