The vegetation around Sint-Truiden, on the Haspengouw fruit-growing plain, is led by birch and plane among tree species, with grass and nettle pollen adding to seasonal totals from the surrounding Limburg land. Streets close to open ground typically see a different mix than the denser centre, particularly once the main tree pollen peak has eased off.

Does pollen in Sint-Truiden 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 Sint-Truiden 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 Sint-Truiden, 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.
