How to connect?

Around Sittard-Geleen, oak, birch, and linden are the leading tree pollen contributors in parks and residential streets, with the leafier outskirts typically seeing higher counts than the compact centre. the loess hill country of South Limburg and the surrounding Limburg farmland add substantial grass and tree pollen to the mix, especially given Sittard-Geleen's role as a rolling loess-hill town.

Does pollen in Sittard-Geleen 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 Sittard-Geleen 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 Sittard-Geleen, 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.
