How to connect?

IJsselstein's urban greenery relies mainly on oak, birch, and linden, which dominate local tree pollen output, with exposure differing between the more built-up centre and the greener outskirts. Given IJsselstein's standing as a fortified polder town, the Hollandse IJssel river and nearby Utrecht farmland add noticeably to grass and tree pollen levels.

How often is the IJsselstein pollen forecast updated?

Does pollen in IJsselstein 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 IJsselstein 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 IJsselstein, 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.
