Hilversum's distinctive setting within the Gooi heathland and woodland means oak, birch, and pine are the dominant tree pollen sources, with exposure varying considerably between the surrounding heathland and the more built-up city centre. The Gooi landscape is a particularly significant local pollen source, while surrounding North Holland farmland adds additional grass pollen exposure.

How often is the Hilversum pollen forecast updated?
The Hilversum pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Hilversum 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 Hilversum 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 Hilversum, 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.
