How to connect?

Schiedam's Nieuwe Maas River waterfront and surrounding green spaces feature oak, birch, and linden as the main tree pollen sources, with exposure varying between these areas and the more built-up port city centre. Surrounding South Holland farmland and the flat, open polder landscape contribute substantial grass and crop pollen, while waterway winds can periodically disperse pollen across the area.

How often is the Schiedam pollen forecast updated?

Does pollen in Schiedam 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 Schiedam 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 Schiedam, 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.
