How to connect?

Oosterhout's Mark River corridor 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 city centre. Surrounding North Brabant farmland and the Mastbos woodland contribute substantial tree and grass pollen, while the flat, open landscape allows pollen to disperse readily across the city under prevailing westerly winds.

How often is the Oosterhout pollen forecast updated?

Does pollen in Oosterhout 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 Oosterhout 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 Oosterhout, 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.
