Velsen-Zuid's North Sea Canal corridor and coastal dune green spaces feature oak, birch, and alder as the main tree pollen sources, with exposure varying between these areas and the more built-up industrial city areas. Surrounding North Holland farmland and the coastal dune landscape contribute substantial grass and tree pollen, while the North Sea canal and dune position mean onshore winds frequently disperse pollen.

How often is the Velsen-Zuid pollen forecast updated?

Does pollen in Velsen-Zuid 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 Velsen-Zuid 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 Velsen-Zuid, 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.
