Den Helder's North Sea coastal dune landscape and the Marsdiep waterway feature oak, birch, and marram grass as the main pollen sources, with exposure varying between the exposed coastal areas and the more built-up naval city centre. Surrounding North Holland farmland and the Waddenzee coastline contribute additional pollen, while strong onshore North Sea winds frequently disperse pollen across the peninsula city.

How often is the Den Helder pollen forecast updated?

Does pollen in Den Helder 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 Den Helder 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 Den Helder, 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.
