How to connect?

In Naaldwijk, tree pollen comes chiefly from oak, birch, and linden planted through parks and streets, with the built-up core generally registering lower counts than the surrounding green fringe. the Westland greenhouse belt and the wider Zuid-Holland agricultural land also feed grass and tree pollen into the area, consistent with Naaldwijk being a greenhouse district town.

How often is the Naaldwijk pollen forecast updated?

Does pollen in Naaldwijk 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 Naaldwijk 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 Naaldwijk, 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.
