Local Environmental Conditions
Local tree pollen in Winterswijk traces mainly to oak, birch, and linden in parks and gardens, and levels shift depending on how close residents are to parks versus the built-up core. the Achterhoek farmland and Duitse Border woodland, alongside the Gelderland farmland around Winterswijk, brings extra grass and tree pollen into an area known as an eastern-border farmland town.
January marks the start of Winterswijk's pollen year, led by hazel and alder before birch dominates through to April, with the season closing out in August. Through April and May, oak and ash add to the load, with grass then leading through June and into July. the Achterhoek farmland and Duitse Border woodland shapes local dispersal, while the hilly Achterhoek border landscape adds to the seasonal picture around Winterswijk.

How often is the Winterswijk pollen forecast updated?

Does pollen in Winterswijk 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 Winterswijk 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 Winterswijk, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
