Local Environmental Conditions
Local tree pollen in Oisterwijk traces mainly to oak, birch, and linden in parks and gardens, and readings can differ sharply between the town centre and its greener suburbs. Nearby, the Oisterwijkse Bossen forest and fen lakes together with Noord-Brabant farmland contributes further grass and tree pollen, in keeping with Oisterwijk's character as a forest and fen-lake village.
From a January opening of hazel and alder, Oisterwijk's pollen season builds to its birch high point by April and continues into August. Oak and ash pollen build through April and May, handing off to grass as the leading source in June and July. the Oisterwijkse Bossen forest and fen lakes has a bearing on how quickly pollen disperses, and the Kampina and Oisterwijk nature reserves is a notable part of life around Oisterwijk.

How often is the Oisterwijk pollen forecast updated?
The Oisterwijk pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Oisterwijk 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 Oisterwijk 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 Oisterwijk, 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.

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. |
