Local Environmental Conditions
The tree cover in Tiel leans heavily on oak, birch, and linden for pollen production, with the built-up core generally registering lower counts than the surrounding green fringe. the Waal river and the wider Gelderland agricultural land also feed grass and tree pollen into the area, consistent with Tiel being a river-orchard town.
Tiel typically records its earliest pollen in January from hazel and alder, moving into a birch-heavy stretch by April that runs through to August. By April and May oak and ash are releasing pollen, and grass takes the peak position from June through July. the Waal river plays a role in how pollen clears the area, alongside the fruit-growing Betuwe orchard region that marks out Tiel within Gelderland.

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