Local Environmental Conditions
In Culemborg, tree pollen comes chiefly from oak, birch, and linden planted through parks and streets, though the gap between centre and edge can be considerable depending on wind direction. the Lek river and the surrounding Gelderland farmland add substantial grass and tree pollen to the mix, especially given Culemborg's role as a small fortified river town.
Culemborg sees its first pollen of the year from hazel and alder in January, with birch taking the lead through April and the season extending to August. Oak and ash step in during April and May, after which grass becomes the standout source over June and July. With the Lek river nearby, dispersal patterns shift accordingly, and the Betuwe orchard belt rounds out the picture for Culemborg.

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