Local Environmental Conditions
Weert's Dommel and Tungelroyse Beek river corridors feature oak, birch, and linden as the main tree pollen sources, with exposure varying between these green riverside areas and the more built-up city centre. Surrounding Limburg farmland and the Weerter- en Budelerbergen woodland and heathland contribute substantial tree and grass pollen, while the flat, open landscape allows pollen to disperse readily under prevailing westerly winds.
Weert's pollen season runs from January through August, opening with hazel and alder from January before birch peaks through April. Oak and ash follow through April and May, with grass peaking through June and July. The Weerter- en Budelerbergen woodland and heathland contribute substantial tree and heather pollen during spring, while surrounding Limburg farmland extends grass pollen into August under prevailing westerly winds.

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