Local Environmental Conditions
Wieluń's Warta headwaters area sees oak and pine as the leading source of tree pollen, and grass adds a further layer of exposure from grass onward. Exposure here varies between the leafier fringes and the more built-up centre of Wieluń, particularly during the height of the season.
Early in Wieluń's season, hazel and alder sets things off around January, then a oak and pine peak takes hold as spring progresses; before grass keeps levels up across early summer, the season spanning January to August. River and valley air movement plays a role in how quickly pollen clears in Wieluń.

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