Local Environmental Conditions
Tree pollen in Chorzów is dominated by oak and birch, concentrated around the Rawa River corridor, and grass from neighbouring Śląskie countryside keeps counts elevated into early summer. Greener stretches near the Rawa River corridor see noticeably higher counts than the more built-up parts of Chorzów, especially on still, sunny afternoons.
The first pollen of the year in Chorzów comes from hazel and alder in February, before oak and birch pollen becomes dominant across the spring months; before grass adds a further tail across early summer, the window spanning February through August. Calmer, drier stretches tend to let pollen linger longer here than in windier weather.

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