Local Environmental Conditions
The Skora River setting around Chojnów favours oak and linden as the dominant tree species, and grass from neighbouring Dolnośląskie countryside keeps counts elevated into grass. Wetter or windier spells generally bring the clearest air across Chojnów and its surroundings, cutting counts noticeably within a day or two.
The pollen calendar in Chojnów starts with hazel and alder in February, and shifts into a oak and linden peak through spring; with grass adding further exposure across early summer, spanning February to August. Farmland and any nearby woodland around the local parks and green spaces tend to keep background counts topped up through the peak weeks.

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