Local Environmental Conditions
oak and birch lead the tree pollen count around Piastów's Utrata stream, while grass pollen from Mazowieckie farmland builds steadily through grass. Greener stretches near the Utrata stream see noticeably higher counts than the more built-up parts of Piastów, especially on still, sunny afternoons.
Piastów's exposure begins with hazel and alder, typically from February, and shifts into a oak and birch peak through spring; grass rounds out the picture into early summer, with the season covering February to August. Local wind exposure near the local parks and green spaces plays a role in how quickly counts clear on any given day.

How often is the Piastów pollen forecast updated?

Does pollen in Piastów 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 Piastów 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 Piastów, 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. |
