Local Environmental Conditions
Near Jarosław, oak and linden make up the bulk of local tree pollen close to the San River, and grass from nearby Podkarpackie farmland extends exposure through grass. Exposure here varies between the leafier fringes and the more built-up centre of Jarosław, particularly during the height of the season.
From an early hazel and alder start, Jarosław's season gets underway by January, before oak and linden takes over as the dominant spring pollen source; grass then extends exposure into early summer, with the full window running January to August. Rainfall and stronger winds later in the season generally bring the clearest conditions here.

How often is the Jarosław pollen forecast updated?

Does pollen in Jarosław 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 Jarosław 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 Jarosław, 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. |
