Local Environmental Conditions
Around Leżajsk, oak and pine account for most of the tree pollen near the San River, and grass from nearby Podkarpackie farmland extends exposure through grass. Local wind patterns around the San River help clear the air on breezier days, though calm spells can let counts build up locally.
Early in Leżajsk's season, hazel and alder sets things off around January, and oak and pine then leads the spring count; grass then carries exposure into early summer, running January through August overall. River and valley air movement plays a role in how quickly pollen clears in Leżajsk.

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