Local Environmental Conditions
Jindřichův Hradec's tree pollen is dominated by oak and hornbeam, a pattern typical of South Bohemian Region and reinforced by its position on the South Bohemian lake plateau; grass and late-season herbs adds further exposure from nearby farmland through the warmer months. Parks and leafier streets tend to register higher counts than the built-up core.
hazel and alder opens the pollen season in Jindřichův Hradec as early as February, with oak and hornbeam building through the following weeks before grass and late-season herbs carries exposure into early summer; the overall window runs the February-to-September window. late-summer mugwort adds a further, generally mild stretch of exposure. Conditions on the South Bohemian lake plateau shape how quickly pollen disperses once the peak has passed.

Does pollen in Jindřichův Hradec 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 Jindřichův Hradec 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 Jindřichův Hradec, 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. |
