Local Environmental Conditions
Svishtov's tree pollen is dominated by birch and oak, a pattern typical of Veliko Tarnovo and reinforced by its position on the Danube river bank in northern Bulgaria; 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.
The pollen calendar in Svishtov runs February to September: hazel and elm first, a birch and oak peak through the middle stretch, then grass and late-season herbs carrying things into summer. ragweed adds a further stretch of exposure into September across open countryside. Svishtov's location on the Danube river bank in northern Bulgaria tends to soften the tail end of the season.

Does pollen in Svishtov 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 Svishtov 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 Svishtov, 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. |
