Local Environmental Conditions
As part of Blagoevgrad, Sandanski lies in the Struma valley beneath the Pirin mountains and sees birch and oak as its main tree pollen contributors; grass builds from the surrounding countryside as spring advances. The town's mix of open and built-up ground means exposure is rarely uniform across the area.
hazel and alder marks the opening of Sandanski's season, birch and oak follows as the main spring driver, and grass keeps levels up into summer across the February-to-September window. a late-season tail from mugwort and ragweed lingers into early autumn near farmland. The surrounding Blagoevgrad landscape, in the Struma valley beneath the Pirin mountains, plays its own part in how the season unfolds locally.

How often is the Sandanski pollen forecast updated?

Does pollen in Sandanski 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 Sandanski 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 Sandanski, 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. |
